After spending the better part of a year thinking about designing a tiny film projector I am beginning the process. I know the basics of photography but I find it very difficult to calculate what kinds of lenses I should use for such a unique application. I would be very grateful for any advice from this group. I am lucky to have found stack echange :)
My design idea:
- 5mm square picture made from 35mm positive film (I already have a prototype image)
- LED projector light
- Lenses to project the image from 1 to 5 meters away
- Cost is an issue so simple solutions would be preferable
If anyone can help me understand lens shape and positioning it would help me a lot.
