[filmscanners] Re: Are there multiple versions of SRGB?

["Ellis Vener" <ellis@ellisvener.com>]

sRGB may have a strict technical definition but different companies 
apply it differently. Bruce Fraser & Andrew Rodney in particular have 
pointed out that what Nikon, Fuji and Canon (to point out three big 
examples) call sRGB or Adobe RGB in their cameras isn't quite exactly a 
"pure" implementation of these colorspaces. All cameras or scanners are 
in fact going to produce device specific interpretations of color. The 
way to get around this is to go to raw or NEF captures capture with as 
wide of Colorspace as the device will produce  where the camera is 
doing no (or in all probability very little) colorspace management.

The downside to this approach is that you have to do a lot more work. 
That works fine in some situations but in others, it doesn't.

You also have to be working on an accurately calibrated and profiled 
monitor to actually see what the true colors of your captures. The 
Adobe Gamma utility or even the Apple Colorsync utility  won't get you 
to an accurately calibrated and profiled image on your monitor ,but 
given the high degree of knowledge on this list I assume everyone 
already knows that.
