I was just reading about f-stop printing, but it seems to require a timer than can be set to fractions of a second, right ? (mine can't)

Bill, that is a great quote ! it's got me thinking...

I do have a question (for everyone). When you find the min exposure time to get max black using the clear bit of leader, do you use that as the starting time for your test strips ?

Oh, and I too have a half frame camera, a Ricoh Auto Half E. I think I have the negative carrier for it too

Many thanks everyone

(I will post an update after my next print session, hopefully one night this week)
