Hey, guys, do you understand that RAW files have no colorspace? That’s part of why it’s called “raw”—it is the raw sensor data.
I haven’t looked at Nikon raw files. It’s possible that it stores “sRGB” or “AdobeRGB” depending on how the camera was set, but this is just an advisory. The sensor values are converted to a colorspace by PhotoLab using algorithms specified by the “Color rendering” panel. The target colorspace is always AdobeRGB, because that is the internal colorspace of PhotoLab.
As with any program, the internal colorspace is converted to the monitor’s colorspace for display. Ideally, you have a calibrated display and you would always choose “Current profile of the display device” for the display preference. With a calibrated display, what you see (as long as it falls within the display’s gamut) is what you should get. You won’t see colors that fall outside the display’s gamut—it’s not possible.
I tried exporting a JPG with an ICC profile of “sRGB” and it does look like the sRGB option does not write out the color profile. Perhaps this reflects my ignorance—maybe files without color profiles are treated as having an sRGB color profile, so no color profile is needed.
I tried the “Original” option and, despite what kokofresha said, it wrote out no more than when I chose “sRGB”. My camera setting is “sRGB” which I completely ignore since I shoot only RAW files.
Selecting “AdobeRGB” or a custom profile embeds a profile.
I wrote out my image using the ProPhoto colorspace. I then viewed it using a program that honors the color profile. All versions of my JPG looked identical—the sRGB version with no profile, the AdobeRGB and the ProPhoto.
As one final experiment, I read the ProPhoto JPG and saved it in Photoshop as an sRGB JPG. Photoshop did include the profile information, so I’m not sure why Photolab has decided to not include it.
Geno, I don’t know why you were having a problem, but perhaps you were viewing with a program that didn’t know how to handle a file without the full profile. Choosing an ICC profile for output is a good choice. But I did want to clarify that:
- RAW files have no colorspace.
- PhotoLAB always converts stuff internally to AdobeRGB
- If you’re shooting RAW only, the choice of sRGB or AdobeRGB in the camera is immaterial.
