[ARC5] WW II Aircraft factory pictures

[J. Forster]

My understanding is the rise of the EPA was a big part of the issue. They
all but killed E-4 and E-6. Probably Kodachrome also.

I do not think that 'going digital' will eventually be seen as a 'good
thing'. You can still get something from even a faded picture, but not
from an ureadable HD or Flash card..
