RGBs or RGB

Not clear on which color space is best to shoot in, RGB or RGBs ?... My color lab tells me to use RGBs... I would like to hear from you all about your experience....

My color lab agrees with your color lab -- When I do my part on the user side of the camera my prints look great -- Canon also suggests that I shoot in RGBs -- All that's good enough for me

Not RGBs . . . . it's sRGB. sRGB is the colorspace that is used for normal computer uploads to the internet and to emails around the world. These view most accurately for this purpose. But the other RGB's such as Adobe RGB or Prophoto RGB have much larger color spaces and should be used if your printer supports larger color spaces with the number of colors it can represent.

Use Adobe RGB to shoot and convert to sRGB in post processing for printing and posting online. In fact, most online providers convert images to sRGB automatically.

Do you shoot in RAW? Because if you do, the question of color space is not relevant until you perform a conversion to an output file format (TIF, JPG, etc).

UHH doesn't, which is why you will sometimes see a very drab thumbnail, but when downloaded, it becomes vibrant, saturated and bright. Ever since learning this tidbit right here on UHH, I'm trying to educate posters one pic at a time ...most online providers convert images to sRGB automatically.

Thank you.

Hi Canon... why does my Canon7D offer a choice of sRGB or RGB, If shooting in either doesn't make any difference? Would it be better to shoot in RGB and then export in LR for print sRGB?

It offers the choice for the in camera created .jpgs. If you do not save .jpgs from your camera (meaning you shoot RAW only) it has no effect because a "color space" is not embedded in the RAW file. So if you are a photojournalist who delivers your jpeg images straight from the camera to your agency then this is where you choose the color space in the jpegs for the publisher.
So, if RAW from camera - no difference.
jpeg from camera - embeds the chosen "color space" in the jpeg.

My two choices are sRGB or Adobe RGB - I use sRGB because of the commonality.

It depends on what your intended use of the images are! sRGB is very limited, but sufficient for web display!

See MichaelH's response, above. To your question, if you captured in JPEG, only, then yes, shoot in Adobe RGB and then export from LR, for print, in sRGB. For the RAW files created by your camera, it doesn't matter for the color space setting as a RAW file doesn't yet have a color space.

If you shoot raw, you can have a wide-gamut workflow, until final output. That is less likely to generate undesirable results during editing. ACR/Lightroom use a color space that is similar in size and depth to ProPhoto. It doesn't matter what color space you use if you use raw files.
As has been stressed above, if you use jpegs, then I'd use Adobe RGB, which is larger than sRGB. I only use sRGB for final output, after ALL the editing is completed.
Color labs don't care what you shoot, or what you use during editing - they just have their equipment optimized for sRGB files, so that is what you give them.

When shooting RAW there is no embedded color profile. Photographers have a tendency to use wide color spaces like ProPhoto or Adobe RGB during editing. It is said, nobody can see them, that both wide color spaces have billions of colors. sRGB has millions and nobody can see them either.
All professional labs, that I know of, work with sRGB and none of them will accept a RAW file with those wide color spaces. If you have a RAW file edited lets say with Adobe RGB you first have to converted to a JPEG and sRGB before the lab will accept it for printing.
Since RAW has no embedded color profile I always assign sRGB to my files. Using JPEG images no issues.
