Technicare also recommend that you turn your monitor up to 100% in their colour management section! ......... I don't think so. I'll ask them for a profile and check it.

EDIT: One of the widest gamut papers that they offer would be Kodak Supra Endura (Glossy) and they probably use Durst Lambda print processing.

Below is a plot of the paper profile vs sRGB & aRGB. Both of the colour spaces exceed the paper profile in areas, and the paper/printer combination exceed the colour space in other areas.

The paper/printer combination intersects 55% of aRGB and 71% of sRGB.

This is very common. Some of the very latest 12 colour inkjets would have a slightly larger gamut on this paper but not by much.

The first is sRGB in the Red wire cage, the second is aRGB with the Red wire cage. The Kodak paper is the solid colour plot.

The plots are rotated to show the worst case (mostly some blues, greens & yellows) but these extreme edges of the colour gamut rarely exist in nature.

So, my answer to the origional OP would be to stick to sRGB as it is the most universal and as a general rule, would encompass most colours you would encounter.

Hi Tim, indeed it was YOU who is one of only two POTN respondents in the world who could provide the name of a commercial photo print maker who accepted aRGB and printed it without any conversion to sRGB! Alas, your recent response has not increased the number to '3' commercial printers.

Why does a phone company have to do with color space? That's like asking your dentist for advice on fixing your car...

I think he meant he got that information from CALLING Technicare on the phone. Telephone communications with the printing lab.

For London Drugs . . . sRGB. Black's wanted sRGB. I assume it is the same for Walmart and Costco. Even Vistek wanted sRGB the last time I spoke to them about what colour space they wanted (that was in 2013 . . . might be worth discussing with them again). I actually don't know of any printers that specifically want Adobe RGB. The ones I've spoken to either say sRGB or that they don't know (which is kind of scary).

For the web . . . sRGB. Most monitors and devices don't support the entire sRGB colour space, and I think Adobe RGB compliance is a long way off. sRGB is the lowest common denominator at present.

In a few years things might change and the Adobe RGB colour space might be utilized fully by consumer products. You can tweak and re-export anything that you want to print or display as Adobe RGB then.

Exactly what I needed to know, thankyou!

Save for what???
I always save ProPhoto on my HD as there is occasion that things may need to be changed, also, I do not flatten my images.
Going into sRGB is reserved when they are to be printed...that shift to sRGB often requires some minor image tweaking.

Generally flickr or printing. When I export from lightroom it does a good job of keeping the colours, but photoshop not so much. I am worried that if I save in too expansive a colourspace, it won't display correctly on other devices or be resampled by flickr/facebook what have you.

If you are doing your own printing on a photo printer (e.g., low end would be Canon Pro-100) then RAW, ProPhotoRGB and the final print is made from 16bitTIFF_ProPhotoRGB (assuming color). There was a lively discussion in DPReview on the topic that ended with a video and test prints: http://www.dpreview.co​m/forums/thread/396433​7 (external link).

I didn't make it through five. :lol:

But, in all fairness, they were discussing a different situation. For those who do their own printing in a closed and calibrated colour control system that they themselves maintain, things can get more complicated.

For those of us who have our printing done by outside sources, or who are processing images for web or mobile viewing, we typically have the luxury of taking a very simple and pragmatic approach.

It is very nice to see that throughout this thread common sense has prevailed.
