The Best Laid Plans of Mice and Men

So I've been playing about a bit with PhotoPills recently, a really geeky photographer's planning App. There's a steep learning curve, but once you've got the gist of it, it's really quite useful, particularly for sun/moon-set/rise shots and astrophotograpy. I'm not a huge fan of shooting the full moon - it can be a bit bland because the crater shadows are so short (like shooting terrestrially at noon), but if the moon is positioned well, it can still give usable results.

Back in June I already tried shooting the full moon rising behind Kloster Andechs, a local landmark. Unfortunately I got my planning slightly off, meaning that the moon was much further south of the monastery than I'd envisioned, it was a day past full moon due to cloud cover the night before and despite having clear skies at home, there was a cloud bank low on the horizon to the east, obscuring the view and it was quite dark.

Back home I went over the PhotoPills planning again and found out what my problem was. There are a number of variables that have to be entered; position of the subject, position of the photographer, time, etc. The App determines the distance between the two as well as the elevation distance and you can then select the precise time at which the moon will be at the correct elevation and work out the optimal place to stand in order to fine-tune the position to shoot from. It turned out that I'd taken the elevation into account and then used the wrong line in the map - the one 

Come July and the full moon fell on a Friday again, always good for a late shoot, plus moonrise was 8 minutes after sunset, meaning that there would still be a significant amount of ambient light to shoot with; it wouldn't just be a bright moon against a dark background (🥱). Back in PhotoPills I realised that I'd forgotten all the steps necessary to plan the shoot, so it was back to their helpful YouTube tutorial for a quick refresher.

  1. Subject to be photographed
  2. Standpoint to shoot from
  3. Second panel of Planner
  4. Altitude difference standpoint ⇾ subject
  5. Dial in Moon height using time slider (8)
  6. Line indicating direction of moonrise
  7. Line indicating direction of moon at selected time
  8. Time slider (magnified view).

Slide the time slider back and forth to give the correct elevation to match the altitude difference (4) and then reposition the standpoint pin (2) to position the moon direction line (7). Simples!
Getting into position about a half-hour ahead of time we discovered that the place on the lake shore that we'd worked out in the App was obscured by 2 m high reeds and so we backtracked 150 m north to just outside the Wasserwacht by the Pavillion at Utting. Waiting for the moon to appear we scanned around us for other motives. The sky colours were getting really pretty and pastelly at this stage and so I whipped out the smartphone for this grab. Actually one of my favourite of the evening in the end.

Moonrise came and went and we didn't see anything. Check the App. Oh yes, we have to wait for it to rise sufficiently to be seen behind the 173 m higher horizon to the east. I'd figured that into the planning, but I'd been looking at the moonrise time rather then the time that I'd dialled into PhotoPills. Bang on 21:33 we saw a red-pink glow on the horizon north of the monastery. Our move to a clearer spot had pushed the moon further north than I'd hoped for.

Starting with the moon 'upstream' of the monastery was much better than downstream, however, since it could only move into constellation and not out of to start with. It was now a waiting game, waiting for the moon to come into a good position, adjusting the tripod position every now and then to make sure the reflection of the moon's light was unobstructed - it would have been messy to have it interrupted by the boats or jetty at this stage. Avoiding this meant repositioning the tripod every five minutes or so.

With  as spectacle like this, we weren't the only 'togs out of course. Not sure whether this chap was a planner or an opportunist staying at the local campsite. I always go out of my way and exchange a few friendly words with anyone out shooting. I seem to get two types of reaction; folks are either really ultra friendly and chatty or they give the impression that you're treading on their toes, poaching their photos. It isn't a competition and generally we can only learn from each other. I'm always happy to promote other's photos on social media too if I see merit that deserves sharing. We need to be building each other up, not tearing each other down.

As we watched the moon rise, we could see the transition in colour from red to orange to yellow. Just like the sun, the more atmosphere the light reflecting from the sun has to travel through, the redder it appears as the shorter wavelengths of light get bounced off into space. Now we could zoom in with the Olympus f/5.6 100-400 to catch a couple of full frame images. Believe it or not, I've toned down the saturation of the moon here as it looked simply too artificial.

As the distance between moon and monastery increased, so the size of the two elements in the picture as I had to zoom out as well as the contrast in brightness as dusk slowly arrived. Our work here was done. Almost. Sharon actually spotted this composition of the light playing on the water next to the jetty. And with that we were done.

Do you have a subject that you'd like to shoot at full moon some time? Want some help planning exactly when and where to stand to take that shot instead of using trial and error? Drop me a line and we'll see if we can set you up.

My Latest Muse - It's Serious!

Hi folks, I know it's been a while - no posts for the whole of June 😲. I have been busy shooting, honest, but not much worth blogging about. Plenty of photos, but few words to go with them. I do have a new muse though. It's alright, Sharon knows about her. In fact she didn't even mind me creeping into bed at 2 am Saturday morning having spent the entire evening with her. It's a place, not a person and I've lived a 35 min drive away for the last 18 years and only just got round to visiting.

The place in question is, unusually for me, a flat piece of ground, albeit within spitting distance of the mountains. What makes it special is the buildings - it's a satellite communication centre, an arable area spotted with massive 32 m diameter parabolic antennae. What makes this place special though is that it's also home to a beautiful little 600-year old Bavarian chapel; St. Johannes d. Täufer (St. John the Baptist). The whole site is so delightfully incongruous, firstly with the massive satellite dishes set in amongst the farm fields and then with the combination of the dishes and the ancient tiny church. Add a backdrop of the Alps - you're pretty much looking directly at the Zugspitze, Germany's highest mountain and I feel like the whole thing is a microcosm (or is that macrocosm) of my life - science, church, mountains.

Despite the 'incongruousnous' of the place, it works, there's tension between the elements, but there's also harmony. Visually, the tiny chapel easily holds its weight against the dozens of satellite dishes. This feels like my life to a certain extent, I live in multiple communities; my work community is very science laden with friends who are sceptical about people of faith, some parts of my faith community, my church, are wary about too much science, other communities I belong to are salt of the earth Bavarians where I live or people who share our love for the mountains. Here in Raisting it all comes together.

I've been down here three times in the meantime and I don't plan on stopping any time soon. The first time was to try an astro-shoot, the second after a massive rain storm came through and the third to try to catch the blue hour and some more astro shots. Given the right conditions, shooting the Milky Way here could be quite interesting. The trouble is, the dishes are quite well lit at night, obliterating any long exposures for the foreground. Add to that that both times I've been to shoot the stars there have been residual clouds reflecting light from the surrounding villages and you get a frustrating constellation (no pun intended, honest). The night sky is really dark and getting the best out of it requires long exposures to collect as much light as possible. If you've got wisps of cloud, even if they're not visible to the human eye, they catch the light being cast up from the villages below and as you'll see at the bottom of this post, it gives the night sky an ugly orange cast.

I'm not going to show any photos from the first trip, they're just not worth it. I arrived late, set up where I thought there might be a nice view and shot into glaring spotlights all evening. The second time was quite special though. I went down with the whole family on the tail of a June thunderstorm. After eating at the delightfully Bavarian Gasthaus Drexl, we emerged to see the setting sun firing up the stormclouds that were slowly disappearing eastwards. What we hadn't expected were all the storks we saw. Sharon had glanced up as we left the Gasthaus and initially thought some silly bugger had posted a plastic bird on a scrappy nest atop their chimney, but then it moved and then we saw the chicks. Over the course of the evening we must have seen a dozen or so of the birds out in the fields, presumably looking for frogs and mice to bring back to their young.

The parabola dishes catch the evening light very satisfyingly, their structure catching the golden rays and reflecting them back. Some of the installations almost look like families with mum and dad towering over a clutch of infants.

The dishes are also thankful subjects for a monochrome treatment of the images. Here the combination of textures and tones screamed for a monochrome conversion. I pulled out the whites and blacks to make sure the image covered the whole gamut of black to white, added some dramatic contrast to the already moody clouds and sharpened the photo a little to arrive at this hangable composition.

My third trip was after a week of rainy storms had formed an impromptu lake in the middle of the fields allowing me to capture this reflection of the dishes dwarfed by an ancient oak tree. Getting low to the water let me catch some of the antennae with the mountains behind.

This time I was meeting up with a fellow photographer from Munich. Without him I would never have stepped behind the ancient chapel, but I'm so glad that I did just after the sun had set. Catching the colour of the last rays through the church windows together with the silhouette of the southwesternmost dish was a great start to the night.

One of the nocturnal summer phenomena that I've only recently become aware of, thanks in part to Alyn Wallace's informative "What's in the Night Sky" YouTube series, is that of noctilucent clouds. They can be seen throughout the summer night, mostly to the north as these high altitude ice clouds catch the last of the sunlight. According to Wikipedia, these are normally only visible from about 50° latitude, meaning that they can be seen from the very northern tip of Bavaria. We seem to have had some luck in recent weeks and I've seen several photos of them in and around Munich and saw them myself when trying to catch the moon rising behind Andechs monastery a week previously. Being so far south I could only just see them dancing on the northern horizon, but they're definitely NLCs!

Having said that this next and last photo would never see the light of day, I am actually going to post it here. For one it highlights (sic) the problems of astrophotography in areas with urban light pollution, even when it's as sparsely populated as the area south of Dießen. Even the slightest amount of cloud catches the street lights and reflects their garing orange glow back to the camera as you can see here. But the reason I decided to share this image is the excitement that it gives me. This is a 3 min exposure at ISO 800 and not only can you see the beautiful textures of the galactic core, but also star colour is becoming visual. This is a quantum leap forward in my astrophotography, made possible by my Move Shoot Move star tracker, a device that sits between the tripod and camera and, when pointed at Polaris, rotates the camera at the same speed as the earth. Without it, my maximum exposure time is 25 s before the stars start to become streaks. With it I've been able to capture up to 8 min exposures with the stars remaining pin sharp. This allows me to lower the ISO and increase the colour information captured on the sensor. The downside is that, as you can see, with the camera moving even this slowly, any ground becomes blurred. Normally this would be overcome by taking a second similar exposure with the tracker turned off, but I had some technical issues with the untracked images and so this is about as good as it gets under the circumstances.

This is definitely not the last you'll be seeing of the Erdfunkstelle Raisting from me; there's a lot more motherlode to be mined here. Watch this space!
