AuthorSubject: ACR2 CONVERSION QUESTIONS   [Go to Bottom of Page]
Mark Tomalty
Posted on Mon Mar 22, 2004 12:13 PM



I have a couple of questions about RAW workflow issues I was wondering if anyone
had any thoughts they'd care to share.

1-Saturation-Knowing that,at times,I would desire a final image that has a
fairly strong saturation I was wondering if there is an advantage,or are there
any disadvantages(as in file degradation),to performing this move on the RAW data
in ACR2?

2-Vignetting Slider in ACR-should there be any file degratation relative to the amount
of correction (say '+25' vs. '+75') applied in extreme situations.

3-Chromatic Aberration-If a given lens requires a CA correction under conditions
that highlight the problem (dark edges against light b/g,for example) would there
be any advantage(however subtle) to use the same CA settings with the same lens in
all conditions?
While it might seem unusual to apply CA corrections to an image that is captured in
conditions that aren't necessarily problematic my thinking (or not!) is that since
a lens might require a correction for this problem in some situations why
shouldn't it require it in all situations given that the lens/optical components
are the same?
Does CA have any direct bearing on image sharpness,specifically fine detail?


Thanks,
Mark
