Film Cameras- Chemigrams

In this workshop we were experimenting with film cameras. We had a variety of subjects in the studio to photograph:
- Sunflower placed on a black background with one light source
- Stone and fircone (as above) 
- Marmite jar (as above) 
- Doll on a white background with a constant bright light and a second light to the left. 

We also took the camera outside and photographed locations around college these used natural light. 

We used manual controls on the camera to adjust the aperture and shutter speed depending on the amount of light coming into the camera lens. 
For example if it was a really bright day and there was a lot of light the aperture needed would be smaller; the F number would be larger. If there is a shaded area you would need a smaller F number so that more light can get in. 

To process the film negatives you have to open the camera and take out the film in a bag so that it is not exposed to the light. Next wind it into a reel, put it in a container with a kid on to make it light right. 
Use chemicals to fix the image onto the film. 
To develop the film first do a test strip to calculate how long to expose the image for. 
The longer it is exposed the darker the image will be. I desired to expose mine for 6 seconds to create the contact sheet. 

I chose 2 images to enlarge; for each one I did a test strip - for the stone and fir cone I decided that 6 seconds would be best because it gave a good range of tones from light to dark. 

To enlarge it - put the film strip into the holder in the enlarger so the your image is in the window. Focus the image so the image is sharp and fits into the piece of photographic paper. Time it for 6 second then put the paper into the development chemicals for 2 mins
Stop bath for 30seconds 
Fix for 5 mins
Wash for 10mins
Dry
