sRGB vs Adobe RGB

Hi all,

Can someone out there explain the difference between these two colour spaces. Which is better etc and what are the pros and cons.

Cheers

See similar threads below but the short answer is a) if you don't know very specifically why you might need Adobe RGB use sRGB and b) unless using either sophisticated home printers that accept aRGB or a pro lab that does; use sRGB - most labs like Costco etc. won't take aRGB.

Adobe RGB has a wider gamut.

The adobe has a greater range of colors and your photos will look better printed. sRGB with fewer colors does better with websites displaying your colors. A few years back Kodak entered the fray with their Prophoto that has an even greater color range that helps with printing.

Adobe RGB as Rey pointed out has a wider gamut of colors, which means that they can more accurately represent the true colors of your photos both on the computer and in print.

If you don't have a specific reason to use Adobe RGB, use sRGB.

I think it's simplistic to simply tell people that wider gamut is better and will look better. There's ample discussion of this in prior threads but unless you use and understand colour management very well I doubt there's benefit for most - certainly none if your photos are destined for the web or for most non-professional print services.

Printing aRGB photos on a non-aRGB printer will look washed and colorless. Normally, the only time most (not all) people will want to use aRGB is for print magazines, etc. Now, if you're shooting and are not sure whether you will end up needing aRGB or sRGB, then shoot aRGB and convert to sRGB in post-processing.

Shoot raw and pick whichever you want later.

If you shoot RAW indeed you can use whatever you want later..
But that does not answer the question of what to output from your RAW converter....

If you want to though, you can always output your Tiffs in AdobeRGB, then work in PSCS in AdobeRGB workspace..
This means you preserve more of the RAW files color while working with the files...
Then when it's time to print you can either print directly from the ARGB file if your printer allows it,.

Or if you need to print SRGB, you can simply convert to SRGB,. and print. You lose nothing doing this (as compared to starting out SRGB ) in fact you gain, but doing your post work with before the SRGB conversion..

You can't however convert to ARGB from an SRGB file without already having lost some color info.

Why not export in ProPhoto then? I'd say it's the right thing to do for the pictures you are going to spend significant amount of time in PP. Export it in 16bit ProPhoto, PP it and save. Then when you need to "print" it for any type of media, you just resize and convert to corresponding profile, but your original is always in best possible quality.

Have a read here, or in a few of the links from the link in my sig.

Yep, why not?
It's a good option as well.
