Sunset From The 'High Ridge'

Matthias' message warning me that the forecast was set for sensational sunsets at the weekend reached me on Thursday evening. At the same time he informed me that he was waiting for confirmation that he hadn't been infected by a colleague and so we'd have to play it by ear. In the meantime: where to go to catch the spectacle? I immediately recalled a tour that we'd done as a family earlier in the year in the western Allgäu mountains and where we'd had an uninterrupted view towards the Säntis in the north-eastern corner of Switzerland.

Looking through our hiking book for the Allgäu, Sharon found a suitable looking tour just north of our previous jaunt, involving the summit of the Hochgrat. Looking it up online, I noticed that they had a cable car up to a few meters below the summit with a mountain restaurant and that they were advertising late opening due to the full-moon. Slowly a plan was forming in my mind involving an epic sunset shoot followed by some cool blue-hour photos by moonlight.

By Saturday morning, Matthias still hadn't received the all-clear, so we reluctantly decided that we would be better off going our separate ways this time - a decision that I don't think either of us regret given the images we were able to capture. Given the fact that we were planning a relatively late shoot, we weren't in a hurry to leave on Saturday morning. 

Into the Aubach Valley || Olympus 44 mm, f/8, 1/160 s, ISO 200
We'd planned to park well up the Aubach valley at the Alpe Scheidwang, but after having have to wait for a small herd of cows to be ushered down to their winter quarters (the Alpine 'Almabtrieb' tradition - usually quite a photogenic event) we drove up to the bottom of the toll road to find it closed for the winter already. This put 8 km (5 miles) onto both ends of the walk, but we weren't going to be put off so easily.

The Aubach valley is delightful and full of deciduous trees. Unfortunately we were a few weeks too late for the best colour ('peak fall'), but we were still treated to a few last silver birches glowing golden in the afternoon sun. The polarising filter really brought out the sky's colour, bringing the cirrus clouds drifting overhead into stark relief.

Golden Silver Birch || Olympus 12 mm, f/6.3, 1/125 s, ISO 200
The unexpected extra mileage meant that we didn't have much time to enjoy the valley, but there are a number of waterfalls left and right of the trail that would warrant a more leisurely investigation another time under the right conditions. The live ND function on the new Olympus makes shots like this child's play (if you can find them that it). The on-board computer can simulate a 5-stop light reduction.

Roadside Waterfall || Olympus 61 mm, f/8, 1 s, ISO 200
One of the Olympus features that caught my attention and caused me to opt for this system over say those of Fuji, Sony, Canon or Nikon was the image stabilisation - an exceedingly clever system that compensates the movement of the photographer and enables you to still get remarkably sharp photos. The shot above, for example, is a 1 s exposure. As a rule of thumb, without any stabilisation (unless you have a really steady hand) is that the shutter speed shouldn't exceed 1/focal length (e.g. 1/50 s for a 50 mm lens). Being able to take shots like this hand-held is a huge advantage. Add to that the brand new in-camera ND filter (neutral density - a darkened filter that is pure grey) and you've got a winner. The Olympus E-M1X had this and so does the new E-M1 Mk III, of which I have been a very happy owner for about a month now.

Climbing out of the valley towards the ridge and our destination - the 1834 m high Hochgrat - the snowy tops of the inner-Alpine peaks began to show themselves. The previous morning there had been snow even on the northern edge of the Alps and there were signs of fresh snow, but they quickly disappeared over the course of the day. As we climbed out of the valley and could peer over the edge we could see that the main Alps hadn't shed their white blanket so easily.

Peeking Over The Edge || Olympus
As we climbed towards the ridge, it wasn't only more mountains that we could see, but more people as well. There's a cable car that runs up to a point about 80 m below the summit starting near the town of Oberstaufen on the other side of the mountain to where we started from. Due to the full moon, the cable car was running until 21.00 and a lot of people were understandably making the most of the last Saturday before the renewed lockdown to tank up on fresh air.

Catching the Sunset

Despite the larg(ish) numbers of people, there was plenty of room on the summit to settle, grab a snack and wait for the ensuing spectacle. There wasn't as much high cloud as there had been the previous evening, but the remnants of cirrus clouds, particularly on the western horizon, gave us hope. Although I'd deliberately chosen a spot on the very edge of the summit and demonstrably got my tripod out and ready, it didn't stop another photographer from setting up between us and the sunset. To be fair, he probably hadn't noticed me - my tripod was out but not extended, but it still left me fuming at him (silently of course, I am British after all) and so I demonstrably set up just left of him as we waited for the show to start.

As well as the main view in front of us, the slowly setting sun was beginning to light up the bigger mountains of the Allgäu in a very alluring fashion. Taking panoramas like this I'm always torn between the bigger picture and detailed shots of individual mountains and larger panorama shots. I must have swapped between the 12-100 mm and 8-18 mm lenses half a dozen times as the evening progressed, depending on how the fancy took me.

Then it was just a question of waiting. Exposing sunset photos is far from easy. Either you get a well-exposed foreground and a pale sky with a burnt-out spot where the sun should be, or a dark foreground and a brilliant sky. Working with a tripod it was relatively easy to take multiple exposures of each shot and put them together afterwards in ON1 Photo Raw. This is necessary because our cameras are not as good at resolving the range of bright to dark as the human eye is. Normally when I'm 'exposure bracketing', I'll set the camera to 1/4 and 4x the light (two stops under and two stops over), this time two stops wasn't going to do it and so I went to three (1/8 and 8x the light) and even then it was borderline shooting directly into the sun.

Even with these precautions, the sun was almost too bright for the camera as it dipped behind the Säntis.

Always Wait for the Encore

About 18 years ago, the band Blackmore's Night was playing one of the local concert venues. The eponymous Richie Blackmore was the one-time lead guitarist of two of our favourite bands (you may have heard of them; Deep Purple and Rainbow 😉). The newer music style of Blackmore's Night is a bit twee and wasn't really worth hanging around for the encore for, so in order to beet the rush for the car-park (and keep the babysitter's fee to a sensible level) I suggested that we cut out early. We were just walking across the road when I heard the opening chords of "Difficult to Cure" - Rainbow's rock adaptation of Beethoven's 9th and one of my favourite tracks of theirs. The hairs immediately stood up on the back of my neck and we did a volte face and marched back into the courtyard to enjoy a great rendition of this rock classic. Why am I telling you this? Well the moral of the story is that as with concerts, when photographing sunsets, you should always wait for the encore. Once the sun dips below the horizon, it lights up the clouds from below leaving you with the classic breath-taking oranges, reds and purples - and yes, sometimes even deep purples.

Always Wait for the Encore || Olympus 25 mm, f/8, 1/50 s, ISO 200
Another good tip for photography in general is that you should always look over your shoulder for the unexpected scene. Despite wanting to get to the restaurant before the crowds did - we knew that we were going to be around for a while yet for the blue-hour - we spent a couple of minutes scouting the area for some last shots before setting off down the path to the top of the cable car to grab some well-deserved chow. I've had better food in the mountains, but sitting outside on the terrace of the restaurant I don't think I've had many better locations.

On to the Blue Hour

As we polished off our venison goulash on the terrace overlooking the valley, or Käsespätzle in Rhi's case, the lights started to come on, both in the valley and above us. I absolutely love blue hour photography. Since my stint in the Allgäu shooting the Milky Way back in June, I've become an ardent fan of this time of day. Every photographer has their favourite light. For some it's the hour before sunrise, when lakes are still mirrors and mist hangs in the valleys, for others it's the golden hour, that time just after sunrise or just before sunset when the light turns that gorgeous colour, illuminating subjects gently from the side. Mine is the evening blue hour, catching the sky as it turns pastel shades of yellow to purple. If I'm in the mountains, and even better, if there's fresh snow on the peaks, then I'm in heaven. I was in heaven:

Not only was the view to the south hotting up (above), the lights were beginning to show in the valley. Dusk photography is always fun - you invariably end up getting details on the photos that the native eye didn't spot. Although the eye has a greater dynamic range than the camera sensor, the sensor is more sensitive to low levels of light, especially if you keep the shutter open for a few seconds as here. I never noticed The Plough when I was taking this photo, but it's staring you in the face here.

The Plough over Oberstaufen || Olympus 10 mm, f/3.1, 30 s, ISO 200
But the sunset wasn't the only heavenly spectacle that the evening had prepared for us, we still had the full moon to go. It was low on the eastern horizon as we started off on our three hour trek back to the car. I tried a couple of shots, but couldn't get the focus properly - always a problem with low light photography. Yes, yes, I know the Mk III has the super-duper star AF mode, but in my rush I completely forgot about that, and wouldn't have known where to find it in the dark even if I had. On top of several expertly exposed shots that would have looked brilliant if I'd got the focus right, I managed to squeeze this last shot off my focusing on Mars. 

Allgäu by the Light of the Moon || Olympus 9 mm, f/3, 30 s, ISO 800
The moon was so bright that we didn't even need the head torches that we'd brought with us. The long yomp along the Aubach really dragged on the way back, leading Rhiannon (girl-child) to issue the warning "the photos better be worth it!". I'll leave you to be the judge.

Oh, and Matthias tested negative.

Feedback on the First Workshops

"Apparently, if you try to cram two years of learning into 4-6 hour 1-2-1 workshop, the participants can find it a bit too much. Who knew?"
The Old Gypsum Mill || Olympus f/5.6, 1/125 s, ISO 1250 

I’ve now run my first two workshops for volunteer guinea-pigs recruited from among my local friends on the understanding that they would give me in-depth feedback on the sessions in lieu of payment. We had two great afternoons, one hiking in the local mountains in less than perfect weather and one shooting flowers in a friend’s back garden. We had several “aha” moments as they learned things about their cameras that they didn’t know before and both have got some great shots out of the sessions. But what did I learn?

Over the last 18 months I’ve invested a lot of time in my photographic education. I’ve read books, I’ve watched a ton of videos and online courses on photography and post-processing and I’ve endeavoured to put a lot of it into practice in the field. I think that most people would agree with me when I say that I’ve come a long way photographically in that time. I’ve almost completely changed my approach to photographing and my philosophy of photography. A lot of things are now obvious that would have been a complete mystery to me even two years ago. I was an idiot to think that I could convey the significant parts of that learning in a single session, but that’s what I set out to do. Twice. In my defence, the second session was probably much better structured than the first. But I need to trim it down much further, or at least give the students more time to take each aspect of the teaching on board before progressing to the next.

Let’s take a look at the two sessions and try to assess what works and what doesn’t and look at how to build this into planning future workshops.

In the Pöllat River || Olympus f/11, 2 s, ISO 200


Session 1: In The Pöllat Gorge

The first session was held at one of my favourite local spots – the Pöllat gorge below the fabulous Neuschwanstein castle near Füssen. My student, a friend from the Munich choir that I sing with, had previously been a teacher – a huge plus for me, as this was someone who had first-hand experience of teaching methods and knew what he was talking about when it came to feedback. We’d had a chance to chat a little about photography on the way down in the car and I’d already sounded him out concerning what he wanted to learn.

The fun part about this session was that Andrew had a relatively clear idea of the images he wanted to get, but wasn’t always clear on how to achieve those images technically. This was definitely something I could help with.

Parking the car at the Tegelberg car park (much cheaper than parking in Hohenschwangau at the bottom of the castle), we trekked along the base of the mountain, the clouds lingering in the trees above us. Excellent opportunity for composition questions 1 and 2: (1) What catches your attention, and (2) what aspect of the subject do you want to emphasise or caricature? (thanks Joshua Cripps!)

Moody, Misty Forest || Olympus f/5, 1/200 s, ISO 500

Arriving at the bottom of the Pöllat gorge, I was dismayed to see that the gorgeous wooden mill race had been very badly damaged in the recent storms. I sincerely hope that they repair it using the original wood, since this has always been a complete eye-catcher and really strong element for photos here. As it was, the heavy flow was just gushing out of the broken end of the trellis into a mess of tree branches. Such a shame.

After we'd walked around the bottom of the gorge for a bit, scouting compositions, we went a few meters downstream where it was a little quieter so that we could chat about how to emphasise the water movement, leading into a discussion of long exposures and tripods. I'd established in advance that Andrew would be using the Nikon 18-55 mm kit lens and managed to source a cheap step-up ring of the right diameter so that he could use my filter system to create a series of shots with different exposures.

Shooting in the Pöllat || Huawei P30 Pro

Having had a good long session at the bottom of the gorge, we walked up through the shady forest, looking for other compositions. There are some nice shots to be had of the falls as well as some nice intimate forest landscapes - what my father calls my signature shots. The moss was particularly appealing 

Moss Micro Landscape || Olympus f/4, 1/8 s, ISO 200

At this point, I forgot a bit that I was supposed to be leading a workshop and got side-tracked by taking my own images - wrong of me I know, but too easy to do in the circumstances. In future, I'm really going to have to put my own shots in the background, unless they're to make a teaching point.

Carrying on up to the path between Neuschwanstein and the Marienbrücke, we were rewarded by a moody view over Hohenschwangau with the sun breaking through the clouds. An impossible shot for Andrew's camera, but no match for modern exposure bracketing. Once again, I was putting my own photos first. But come on, who would have said no to this:

God-Rays over Hohenschwangau || Olympus Exposure Bracketing

After waiting a while in vain to see whether the weather would provide us with anything better, we headed on up to the Marienbrücke, the bridge overlooking Neuschwanstein, to see whether the light would allow us to catch any useful shots. Andrew took quite a few from the bridge and we toyed with the concept of including some foreground in a shot in order to establish a bit of 3-dimensionality to the scene.

It was quite late by the time we got back to the car and we were both starving, so we looked for a suitable hostelry. Waiting for food, I had a chance to go through my workshop cheat-sheets with him. In my mind I had planned to shoot and then go over the theory in the hope that he would be more receptive to the concepts - a teaching style that we often use at work. In reality, it would have been helpful to look at them beforehand and then try to put some of it into practice in the field.


Session 2: A Munich Garden

For the second session I visited my friend in her garden in Munich. Because one of her primary photographic interests was flowers and because they have a beautiful flower garden, this really worked out nicely. The weather was definitely playing ball this time as well, which really helped. It had rained just before I got there, but we had a great 4 h in the garden in lovely late afternoon light, shooting anything and everything in sight.

This time we were able to sit down before we started and look at some of the concepts that help me focus on what makes a good photo. I was delighted that my friend was able to make the intuitive jumps from the things I was pointing out (more here) to compositional consequences. Once we'd got some of the basics out of the way, we were able to knuckle down to the two issues that she had highlighted approaching the workshop; exposure and focus.

Reach for the Sky || Olympus f/8, 1/250 s, ISO 200

After explaining the various ways in which cameras measure exposure and the shortcomings of assuming that everything is 50% grey, we looked around for potential examples. She has a beautiful honeysuckle growing up the side of the garage. Against the sky, most cameras will underexpose the subject to avoid an overly-bright image, leaving the subject quite dull. Exposure compensation to the rescue (once we'd found out how to in the manual).

Essence of Hydrangea || Olympus f/8, 1/40 s, ISO 200

Looking back, we should have spent a little while at least concentrating on exposure, but I was so excited with the progress that I was all for moving swiftly on to the next issue; focus. Once we figured out how to give her back the control over what the camera was focusing on we even got a chance to look at the concept of depth of field before switching over to her macro lens and fiddling about with focus magnification in a foreign camera system.

Old Wooden Chair || Olympus f/8

All in all we had a great afternoon/evening working through various technical and compositional aspects before I was gently told to stop - I'd passed on enough information and time was required to process and practice.

Lessons Learned

What Went Well

Let's start with what went well:
  • The second workshop was much better structured than the first, working through the teaching materials and having a chance to put it all into practice.
  • Knowing both locations well before the shoots was essential. Even then there were surprises, like the demolished mill race at the Pöllat gorge.
  • Both locations were good and had some 'gimme' images where you couldn't really go wrong, whether Schloss Neuschwanstein or my friends gorgeous garden.
  • Having a few toys to hand to play with worked well, such as the ND filters for the gorge and my tiny fish-eye lens as a demonstration of how aperture works.
  • Getting the students to fill out a self-assessment form (below) well in advance of the workshop so that I could prepare a session to fit their individual needs worked really well.
  • The handouts I had prepared turned out to be really good teaching aids.
  • After the first workshop we sat down and went through a handful of the best images, looking at technique and possible tips. The offer is still out on the second workshop, but, life!

Challenges

  • One of the time-consuming aspects of both workshops was becoming familiar with other peoples’ cameras. After 18 months with my Olympus I can operate it pretty much blindfolded. Previously I’d been using a Panasonic bridge camera and so had at least a working knowledge of the menu structure. My students had Nikon and Cannon cameras respectively and finding functions in the various menus took time. If students aren’t familiar with their cameras, it’s essential that they bring the manual with them. It was also challenging switching between a mirrorless camera with all of the associated ease of use and the more flighty DSLRs.
  • The weather and, more importantly, the light during the first workshop was extremely challenging. But that’s life sometimes.
  • It’s important to establish ahead of time which lenses your students are bringing to the workshop. I’m used to the flexibility of being able to choose between ultra-wide angle, long telephoto and everything in between. Students aren’t always going to be able to bring that variety to the workshop and the location needs to be planned accordingly.

What Didn’t Go So Well

  • Looking back, although the first workshop was fun, setting out without covering at least the basic theory was a mistake. I was all gung-ho for the location and thought I could explain as we went. I couldn’t.
  • After the first few shots, I also assumed that the student was doing ok and didn’t need as much help or feedback. In future I’ll have to be more proactive in checking in with them.

Looking Forward

Looking forward, I think I will have to offer either one or the other; either a photo safari or a photography workshop. It’s much easier to concentrate on teaching skills in a calmer environment with few distractions, where we can sit down, talk about the principles and then put them into action.

On the other hand, once someone has mastered the basics, it will still be fun to head out to the hills to look at how to put those skills into practice.

My Questionnaires

I've created two questionnaires, one to give me a feel for the student's needs, one for them to give me feedback on the workshop so that I can continue to improve as an instructor. I'll reproduce them here for anyone wanting to use and adapt. I've created these using Google docs, and the answers flow directly into a table. I'm a huge fan of Google docs as they allow me to access the information on the go using a variety of platforms.

Student Assessment Form

I ask a lot about my students because I really want to understand their needs and offer a tailor-made session. It also helps them to assess where they are and think a bit about the issues involved. I also ask them either in advance of - or during the session how they would define a "good" photo. Although a straightforward question, it really helps focus on the issues.

I Can Slow Down Time, What's Your Superpower?

A while back I talked about some differences between our eyes and cameras, focusing primarily on things that our eyes can do but our cameras can't (When What You See Is Not What You Get). But there are also some things that our cameras can do that our eyes can't. One of these is slowing down time. Well, actually it's accumulating time. Ok, it's not accumulating time, it's accumulating light over a longer period of time, but you get the idea. Sometimes a slow shutter speed can be a real hindrance, such as when we're trying to take a photo of something that's moving quickly, or we're using a telephoto lens (or both - photographing birds in flight, for example). But sometimes, just sometimes, it can give rise to really cool effects to emphasise movement.

Between a Rock and a Soft Space || Olympus f/20, 5 s, ISO 200

Probably the most common use of this effect is emphasising movement in water, either in waves or in a waterfall. Take a high-speed photo of a waterfall and you'll freeze the motion, giving you a glassy image (which can also be appealing).

Glassy Water || Olympus f/4, 1/800 s, ISO 1600

Slow things down to a fraction of a second and you'll get a real sense of movement in the scene. Even 1/5 s is enough to really convey what's going on such as with this waterfall above Saas Fee in Switzerland. I love the contrast between the rocks and the water in shots like this - solidity and motion. 

In the Swiss Alps || Olympus F/22, 1/6 s, ISO 100

You can easily apply the same principle to waves on the sea, such as in this Boxing Day photo taken in Lyme Regis on the English south coast. My portfolio of seascapes is very limited, but this one taken in the later afternoon light works for me. The wave crashing into the sea wall is clearly in motion, as is the foam soaking back through the pebbles towards the sea.

Waves at Lyme Regis || Olympus f/22, 1/2 s, ISO 80

If you want to go full-on motion blur, giving you that creamy, foggy appearance in the water you'll need to further increase the exposure time to multiple seconds.

At the Stuiben Falls || Olympus, f/22, 5 s, ISO 64

But how do you take an otherwise sharp multi-second photo? There are essentially two challenges; (I) reducing the amount of light entering the camera to a sufficient level to allow a long exposure in the first place, and (II) stabilising the camera so that the rest of the picture isn't blurred.

Reducing the Light

Why do we need to reduce the amount of light entering the camera, and how do we achieve this?

Why Do We Reduce Light? There are two physical limits in our cameras to the amount of light being registered by the sensor; the size of the aperture (the F-stop) and the sensitivity of the sensor (ISO). Most lenses are restricted to a minimum (smallest) aperture of about F/22 and most cameras to a minimum ISO of somewhere between 50-100. On a bright sunny day, even F/22 and ISO 50 aren't sufficient to achieve an exposure time close to 1 s. The image will be completely over-exposed - simply put too much light has entered the camera, plus there are good reasons not to push either the aperture or the ISO this far; at F/22 most lenses exhibit sharpness-limiting levels of diffraction and at low ISO the camera sensor's ability to distinguish between the brightest and darkest aspects of a scene (the dynamic range) is slightly diminished. So in order to get a decent image, we need to reduce the amount of light hitting the sensor.

Photography 101: Include a Pretty Girl in a Yellow Coat || Olympus f/4, 1/5 s, ISO 200

How Do We Reduce Light? Essentially there's only one way to do this; sticking a piece of darkened glass in front of the camera lens There is another way, but that goes beyond the scope of this article. Most of us are familiar with polarising filters for cameras and these certainly help to reduce the light in certain circumstances, but are limited to somewhere between 1 and 2 stops. What's a stop of light?, I hear you ask. A stop in camera-speak is a doubling (or halving) of the exposure. So a polarising filter will generally allow you to double or quadruple the exposure time, say from 1/10 s to 1/5 s - which really isn't much at all. You'd hardly see the difference between the two.

The next easiest option is a variable neutral density (ND) filter. Have you ever tilted your head whilst wearing polarised sunglasses and seen a screen go dark? That's probably because the screen you're looking at is also polarised. As long as both polarised layers are aligned, no effect is visible, but as soon as the two layers become misaligned, a decreasing amount of light passes through both layers. This is how variable ND filters work. They have two polarised layers that can be turned independently meaning that you can control how dark the filter is. Although convenient, there are downsides to using variable ND filters. If you were to take a photo of a perfectly uniform surface through one of these filters, the resulting image would in all likelihood look quite blotchy because the filter effect is normally uneven. You wouldn't want to use this filter to shoot blue sky, for example. But it can work for irregular images such as waterfalls.

Beyond that you're looking at fixed ND filters, darkened glass that reduce the amount of light without affecting the colour of the light. These can either be attached directly to the lens via a screw thread or using a special filter attachment system. The darkest commonly available ND filter, generally referred to as the Super Stopper, reduces light by 15 stops 😲.

Such filters can even tame wavy lakes to add a sense of calm to what would otherwise have been a very unsettled image. On this windy late November morning at the Hopfensee there were a lot of waves and they would have detracted from the sense of peace I was hoping for with this image.

Dawn at the Hopfensee || Olympus f/11, 8 s, ISO 64


Stabilising the Camera

The rule of thumb is that the maximum length of time the average person can hold a camera before camera shake renders the picture unacceptably blurry is 1/focal length in mm. Sounds technical, but the focal length is essentially the amount of zoom you're using. Assuming that the standard lens has a focal length of 50 mm (commonly referred to as "a 50 mm lens"), then the accepted maximal exposure is 1/50 s. If you're using a wider-angle lens, such as a 20 mm lens then that time decreases to 1/20 s. If you're using a 300 mm telephoto, then the maximal exposure is around 1/300 s, quite fast and much too quick to smooth out any desired motion blur.

There are two ways to achieve stabilisation; either in-camera image stabilisation (whether camera body or lens) or camera immobilisation (e.g. a tripod).

Image Stabilisation When I was looking for a new camera at the beginning of 2019, one of the features that caught my eye was the excellent image stabilisation capabilities of the Olympus cameras. My E-M1 Mk II boasts a massive 5.5 stops of image stabilisation, even more in combination with certain lenses. What's a stop of image stabilisation? The same as a stop of light. Going back to the 50 mm lens, we mentioned above, I can double (or is it halve?) the exposure 5½ times from 1/50 s to 1/25→1/12.5→1/6.25→1/3.125→ >1/1.56 s - so about a second. 

Olympus' image stabilisation with the newest generation of cameras - the E-M1X and the E-M1 Mk III  (💗) is rated at 7.5 stops with certain lenses - turning 1/50 s to 3.6 s - practically an eternity in camera terms. This is pretty much getting to the physical limit for in-camera image stabilisation, which I am reliably informed is limited by the earth's rotation! This is all done using a free floating image sensor chip which is held in place using magnets.

Anyway, enough technical details and Olympus fanboy-ism, suffice to say that most modern cameras come with a certain degree of image stabilisation, allowing you to break the 1/focal length rule.

Don't Just Rely on the Effect - Use Composition Rules || Olympus f/6.3, 1 s, ISO 200

Camera Immobilisation The other way to prevent camera blur of course is to immobilise the camera itself. Classically this is done with a tripod, though we don't have to limit ourselves to this option. In an emergency, anything stable will do, a rock, the crook of  a tree, a rucksack or a beanbag. Anything that will prevent your camera from moving. They say that you should always turn your image stabilisation off when using any form of camera immobilisation. Apparently, the camera expects a certain amount of user shake and gets confused when this is absent. In practice, half the time I forget to turn off image stabilisation anyway and I can't say that I've noticed a difference.

For this to work, the surface that your tripod is resting on has to be stable too. There are a couple of gorges near where I live that have metal bridges spanning the river below. These bridges start to swing noticeably as soon as anyone starts walking along them, so sometimes a little patience is required.

Just know that you'll seldom be alone at spots like the Hopfensee. Matthias and I ran into a photo workshop later the same day as above. Still, you don't have to include the other photographers in the image.
 

So that's the basics of camera immobilisation. Choosing the right tripod is also a matter of taste and usually ends up being a compromise between weight, cost and stability. Don't skimp too much though as you will ultimately regret it. I'm currently running two tripods; my main one is a doughty Tiltall TC-254 which is currently sporting a Benro GD3WH geared head. I also have a lighter Rollei Compact Traveller for when I want to cut down on weight.

How Much Motion Blur?

How long is a piece of string? Honestly, there's no correct answer to this question, it's purely a matter of taste and depends a lot on whether you want to simply convey a sense of motion, in which case you can get away with exposures of around 1/5 s, or whether you want to give your waterfall that silky fog appearance, in which case you're going to need exposure times of at least a couple of seconds.

Waterfalls and Wildflowers - The Power of Separation

It won't come as a surprise to some of you to know that our medium-term plan is to up-roots here in Bavaria and settle in Austria. The intention is to semi-retire, earning a little bit on the side with photo safaris and workshops in the border area between Lienz and Cortina d'Ampezzo, between the main chain of the Alps and the majestic Dolomites. I've been working on my photography a lot over the last 18 months. I've come a long way in that time. I still have a way to go, but if I review my photos of the last few years, I can see definite progress. The Mike of 18 months ago would have a lot to learn from the Mike of now. I know that I've still got a ways to go, but in the near future I hope to start offering tuition on a 1:1 or 1:2 basis. The tuition can be in English or German, though preferably not both in the same session.

This won't be on a monetary basis, which doesn't mean the tuition will be free. Instead of remuneration, I will be asking for detailed feedback from you in order that I can hone my skills as an instructor. So, if you're in the Munich area and find yourself looking at my photos and saying "Wow, I wish I could take photos like that!", get in touch and we'll see what we can work out.

It would be useful for me to understand a bit about your current level of expertise as well as your aspirations before we start out so that I don't end up boring you with stuff you already know and so that I can plan the excursion to give you a chance of learning what you want to learn.

Unless you have a specific plan in mind, my recommendation would be that we head down to the mountains to somewhere like Hinterstein here and simply head up the trail. Tuition would involve a whole day spent in the wilds, so you'll need to be at least a little bit fit, though we will be stopping regularly for photos. Rather than classroom tuition, it will all be out in the field (or forest😉) showing you optimal camera settings as we go for the compositions as we find them. We'll discuss what makes good photos, what constitutes good and bad lighting (and why bright sunlight isn't always the best), how to separate subject matter from its environment to draw the viewer's eye to where you want it and how to use lines in a photo to do the same.

Zipfelsbach Waterfall || Olympus f22, 1/2 s, ISO 125

One of the first compositions on this particular tour, for example, is the Zipflesbach waterfall, where we could play with how the exposure time affects the appearance of the water and how to convey a sense of motion through slow shutter speeds. A tripod is a must for such shots on most cameras, and a neutral density (ND) filter can be very helpful to prevent over-exposure. At the very least, a variable ND filter, with two layered polarising filters that can be twisted independently in order to adjust how much you decrease the amount of light hitting the lens. Professional photographers frown on them because they can cause unsightly patterns on plain subjects such as the sky, but they're great on waterfalls. There are several schools of thought - or preference - concerning the optimal exposure time for moving water, varying from about 1/5 s, enough to convey a sense of movement without overdoing it, to 2 s for that real silky motion. Personally, I like the effect that can be obtained with a 1/2 s exposure, though I have been known to go to as long as 10 s for some of my shots of the Stuiben Falls and Pöllat Gorge.

Alpine forests are a treasure-trove of wild flowers in early summer (and mushrooms in the autumn if it hasn't been too dry), and there would be plenty of time to get up close and personal with orchids, wolfsbane and the like. Early summer is also great for fresh pine growth, which traps dew-drops and rain-drops beautifully.

Wolfsbane (German: Arnika) presents a great object lesson on how to photograph flowers with a little bit of imagination. There's a temptation to simply shoot flowers from head height - in my opinion, one of the worst perspectives to shoot from. It can work if done well, but it rarely has real impact. Get down low for a more oblique angle. In steep woodland it's relatively easy to get this sort of angle without breaking your back, it's common that plants are at waist height on the uphill side.

Here I took the spontaneous decision to take the unusual side-on shot. Depth of field is always a consideration for shots like these, you want it to be shallow enough to isolate the flower from the background without making the focal plane so narrow that virtually nothing is in focus. I got away with f4 here, though in retrospect I should have gone for a smaller aperture to get more of the flower head in focus. I'm still learning too.

Above the tree-line there are more wild flowers to be had and maybe even some bona fide landscapes. We were stunned by the number of wild gentians growing as we left the forest, together with marsh marigolds (a challenge for any camera due to the intensity of the yellow) and oxslips. Focus isn't the only way to get separation on subject matter, here I used light. With the sun shining on the pale yellow flowers it wasn't difficult to set the exposure so that they were well lit whilst the shadowy stream behind them was almost completely black.

The Zipfelsbach Alm has a small alpinarium with a lovely variety of mountain flowers including perennial cornflowers amongst others.

The path back down from the Alm follows the Zipfelsbach over a series of small falls before the trail drops back into the forest and then down along the side of the high waterfalls. There are multiple opportunities to stop and shoot the upper falls on the way down.
