I'm converting several cheapie 35mm cameras to pinhole
cameras as gifts for my nieces and nephews (remove
shutter & lens, poke & sand pinhole in bit of aluminum
pop can). I want to put an exposure guide (a variant
on the old sunny-16 rule) on a sticker on the back to
get them started, and wondered of this sounded about
right to folks (I'm basing this on my own dabbling,
but my records aren't great (my exposure notebook got
washed!)(the focal length is about 40 mm, and I
haven't figured out an exact f-stop for the pinholes
yet).
