Joe,

When I learned that somebody as proficient as Yosuf Karsh was impressed to learn about the f-stop printing method, I understood that it has merit. He was no slouch when he visited Gene Nocon's studio to find out how the heck he could have the results he had.
So I tried it, and it works for me. It's second nature today, and I thank you for bringing your experience with your students up for us to see.

I think that it's good to sometimes examine what we do, to see if we can improve. So I will always listen to those with other ideas. But I do not take very kindly to those who categorically declare something to be wrong just because we don't do what they do. That is hard to swallow and completely unnecessary.
