what colour space

[MitchellB]

I have the 20D

What colour space would be best? What do you use? Why?

[kawter2]

I always use AdobeRGB in the camera, then if I am printing at a photo lab that does not accomodate, or if i uploading to web, I have an PS action and batch convert to sRGB.

Adobe's is larger so it shows a broader range of color, the problem is that a lot of devices can not accomodate it. You can always downsample to sRGB if neded

SRGB, because some people say to use one and some say to use the other. I had to pick one.

Adobe RGB has a bigger color gamut. As Kawter said, it's better to have too much information that can be reduced than not enough

[Hellashot]

Doesn't really matter. Your print space being aligned to your printer print space is what's most important.

What about ProPhoto RGB?
Am I the only one?

I use RAW so it doesn't matter. The PS color space I use depends on what the prints are for - since most of my pic go on the web and few get printed, I often use sRgb.

If i'm taking JPGs they're usually destined for the web, not print, so i'll take them on sRgb.

Someone should add "it depends what i'm doing" to the poll.

I now always use Adobe RGB, as has been pointed out, you can always downsample to sRGB.

Steven. At least two of us. Maybe I'm looney, but my workflow for KEEPERS is .CR2 RAW to 16-bit Prophoto RGB in ACR. In ACR, make basic tone, white balance, contrast, never saturation or sharpening. Edit in PSCS, then Capture Sharpen with PK Sharpener. This Prophoto 16-bit TIFF becomes the archive. Files can then be tasked to 8-bit sRGB for web or 8-bit aRGB for printing with automated PS actions. Why....?
1. Because there is information in the Prophoto that no one can even deal with today, but they may in 5, 10, 20 years. Why not keep it? And 2. Canon inkjets print color far beyond the range of sRGB gamut, particularly the i9900, with intense yellows and greens. Like here is a workplace shot you will not care for:

BUT, Prophoto to aRGB has retained the subtle yellow of the microscope light against the green sick Bent grass turf sample from a putting green. This was handheld in bad light in a fine turf diagnostic laboratory. And I don't think I would have ever retained the subtle greens/yellows without Prophoto to aRGB. The print looks stunning. J
