English made Kodak, another of their prodigious and
inexpensive cameras. The Diodak shutter has an interesting exposure guide
feature whereby the user lines up the lighting conditions with a shutter
speed. Under "brilliant" conditions it suggests an exposure
of 1/25th sec. at f/16, which would indicate that the film speed was in
the order of 25ASA.
Film makers who also made cameras often
used the inside of the camera as an advertising opportunity and
you will often find such labels. Sealed away in the dark, the inks
are protected from fading and their brightness is often in stark
contrast to the dour exteriors. Here is the one from the back of
this Kodak camera.
