Speed of Kodak T-MAX p3200
- As well as I know, 1000 is closer, but 800 is within the uncertainty. The actual ISO value depends on which developer you use.
- See: http://www.kodak.com/cluster/global/en/professional/support/techPubs/f32/f32f.jhtml
- and: http://imaging.kodakalaris.com/sites/prod/files/files/resources/j86.pdf
- even more, note that there are two different films with almost the same name, and both with the TMZ code. (This is true for TMX and TMY, too.)
- But mostly, the characteristic (D-H) curves for TMZ (both of them), and Delta 3200 are not usual. They don't have a real straight line section, and so the ISO measurement isn't quite as good as you might hope.
- Even more, this film has exceptionally poor keeping qualities. Even frozen, there are enough cosmic rays to fog it. If you have any to use, EI 400 is probably the best choice. Gah4 (talk) 17:45, 11 October 2016 (UTC)
There is an unsourced tag for the section Digital camera ISO speed and exposure index. Seems to me that it cites, among others, the ISO standard itself. Now, it isn't so convenient in that you have to pay for the ISO standard, but I don't see how it can be called unsourced. Gah4 (talk) 17:02, 11 October 2016 (UTC)
- That ref is in the 'The ISO 12232:2006 standard' subsection. I intended the unsourced template to relate to the section before that, but did not know how to indicate that using such a template. -Lopifalko (talk) 17:31, 11 October 2016 (UTC)
- Yes, the subsection is within the section. The part before the ISO 12232:2006 standard subsection is, as well as I know, the introduction to the section. That is, an overview of the following subsections where the actual details are spelled out and referenced. I am not a Wikipedia expert, but I believe that is reasonable. As above, though, the fact that the ISO standard isn't free to look at is inconvenient. (There are some standard sites that now allow free access for non-commercial use.)

ISO in digital cameras
It would be good to have a separate article on ISO in digital cameras, as it is so widely misunderstood mainly because of its heritage and meaning in film. — Preceding unsigned comment added by Chrisvdberge (talk • contribs) 12:07, 5 May 2017 (UTC)
