But note that it is not included in the Photoshop installallation, and has to be downloaded from ECI.Īdobe RGB is a particularly good match for ISO Coated, it can usually be converted with little clipping (and sometimes none). In the EU zone, ISO Coated v2 300% (eci) is currently more or less the industry standard for books, magazines and so on, and the safest choice. Which one specifically depends on a lot of things, not the least where in the world you are. If you have direct instructions from the printer as to which CMYK profile to use it's a different matter (but the conversion itself should always be done as the very last step). Repurposing for different press conditions should be done from the original RGB file to avoid troublesome CMYK to CMYK conversions. With regards to CYMK, I haven't needed to send anything to a professional print shop, so I'm in the dark with what color profile for CYMK to use, although soon I may have to.ĬMYK is generally best left to prepress, so it's always recommended that photographers submit RGB files for offset print. Now I distribute my photos in AdobeRGB (not in CMYK because the advertising agency places some text over the images and then converts the composition to CMYK). Quite obviously the editor had simply assigned AdobeRGB space to the images without converting the number values. On a couple of occasions I’ve sent my photos to an outside advertising agency, in ProPhoto space, and the results were horrible (severely lacking in contrast and saturation). In a small gamut the multiplication process may result in clipping. For instance, if you want to increase contrast in almost-blown areas, such as snow or swan feathers, you can multiply the image with a copy of itself, and then locally brighten areas which are too dark. A benefit of using ProPhotoRGB is that you use global adjustments that take RGB intensity values beyond the AdobeRGB and then add local adjustments that bring the intensity values back to AdobeRGB gamut, without losing information in the process. I believe that ProPhotoRGB is best used as working color space, and AdobeRGB is wide enough for finished images. ![]() The areas where PP RGB will contain more colors than Adobe RGB are in strong reds, oranges, greens & blues…if you images don't obtain those colors, you may well not see any actually differences in normal output…but test it out and get back to us.įeel free to correct me if I’m mistaken. I encourage you to test ProPhoto RGB with some caveats…first off, no display can actually show the full gamut of PP RGB…the wide gamut displays can only approach about 98% of Adobe RGB so when working, you need need to be sensitive to the fact that some colors in PP RGB will not be visible on your display…and that leads to the second caveat, that you are working on a calibrated and profiled display…are you? Both sRGB and Adobe RGB will clip colors your camera can capture and once clipped, they can not be added back. The advantages of ProPhoto RGB is that it's the only color space that can contain all the colors your image can capture in raw and all the colors that todays wide gamut printers can print (ignoring CMYK for the moment). Glad that you know the differences in 8 vs 16-bit because if you are going to use ProPhoto RGB, you'll need to work on 16-bit images to avoid potential banding. The only thing Is I never worked with ProPhoto RGB, But As station_two wrote: ProPhoto RGB is the widest space, and I am going to give it a try. If I want to save my Images for the Web, I save my Images by saving Image-Save for web, and I have the Convert to sRGB box Checked. Īlso, Inside Photoshop Color Setting Color Management Policies, I set It for Preserve Embedded Profiles. If I want to send my Images for a Professional Print shop, I convert my images to CMYK and most of the time I use U.S.Web Coated (SWOP)v2, Unless the Professional Print shop CMYK Is different. If I want to print any Images with my printer I save my Image as a Tiff Format with the Adobe RGB Color space. Inside the Photoshop my working space for the RGB,Is also Adobe RGB 1998 I always open my Images Inside the Camera Raw, and my Color Space Inside the camera raw is also Adobe RGB 1998,and my Depth Is 16 bit. There is no ProPhoto RBG Color Space In my Canon 5d. When I shoot with my Canon 5D, I always shoot Raw, and The color space for my canon 5D is Adobe RGB. I know Adobe RGB has a wider range of colors, than sRGB, but most Browsers work better with sRGB. ![]() ![]() So there is more Information to work with. The 16 bit gives us much more values for each channel Instead of only 256. ![]() I believe I know the different between 8 bit and 16 bit, 8 bit uses numbers from 0-255 Red Green Blue for color and channel, In other words 255 is the maximum amount of that color.
