Interesting 1939 vintage Kodachrome booklet ...

[dmr]

It's a very interesting read, and does go into some technical details ...

One thing I found as odd/interesting is that on their diagram of the exposed positive, the colors are clearly shown as red, blue, and yellow, not magenta, cyan, and yellow.

I've only seen the first couple of pages so far (17 meg file!). Thanks for posting the link, looks very interesting.

18 exposure rolls?

Very interesting. Thanks!

LOL, I missed that on the first reading. That's a new one on me!

I remember 20 exposure rolls very distinctly. I've also seen 12 and 27 exposure rolls of various films, but never 18.

dmr, thanks for the link, I used plenty of Kodachrome in the 50's and 60's. It was ASA 25 then. But before that they had ASA 10. I'm sure it is mentioned in that booklet (which I haven't read completely yet). I did find this Kodachrome with my father-in-laws things from December 1936 (I did color correction, but some of the early 40's did not need CC):



I'll throw a 40's in too (not mine):

Wow, that's better than many 1980s vintage slides and prints!

One thing this just reminded me of, and it may take me some digging, literally, to find out, is that our family may have some 1950s and 1960s vintage Kodachrome that I didn't even think of.

When I was young, we had a movie camera, and I'm sure that most of the movie film of that era was Kodachrome. (I do remember my one brother having to search to find B&W movie film in the mid 1960s.) I think some of these old films may be in my stepmom's storage locker in the cellar of her building, and next time I'm out there (quite possibly not until the holidays) I'm going to see if I can find them.

If they are indeed Kodachrome, they may be very well preserved.

My mom's 4x4 slides from c. 1960 sadly are not Kodachrome;
mostly Anscochrome, I guess. Many have faded and changed colors.

dmr and Chris, Good ole Kodak, my Ansco, 3M, DynaChrome, and Technicolor slide show some color changes. The EktaChromes and KodaChromes seem like yesterday. Here is a bad scan but good color of a DisneyLand slide taken (by me, IIIf) in 1964 or 1965:



or maybe I didn't focus correctly.
