Thank you! Great point about the film. We would end up wondering why my father took pictures in the 90s of featureless amorphous blobs.Casual Observer wrote: Mon Apr 10, 2023 4:35 pm Think CVS does but I also read that undeveloped film may not have held up.
More likely you would wonder why he took all blank or all black pictures. The film itself is made of non-biogradable polymers, so if left in sunlight it will take hundreds of years to degrade (decompose). It's the emulsion, the light-sensitive chemicals, that produce the image. Those are volatile chemicals that will evaporate after a few years. That's why film packs have a 'develop before' date printed on the box and probably on the label on the plastic shell.Ice Cream Jonsey wrote: Mon Apr 10, 2023 5:42 pmThank you!

you worked making film for Kodak? Tell us more.Ice Cream Jonsey wrote: Tue Apr 11, 2023 11:50 am Setting aside the fact that I worked one summer surrounded by nothing but emulsion for Kodak, the fact that my phrasing was something you still felt the autistic need to incorrect me about is... well, expected.
Photography supplies are very light sensitive. So much so, that Kodak was getting complaints about contaminated photo paper having white spots. They checked the dates and someone figured out what had happened. In the 1950s and early 1960s, the Defense Department did A-bomb tests aboveground at Alamagordo, New Mexico. Prevailing winds would carry the fallout as far northeast as Rochester, New York, and the residual radiation was strong enough to contaminate photo paper. This needed to stop, it made customers unhappy. When they informed the government, someone realized the patterns of those white spot images would be very interesting for other countries to allow them to discover what the blast size was. So, executive management at Kodak was 'read into' the secret testing plans, and from then on was told in advance of the date of each test, and when the fallout would reach them so that they would know not to manufacture photo paper on that day.Ice Cream Jonsey wrote: Tue Apr 11, 2023 6:10 pm It was just a summer job, my dad worked there so I could get a job collecting barrels of it.

Wow, very informative. I never would have looked that up and you brought it to us.Tdarcos wrote: Tue Apr 11, 2023 8:32 pmPhotography supplies are very light sensitive.
