I use Lightroom 3 for most raw photo image processing, finishing in Photoshop.  My current camera allows either sRGB ( in various Nikon recipes) and AdobeRGB.  Lightroom allows outputting in the larger gamut ProPhoto color space also.  With raw files, that is possible since a color space from camera is not limiting the raw data file.

The question:  Do any of you use the larger color spaces such as AdobeRGB or ProPhotoRGB?  If so, please tell me if the results IN PRINT are worth it.  A monitor will not show the larger gamuts but fine prints can reveal much of the larger color space I am told. I process to display here on 'rosity but certainly take the really good ones to edit for print with the most care my distracted mind can muster.

Is the use of AdobeRGB or the even larger ProPhotoRGB worth it  in printed images? Is there a preference?

Any comments will be very much appreciated. Site mail if desired. 

Thanks. Blessings for Wonderful Holidays.         TomDart.

PS. Have been using the trial CS5.  The upgrade from my CS2 is not badly priced and I will be moving to CS5 befrore long.  Believe it or not, this new version seems to run with less effort  than CS2. Who knows why but that is a good thing.

** You will not see any difference on a monitor or in a print, which have a smaller gamut than Prophoto RGB. Few monitors have a color depth greater than 8-bit, and most are 6-bit with dithering. Printers seem to fall between sRGB and Adobe RGB in gamut, but comparisons are complicated between RGB monitors and CMYK ink sets.**

Danny, it is good to hear from a friend here.  Thanks for helping me better understand.

When it comes to CMYK, I give that task to the ones doing the printing.

I saw the ability to  process out from Lightroom in Prophoto and wondered.  I do hear it has some advantage besides the color gamut but do not recall just what that was.  I need to go back and see just what Kodak says.  I could bite off more problems with the newer gamut and will likely avoid it until I have a properly color managed computer better able to handle 16 bit files.

I don't know enough about it to ask more.  Thanks.

 I can see a real difference in (most) prints from my 6 color Epson when using AdobeRGB compared to sRGB.

While you can’t see a difference on a typical monitor, the color space of sRGB is narrower than what most home and commercial printers are capable of.

The AdobeRGB gamut is a closer match for them, while you are being short-changed with sRGB.

The ProPhotoRGB, space is huge!

Much larger than what any monitor can show, and printer can produce.

I have used it, but the printed results were too unpredictable… (Always felt like I was flying blind).
