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).

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
