Thank you guys for contributing your answers !(posted 8035 days ago)Anyway, iso 25 is "only" 1 stop more than iso 50, so it doesn't result in such a huge overexposure... I agree with John, and I guess that processing it the way I use to will give me a quite printable result, and anyway, I prefer to adjust my printing conditions rather than my film developing ones... perhaps I'll get a more contrasty negative but why use variable contrast paper if you don't use its variable contast properties ?
I remember having shot the 3 first frames of a roll of HP5 at iso 25 (the remaining frames at iso 400) : I processed the stuff as usual, and I still managed to acceptably print these 3 very overexposed (4 stops) and contrasty frames...
What I'm interested in is to understand why some of you will shoot Pan F Plus at iso 25 rather than at iso 50 ? I just can't get to understand why ! (whereas I understand the interest and disadventages of pushing a film).
What about Tetenal products in the USA ? You don't seem to have an easy acces to them, whereas they are very common here in Europe... I couldn't find a lot of tetenal-related discussions on this forum... I am very pleasd with them : I use "Negafin" and "Ultrafin Plus" as film developers, and "Work" variable contrast RC paper (the cheapest I could find).
Once again thank you for answering me... see you ! Eric.
