A friend returned some 8X10 holders to me and loaded a selection of different films in them, writing on each side of the holder what film was loaded there. Unfortunately, as I now discover having taken photos with these holders and having unloaded the film into tanks before processing, he was not accurate in his labeling. The films involved according to his labels are: Ilford HP5 and FP4 and Acros. I know what the notches for HP5 and FP4 look (or rather, feel) like, but don't know what the Acros notch is like, though I have searched the web. I can't be sure that the film that isn't HP5 or FP4 is actually Acros, since he uses a range of films besides Ilford and Fuji.

Can anyone help with a description or picture of an Acros notch?

My other problem is that I no longer know which film came from which holder, so that I suspect one non-HP5 film has been exposed at 400 ASA, but cannot tell which one - but that's another story...

Thanks for any help
