View Full Version : sRGB vs AdobeRGB

When I save my raw G3 files to tiff, I assign the sRGB colour space. Since the AdobeRGB is a wider colour space, would it be advantageous to save directly to that?

Or, when I import into Photoshop, convert to AdobeRGB as my working space, do my workflow, then back to sRGB when saving?

ANy help would be appreciated
Thanks

drisley,

There's not much point in converting from sRGB to Adobe RGB. Although Adobe has a wider colour gamut and includes colours that sRGB doesn't, you can't get those colours back even if they were there in the first place.

If you are happy with your pictures from the G3 using the sRGB profile, I would just suggest changing your default working space in PS to sRGB.

If the G3 is capable of a wider gamut then sRGB - perhaps, by using a custom profile - you may gain by assigning the custom profile, then converting to Adobe RGB.

saving directly your file to (converted) srgb in my opinion you loose all the raw workflow benefit!
srgb is a small gamut gamma 2.2 space for the Web.
Convert your image to this space before posting to the web or to print if you do not have specific printer profile!
The best choice for me is to stay in a big linear gamut working space with your camera profile or whatever profile assigned, do all your needed adjustement in 16 bit space then convert to adobe 1998 8bits to make your latest adjustement (8 bits compatibility).
It's not because you don't see a difference on your screen that the print would be the same!
As Roger says you cannot recover what you loosed at the first place (if clipping occurs from a large space to a smaller one).

Thanks,

From what I've been reading, the G3 natively uses the sRGB colour space...
