Iso film speed ????

[MattKing]

Considering how truly international Eastman Kodak was in its heyday, with many many international subsidiaries manufacturing and processing and marketing unique and different products throughout the world, it is weird how George Mann seems to feel about the rest of the photographic world.
I wonder if he would have refused to use Canadian Kodachrome - it did, after all, have both English and French on the cassette.

For the record, I am staunchly anti globalist, not blindly pro American.

George, please take that stuff elsewhere. Nobody really cares about your personal bias nor is it pertinent to this discussion bb

Then you would not have done well if you had worked for Kodak in its heyday.

Badly off topic I admit.

I have been most uncomfortable over the last 30 years as the world changed for the worst.

To bring this thread back on topic, I will say that I would normally champion a universal standard that made sense (and perhaps ISO does).

But since the mad push to globalization has ruined so much in this world, I can't help but to feel most negatively about it, especially when such a push has led to there being precious little left of photographic value in my corner of the universe.

... so you don’t know this standard, or understand engineering standardization, but have an opinion. Classic.

This may be the single most tenuous connection between cause and effect that I have ever seen...and super unfortunate that someone would strip themselves of all agency as a result. Being victimized by nameless "others" seems to have become an unfortunate fad in our society.

Wrong on both counts. I confess that my ignorance of the matter was self induced.

I see things that others seem incapable of. Let's leave it at that.

Some variations between brands in the way they display sensitivity.
Agfa (Ultra 100, Optima I 200), Orwopan 25, Orwo-branded (Konica) CNS 200 (photo 1), Polaroid 669 (Photo 2), Kodak (Old Ektachrome, Photo 3) : all use "ISO (ASA)/(DIN)" on the boxes.




On the 35mm rolls: Agfa shows "(ASA)/(DIN)" without prefixing with ISO, the Konica shows "ISO (ASA)/(DIN)"


On the 120 rolls, both Fuji and Kodak only show "ISO (ASA)", no more DIN value (maybe because these are newer, and it has become customary for people to drop the DIN value and forget about it given the influence of digital cameras).


My ¢2 about forgetting the DIN in what is a standard that should be strictly applied: I do regret the trend of forgetting this scale, if only because lens f-stops are often split into 3 clicks, which (at a given illumination and shutter speed) correspond to one ° DIN unit each; in addition, the ASA scale was made for easily multiplying and dividing by 2 but that meant that some rounding was necessary, and the approximations not always consistent (sometimes up, sometimes down): add 1/3 stop sensitivity to ASA 50 should give 50*2^(1/3) = 63, not 64, 2/3 more above 400 should be 400*2^(2/3) = 635, not 640.. These are nothing important at all, but just get annoying when trying to create exposure plots as it becomes impossible to predict how the rounding is done (must use a table).

I have a hunch that the labelling differences may also be regional. As an example, in markets where DIN speeds were more commonly used, the use of ASA or DIN in labelling may have been different.
I would love to see what the ratio between US sales and International sales was for Kodak was in their heyday.
I would not be the least surprised to learn that the USA market was simply a small but important portion.
