I have a Nikon 750 and shot in RAW. I have been using sRBG. I shot a lot of land scape but a little bit of everything. I read this article recently that Adobe RGB color gamut encompasses more blue/green hues than sRBG, making Adobe RGB the preferred choice for landscape images or photographs such as cool-colored seascape. So, when should I use sRBG and is sRBG better for such things as portraits, architecture and street photograph? Or should I just leave in in Adobe RBG.
My question is when should you use Adobe RBG and when should you use sRBG?

I suppose it depends on your editor???
I decided on sRBG because of compatibility.

Did you think to try the search function, above, for RGB?

The discussion at this link should help your understanding. http://www.uglyhedgehog.com/t-364870-1.html

There are several links in the various responses. You should have a look all the linked information as well. By the questions and the proposed approached you've described, your understanding at this point is deficient.

The fact you shoot in RAW is 99% of all that is needed. Followed by the edit software (and the color space settings) you use and finally how the images will be used.

If you shoot raw, there is no need to specify a color space in camera, so to answer part of your question, it doesn't matter in the camera settings. However, when you open the image in Lightroom, and possibly other raw converters, you are in a color space called Melissa RGB, which is the same wide gamut as ProPhoto, but instead of a gamma of 1.8 it has a gamma of 1. You cannot change the color space in Lr, it is what it is. Adobe has determined that this will produce the best image quality.

It makes sense to continue to work in ProPhoto, to preserve every last bit of your capture's detail, color and tonality. Once you have finished in your raw converter, you would export the file as a 16 bit ProPhoto file, usually a TIFF or PSD, to your pixel level editor (Photoshop, Corel, etc) again, to preserve your detail, color and tones.

Once you have finalized the image in your pixel-level editor, you can save your image as an sRGB jpeg. Even though the jpeg is only an 8 bit file, and really does not show an Adobe RGB color space as well as a 16 bit file, using a 16 bit, wide gamut workflow will yield a better looking jpeg than if you converted to jpeg and edited the jpeg before finalizing. The latter will almost always result in loss of detail, color and tonality, and subtle tone and color transitions that appeared smooth and gradual can start to appear banded or posterized.

When saving the image to jpeg, you will need to understand how this image will be used. If it is going to be printed commercially, sRGB is most common, though some high-end print labs do offer 16 bit AdobeRGB printing capability. Don't assume that if they accept Adobe RGB 16 bit files that they will process them as such. Many labs will accept them but will convert them to 8 bit sRGB in their workflow, negating any benefit of wider gamut and deeper bit depth.

Regardless of what many many other people have written about color space and bit depth, none have a greater knowledge and understanding of digital color space than Jeff Schewe. His mastery of the subject is far better than anything you will find in SLR Lounge, fstoppers, Reddit, KenRockwell, Tony Northrup or any of the other popular sites where people can be easily mislead with wrong or incomplete information. When you Google his name you will likely find this quote, "Jeff Schewe is a world renowned Photoshop expert, professional commercial photographer, and digital imaging artist. Jeff is a member of the NAPP Photoshop Hall of Fame. An award winning advertising photographer by trade, he is known as a digital pioneer and has been a long term alpha/beta tester for Photoshop, Camera Raw and Lightroom."

The contingent of Adobe alpha testers is a very exclusive group, and they are all uber-knowledgeable.

And thank you for the tip on Melissa RGB.

Is there an opportunity here????

Always!

Thanks for a concise, well presented explanation on this subject!!

sRGB unless you go to a professional printing company uses RGB, and the colors could be better.

My cameras are set to Adobe RGB and a Process in LR/PS in ProPhoto

Gene, excellent contribution. Jeff was pretty instrumental in the development of ACR. As far as Photoshop goes he walks on water while many others are trying to dog paddle.

I have my camera set to adobe and shoot in raw . I took photos of things that had a main different color then the other photos in srgb and in adobe . Opened the photos in PS which I have tried in srgb and adobe color setting .The colors matched adobe setting from camera to adobe setting in PS and the colors were off in srgb from camera to srgb in PS compared to what the colors looked like I took photos of in real life . I have a 100% srgb - 99% adobe color accurate monitor which is now set to adobe , but has a dongle that will allow me to switch monitor to srgb with just a click of a button and back to adobe . I do my own printing and adobe is much closer of a match . Printer is set to color management Adobe too. You can do the same test I ran with your camera and you decide if the photos match what you photographed better in srgb or adobe . It's just that simple ...Tommy

First off, there is the question of how you should set your camera up if you shoot jpg or raw. If you shoot jpg, this choice is very important because the color space you choose it "baked" into the image by the camera. If you shoot raw, it doesn't matter. So if you shoot jpg, always shoot in the color space that is that largest. You can always reduce the color space, but you can not increase it.

Secondly, the color space you edit in, and the color space you choose to use for printing, and the color space you use to post or email images are all different.
a. Always use sRGB to email or post images to the web. Any other color space and your colors will not be right to those that view your images
b. Always use sRGB to take or upload to a place like Costco if you want them to print your image. The only exception would be to use a color space if you are sending your images to a pro print shop for publication. Then you'd use a larger color space but you'd have to ask the lab what color space they need.
c. Edit using the largest color space and save your final image using the largest color space. Convert the color space for any of the reasons stated above. Use ICC profiles when you get to a more advanced level of experience and understand them and use the highest color space your printer manufacturer recommends. If you use different paper than what your printer manufacturer recommends, use ICC profiles to adjust the color in proofing but do not embed the profile in your image.
