I am saying that because wherever review I find in the internet they say Fomapan 400 is actually ISO (or better perfomaced) at 250 to 320 depending on the developer (250 for Rodinal). And I have read many posts complaining about issues with this film exposure and replies explaining it is because 400 is not the real ISO.
After reading that (in different pages) I was surprised I got a good exposure. And I was wondering if the data in digital truth is actually adapted to develop it at ISO 250, or if it was because I am used to over expose a bit so I just got luck.
This is a example of what I got: http://www.marciofaustino.com/upload...08865_orig.jpg
