I have just started this practice of keeping notes on every exposure. I have a little black book that I keep with my camera stuff and I write down the date, the subject matter of the exposure (sort of), the subject brightness range, sometimes where I placed zone III and VII (like "bottom of tree trunk=III, white cow=VII"), and how many seconds or minutes I exposed it for. This really helped when I was trying to figure out the speed of HP5+ for me, and helped me close in on correct development times. One problem I ran into yesterday: I started an exposure around 6:30 pm and according to my calculations it was to be 20 minutes. When I came back 20 minutes later, the scene had changed a lot. I metered again and it was two stops darker in the shadows! So I figured a new time for that amount of light and averaged the two, which turned out to be 80 minutes. Went away and of course it got darker some more while I was gone. It was plumb thick dark when I came back. I developed that film tonight and sure enough, it was underexposed. I guess you could say the moral of the story is, don't try to make a picture when it's getting dark. But, that's when the wind dies down and leaves stop moving around. It would be nice if there was a way to figure exposure when the light is constantly changing. --shannon > > > > _________________________________________________________________ > Send and receive Hotmail on your mobile device: http://mobile.msn.com > > > _______________________________________________ > Post to the list as PLAIN TEXT only - no HTML > Pinhole-Discussion mailing list > Pinhole-Discussion@p at ??????? > unsubscribe or change your account at > http://www.???????/discussion/
