Ok, haven't taken a picture yet with it (paint drying...) but, talk about CHEAP!
11x14 x-ray film ($30 for 100 sheets= $0.30 per image!!)
Cardboard box, tape, flat black paint, FREE courtesy of my parents.
20cc's of Rodinal ($13/ 500ml bottle = $0.52 per image!!).
$0.30+$0.52= a whopping $0.82 camera!!! In 11x14!!!!!!
Now I just need to actually take a picture...
In the mean time...
This is my first pinhole camera so I hope I did the calculation right, it's a bit confusing to "simplify" for a guy like me...
