First photography lessons

Ive really enjoyed my photography lessons so far. We only have it once a week on a Wednesday afternoon. The first lesson we were in the dark room and we made photograms. You don't actually need a Camera for photograms. You just put some objects on photographic paper and expose it to light so that the pattern shows through. For example keys, or a bracelet. The longer you expose the photographic paper to light, the darker it will get when you develop it. So if you have an object covering parts of the paper from the light, it will stay white.
    After we've made out photogram designs we develop it still in the dark room because you cant expose paper to light. Their are 4 stages to developing a photo/photogram. First you put it in the "developer" for 1 and a half minuets. This is a slightly Alkali substance. When you put the picture in their you see it developing over time. Next you put it in the "stopper" which is slightly acidic,  you can also use vinegar for this if you really had to. You leave it in the stopper for 30secondds before transferring it to the "fixer" for 2 minets. After this stage, you can take your picture into the light. If you like it, put it in the wash (massive tank of water) for five minuets to wash the chemicals off. Then dry it and its done!!!

After we did photograms for a few weeks we did pinhole photography. This also doesn't require a camera, but a light proof box. This box has a tiny hole on it which you can cover.
You put a piece of photographic paper into the box and take it outside. You need to have bright sunlight. you point the box at whatever you want to take a photo off...either a person or a building etc. The you uncover the pinhole. The light reflects of whatever's in view and shines through the tiny pinhole, that acts as a prism, and onto the photographic paper. You do this for 30 seconds approximately, depending on how bright it is, Then you recover the pinhole and take it to the dark room to be developed, exactly the same way as a photogram. When you develop pinhole picture, they come out as negatives, so you need to reverse them. You lay the picture face down on top of a blank piece of photographic paper, inside a glass lid. You expose it to light, then develop it again. Then you have a picture.
With pinhole photography, if you a photographing a person you need them to stay really still. If they move, whatever is behind them will be in the photo as well. If there is a brick wall behind a person and they move their head. When you develop the photo the person will have their head but it will be see through with the brick wall imprinted on it.

I've really enjoyed photography so far. I love the fact that i now know how to uses a dark room. We are also keeping a black paged A4 journal to keep all our darkroom work in. The only problem is the photographic paper is £25 ponds a pack. But its worth it because i find i like the pictures so much better when i know its me thats taken and developed it.
