Accurate focus through enlarger

[Dinesh]

Please don't cloud the water here, as I appreciate the value of stopping down, but not checking focus at one stop down.

Yes, a guy who prints professionally for a living is more than likely trying to "cloud the water".

Question: Are you currently professional printer, and by that I mean someone who prints other people's images for a living?

I think he lost interest in this thread after I tried three times to explain why there is possible value in checking focus at the working aperture.

Check his history, he'll be back.
