Fine art photography using photographic paper as the negative in antique cameras, vintage cameras and DIY cameras.
I use photographic paper instead of the glass plates that would have been used originally in the cameras from c1900. The paper is not sensitive to red light (orthochromatic) so produces an image with a "different' feel. The image produced on the paper is a negative image - back to front, upside down, light areas darken the paper, the darker areas appear light where the white paper has not reacted to light.
Some of these negatives are contact printed to make a positive print, whilst others stand as great images as they are.
Lots of advice on using photographic paper as film in this facebook group
