Cool. Got any shots of the inside? How did you calculate the curvature of the film plane (or did you)?

Thanks guys
the curvature radius is just about double the focal length.

I will post some saps of the inside sap Colin

That image looks great. I could ballpark it but to save me the math, what size is that neg? I was looking at your photobucket site,it looks like you shoot a few interesting cameras, such as stereo pinhole!!

Thanks for you comment. I must finish off another one of my homemade cameras, it's  stereo pinhole made from a couple of 35mm canons

The image size on the curved plane is 6 x 19 cms
