Solargraph project - 2017 first half

In 2016 I’ve been at the Astro Camp organized by the Hungarian Astronomical Society in Tarjan. Two astronomers gave me 3 solargraphs, one I gave away for a good use to Northolt Branch Astro, one was a test and this one.

The solargraph was put out on 30^th January 2017 at Wimbledon Common at the windmill facing toward the Ranger Office. I really didn’t know what to expect from this project as this was my second solargraph in real use. It’s been collected on the 7^th June and made me so curious, what I might find inside the enegy drink can.

Here are some photos about opening the can containing the photo paper.

                          

But what is this thing called solargraph??

Well it is a very simple photographic camera for taking very very long exposure wide angle photos with a pinhole camera.
You use a box or a can, cut the top 1/3 off and put a light sensitive photo paper inside. So the paper is taped to the inner side of the can, whilst you make a whole onto the opposite side of the can, hopefully ending up with the pinhole camera.
After the paper carefully placed inside, taped at the top to hold it at a fix position, we close the can and tape it around to seal it from water, humidity etc. It is that simple.

But I have never made one myself yet, but definitely will in the future because solargraph is a lot of fun!!

But let's see the result of 127 days of waiting. The original photo that came right out of the can is on the left. The one on the right is post processed in Photoshop. 

    

And finally this is a video summary about the whole project. Couldn't document as professionally as I planned, but let's say this was the first step on this long road :)
