When I apply the ideal exposure for colour slides on Fujichrome Sensia 100, converted to 200 ISO, to Agfa Scala 200 (black-and-white transparency), I have found that the black-and-white transparencies come out too dark and gloomy. The brighter exposures of the same subject produced better black-and-white transparencies.
Is it generally the case that you need to overexpose black-and-white transparency more than colour slide film? With Fujichrome Sensia 100, you often even have to underexpose slightly to get strong colours. With black-and-white transparency, it seems to be the other way round. If you don’t want the transparencies to turn out dramatically dark with very black shadow areas, a more generous exposure is probably called for.
Does anyone have any thoughts on this? I have very little experience with black-and-white photography and am used to colour slide photography.
Perhaps someone could also compare Agfa Scala 200 and Fomapan R 100 – do they both require similar exposure settings?

Hello,
I used to expose the Agfa Scala at 200 ISO when I had it developed using the Scala process. The results were always excellent. Nowadays, I expose it at 125 ISO and perform its development using the Foma reversal kit, which also gives good results. I expose the Fomapan at 100 ISO and perform its development using the Foma reversal kit as well.
Best regards,
Christoph

Hello bahnjens,
I can confirm your observation. However, I only noticed this myself after I started developing SW transparency film myself (I tested the development process) and compared it retrospectively with the Scala.
With some subjects, it’s better not to expose the Scala at 200 ISO, but rather to use a slightly higher ISO setting.
