Film Test Results

Yes I did. Minus 5 was 1/3 over FB+F. So that means Minus 5 is Zone 1 and the ISO should be 200. Is that correct?

Thanks for the help.

That all seems correct.

Most people think of ISO as a fixed property of the film, so your 'exposure index' would be 200, but everyone knows what you mean.

Now that you have your EI, one way to get your development is to shoot a Zone VIII at EI 200. Then print that (at your min exposure for max black) with part of the paper covered. If it is just off-white your film development should be good for printing most scenes on multigrade paper.

IC and others thanks for all the help. I don't have an enlarger just yet, I am undecided about wether or not to wet print or get an inkjet. I really want to sell off all of the digital stuff and go full analog but that is another subject for another day.

2) Use your exposure meter and meter through the negatives and pick the one that blocks light 1/3 of a stop more than a clear frame

OK, I did that. My reading for ISO 250 is 1/3 stop on my Gossen Luna-Pro. With a digital meter (Minolta Auto Meter IV), I get 0.3 for the ISO 250 negative and 0.4 for the ISO 200 negative. I guess my speed for HP5+ in Xtol is ISO 250.

Can I do the same/similar thing reading negatives with an exposure meter to find my developing time relative to Zone VIII? How many stops above fb+f or the Zone I exposure on the exposure meter should I be looking for?

Thanks for all your help.
