Okay, I'm trying to do a film speed testing, but the two sources I have, do it in increments/decreases of 1/2 or 1/3 stops. Now, I'm a newbie. 1/2 and 1/3 stops may not be complicated to you more experienced fellows, but they are to me, a beginner soul. Can someone please give me the easy version of the film speed test? In whole stops? None of this half or third business? These are my requirements:
I'm testing my large format Sinar F2 (obviously sheet film)
I have access to a densitometer
I have a gray card (I know there are ways of doing this test without one, but I want to do it with a card)
I think that's it. I can't think of anything else. Can someone give me the easy version of the film speed test? Thanks.
