Re: You applied color space instead of converting.

OK I see what you are doing. I downloaded the original and opened in PS. It's tagged as sRGB and looks green and washed out. I "applied" (not converted) the proGB color space and the image looks like the preview/correct. I'm not sure what workflow you are using but you have to CONVERT to a profile, not assign them.

I uploaded the "fixed" file after I assigned proRGB and then -converted- back to sRGB. You will see now the click through original looks fine. (I downsampled it to save upload time).

Nice catch Ed and Stacy. It never would have occurred to me that someone assigned a profile rather than converting.

It's just one of many problems working outside of sRGB that can happen.

And honestly, unless you really understand color space (and know why you really need a wider color space for a particular image), you're probably better off capturing and working in sRGB. Wider <> "better". For most images, even when used correctly, the difference is pretty subtle but the problems caused by incorrect color space use is not, as you have found out.

I disagree. Learning the difference between assigning a color space, and converting to a color space is not rocket science. Work in a wide color space; convert to sRGB when going to the web.

That is over simplifying the problems that can happen working even in aRGB, much less something like proRGB. A big one is VERY few monitors can display outside of sRGB and most can't even cover sRGB, so editing becomes a problem. You can't see what you are doing. You at least have to be checking for -out of monitor gamut- colors often to even have an idea of what is going on that you can't see.

Also, as the color space becomes wider, the chance of posterization increases.

And last, most places you send a file to be printed want sRGB files. Anything viewed or shared online needs to be sRGB. Unless you have had a custom profile made for your own printer, most "canned" profiles don't print far enough outside of sRGB for it to even be visible in the final print.

The only time I work outside sRGB is when I have an image I know has a color "being clipped" by the smaller color space (usually is something really brightly colored like a yellow flower) and I'm going to print on my custom profiled home printer. Then I pull an aRGB file out of the RAW, edit while checking the -out of monitor gamut- colors to make sure then they aren't also too far out for the printer profile gamut to deal with, and then print. Yes, there is a subtle difference in the final print but it isn't earth shattering.

IMHO there are just too many down sides to using a large color space vs the gain you can see in -any- final output for most images. For example, the image the OP posted is no where near the edges of sRGB. In my experience, most of the images I capture aren't either. Most people work in a large color space because of the belief "bigger is better", it really isn't true for most photographic uses.

I know this flies in the face of popular opinion but then again, I like shooting jpegs too *gasp*
