Scanning in RGB

Hi, this is my first new topic post. Please let me know if there is a more appropriate forum to post this. Here's my question:
I have an Epson Perfection 2400 scanner which I have used for years with my Windows 7 computer. I just got a new computer with Windows 10 and downloaded the driver for the scanner. On the old computer I'm pretty sure that the scanner defaulted to the RGB color space because it was in RGB when I opened the scanned .tif file in Photoshop Elements. Now with the new computer and driver, the scanner defaults to sRGB, and I don't see any options in the driver window to set RGB. Has anyone run across this?
Thanks

I would use the sRGB setting and not worry.
(My camera is set to use the sRGB color space.)

sRBG was fashioned to handle the phosphors in televisions. It is a much smaller color space than Adobe 1998 RGB. Check the graphic attached.

Careful using Adobe RGB, it's not supported everywhere.
(sRGB works best for web posting and many print houses.)

Thanks John F. I use Adobe RGB in my printing workflow, so I'd like to include my scanner. If my scanned image is sRGB, can I just convert it in Photoshop before editing and printing? Is that the same as starting with an Adobe RGB scanned file?

Dunno about converting it, but, look again at the graphic from John F - you cannot get the additional colors/hues of Adobe RGB, 'cuz they're not in the sRGB at all! The missing colors are gone forever.

Of course you can convert your Adobe RGB image to sRGB and that is exactly what I would do if I were in your case. Look for Convert to Profile, usually in Edit.

But you cannot (accurately) convert sRGB to Adobe RGB as the sRGB does not have as many colors.
For viewing on-screen and on the web, sRGB is what monitors use.
Most monitors cannot even display all of sRGB, much less Adobe RGB. (that new 32" Apple monitor with the $1,000 stand could do it!)

But if you have a professional ink-jet or dye-sublimation printer that has MORE than 4 color inks (like a darkAND a light magenta etc.) , Adobe RGB will allow you to print colors that your monitor cannot display.

Many photo-printing services only accept sRGB (thus offering somewhat inferior color).

Personally, I would shoot or scan in Adobe RGB and keep the original for best color range, and convert a copy to sRGB if I need to post on the web or send to a consumer photo-printer.
