RE: [Digital BW] DSLR sharp? -- was How tiny dots determine real resolution in a B&W ink print

2008-09-28 by E Neilsen

David, Why repost your first comments? That is the point. An image needs to
progress PAST the point of capture. It will be processed. I don't dispute
that having an accurate way to measure is a good thing, but the reality of
how much happens after that also needs to be taken in to the discussion. 

 

Is there a digital workflow where NO sharpening takes place after capture?
If not, or not commonly being used here, then this optical illusion that you
refer MUST be a part of the discussion; and as you point out, not such a
straight forward thing to measure.

 

So as far as we know, what brave independent tester is taking that on?

Post-capture sharpening is an optical illusion, so testing it is not 
as straightforward as counting visible lines per inch. I don't believe 
there would be any valid method other than visual evaluation, at a 
fixed distance, using side by side prints with the same size, image, 
media, inks, printer, profile and lighting . But then; the results 
would really only tell you about that combo, and might well be 
different for other combos.
