How to design your pinhole camera

If you know the focal length of your design

  1. Enter the focal length and press calculate for the optimal pinhole diameter and coverage diameter
  2. Check that the coverage circle is large enough to cover the negative
  3. Enter the actual pinhole diameter and press calculate for the fstop
  4. Enter the film dimension and press calculate for the angle of view, 40 is normal, 50 wide angle, 20 telephoto
  5. Enter the film speed (ISO/ASA) and press calculate for the sunny 16 exposure time

Or you may do one of the following and then perform the above steps

  Enter the pinhole diameter and press calculate to get the optimal focal length
  Enter the focal length, then the fstop, then press calculate to get the pinhole diameter for that focal length
