Back in June I made two pinhole cameras to start solargraphs that would record from the summer solstice until the winter solstice. One camera was placed outside my house and the other outside my office where they, incredibly, remained untouched.
The first one I checked out was the one at my office and I was delighted to see the sun tracked through the six months. You can see our hot summer and the cloudy days that followed. Unfortunately there wasn't much else in the detail - you should be able to see a small Edinburgh Castle in this shot as well as the buildings of the New Town. The second solargraph outside my house had nothing on it which confused me further.
So what went wrong? I've had a good month to think about this and can only put it down to the paper I used. The science behind a solargraph is simple and there is no reason for it not to work but I used a photo paper that I make my darkroom prints on and it's completely different from the resin coated paper that you would expect to use in these cameras.
That said, I actually really like the image I did get. There is an air of mystery about it and it certainly isn't your usual solargraph. I will load up the cameras again and see what I can create this time with different paper.
