How to make a Photogram Test Strip:
A photogram is an image that is created without a camera or a lens, by placing objects onto a piece of light sensitive paper, in a darkroom and by using light (preferably from an enlarger) to cast a silhouette of your objects, this creates a unique image.
A test strip is used when you're trying to figure out how long to expose your light sensitive paper to a light source for, to create the best image.Remember that the paper is highly sensitive to paper so you need to be in a darkroom where you can work in safe light conditions.
You'll need:
1. Objects of your choice
2. An enlarger
3. Light sensitive paper
4. Piece of cardboard (preferably bigger than the paper you're using)
