A Dev -3 does not always mean 3 minutes less.

Each - increment (or + increment) is a percentage is a percentage of the original Dev time.

Some people do 10% increments, some do 15% increments and some do 20% increments.

And some do sufficient testing with a Stouffer step wedge at different dev times to enable plots of characteristic curve at each dev time and can then obtain (1) a close estimate of the dev time needed each expansion/contraction and (2) the amount of additional exposure time needed to preserve shadow detail when using contractions. A densitometer is used for these tests to read the plot points from the separate negatives of the step wedge.

I think I've seen some of these before, Nana, but that doesn't take away from their impact. I particularly like the first one - Arribas - and like several other of your images, it reminds me of some of the landscapes that one finds in a Dali. It must be something to do with the Iberian coastline, I guess.

Thanks, David

probably, I already posted these photos, the reason is that I don't have new stuff, I'm to lazy, at the present time, I think I'm really geting old!!!!! ;-)

As to Dali, I never thought about that, this a perfectly normal sight around here.
