ACR - ProPhoto RGB

Diff · July 22, 2008

I'm not familiar enough using ACR to know about "Space" & "Depth." I'm pretty sure the two best choices are: Adobe RGB & ProPhoto RGB. What are the preferences under these circumstances:

1) Global work in ACR & import the image as a Smart Object to CS3.

2) Returning the image back to ACR for possible fine-tuning.

3) Image back to CS3 to flatten image & save as jpg for commercial printing.

Thanks!!

For 1 and 2, I use ProPhoto. (But for many images, a straight sRGB workflow will be fine also.)

I then save a final jpg in sRGB 8 bit if going up to the web, or in aRGB if I am going to print it on my own 8 ink inkjet printer ( which has a larger gamut than sRGB )

Great and thanks for the clarification.

ALL the processing in ACR (and Lightroom) happen in a ProPhoto RGB space (linear encoded). So that's what's happening under the hood regardless of what RGB space you eventually encode the exported data with FWIW. For that reason, I choose ProPhoto RGB. There are others of course:
