What do you do with 6x9 slides? Do they even make projectors that big, or do you just have to hold them up to the light and look at them in the positive-film equivalent of a contact print?
I am *not* wondering what slides from my Foldex 20 would look like. Nope. :-)
Nope, just scan them and enjoy. The Clack is a ridiculously simple camera to use. Just 2 options, (overcast/sunny) and (time/bulb). That's IT! Don''t forget to pay attention to the proper # in the rear red window (there's only 8 shots to a roll), and you should do fine.
Don't expect too much, it's not in the same MF league as Rollei, Hassy, Fuji, etc.
If the lens doesn't read "ZEISS", then it just isn't.
