Photogram Positive and Negative

There are a few things that you need to do when making a photogram. You arrange the objects onto the light sensitive surface of the paper. Once happy with your design turn on the desk lap to expose the paper. Depending on the brightness of the lamp you will need to expose your photogram for around 2 or 3 seconds. I did mine on the F8 F-stop for 2 seconds. You then run your photo through the developing chemicals and you have a picture.
