Why not use Adobe RGB for my wor

Why not use Adobe RGB for my working space being as it’s the graphical standard?

Go right ahead. If your output is to a graphic client it’s a terrific idea. Capturing images in the sRGB color space, then setting Adobe RGB as your working space in Photoshop is a perfect way to
properly move small format capture files into Adobe RGB. In fact, it’s a better way than shooting in Adobe RGB. Photoshop will place your files data into the Adobe RGB space better than simply “tagging” it in Adobe RGB in your camera. This is how we do it here in Crockett Studios when we need to work in the Adobe RGB space using small format digital cameras.
Please note that with your files coming out of the camera in the sRGB space, and Photoshop set to a working space of Adobe RGB, you’ll get a “profile mismatch” warning with every file you open a file.

Simply choose the “convert into working space” option and let ‘er rip.
But wait... if you shoot in sRGB and you plan to print it on an in-house printer, or you will be sending it to a portrait lab for printing, there’s no need to ever convert the file into the Adobe RGB space. In fact, it’s a waste of valuable time. If you shoot in sRGB, open in Photoshop in sRGB (sRGB is the Photoshop RGB working space) then print in a space that’s smaller than sRGB, why force the file into the larger Adobe RGB space in the process?

Don’t forget these two facts:

every time you convert your data - you lose some data and distort more, and

portrait labs want files in sRGB, not Adobe RGB.

The choice is yours and only you can decide the right workflow:

If you scan transparencies on a high end scanner, then scan into a custom input color space created by your scanner itself to hold the data properly, then open it in Photoshop by “honoring” it’s embedded profile.

That’s proper digital workflow.
And if you want to move portrait or wedding type files in and out of your studio to get consistently great looking prints, set your digital capture camera to work in the sRGB space and set your Photoshop working space to your cameras sRGB space.

That’s proper digital workflow.
There’s lots of photographers making lots of great looking prints (and money!) right now with this simple sRGB workflow.

That’s proper digital workflow.
Skeptical? GOOD! I was too. Try it and see?

But if you want the best possible image you can squeeze out of your digital camera, especially if you’re shooting landscape, fine art, or commercial work, then shoot RAW, convert to 16 bit AdobeRGB, then convert to your specific printers 8 bit output space (we recommend getting a custom profile for your printer) in Photoshop and send it to your printer.

That’s proper digital workflow.
But if you're shooting senior portraits, or weddings, or corporate headshots why spend hours and hours processing all these 16 bit RAW files? Why not shoot film instead - it's faster.
Set up a portrait and shoot it RAW, and shoot it again in sRGB. Process to a print from each file and compare. You'll see that the simple sRGB workflow is faster, easier and creates a print than both you and your customers will be proud of.
Just remember that no data outside of the sRGB space can be printed by the big portrait labs (without a custom printing fee) so if you shoot in Adobe RGB be sure to convert it to sRGB before submission.

The Bottom line
So if your client wants images in Adobe RGB, give them Adobe RGB. And if the lab you work with wants images in sRGB, give them sRGB. What’s there to argue about?
