ISO
Just to be sure, DX mentions speed but not ISO? This distinction is important for films like TMax 3200, which have a recommended EI different from the ISO value. Gah4 (talk) 11:53, 19 July 2019 (UTC)

From my understanding, the DX code on those films labels them at their EL of 3200 ISO equivalent, the technical ISO of the film is ignored. I could be wrong! Anymouse (talk) 11:51, 6 July 2020 (UTC)
