Take a tour with us and explore the latest updates on Adobe Support Community. I found a lot of similar threads but not finding what I need to know. I was told to save in Adobe RGB for this particular project. Based on the look of the layout, it clearly makes a difference.
So I don't know how to choose which would be the better option before saving. Assign is what you use if the file doesn't have a profile at all - or if someone assigned the wrong profile previously.
When you convert into a different color space, you're not supposed to see any difference in general appearance.
The numbers are remapped into the new color space, preserving appearance. That's the whole idea of color management.
To better understand the difference, open an image and put the histogram on top. When you convert, the histogram changes, but the image stays the same. If you assign, the histogram is unchanged because there's no remapping. But the image changes because the numbers get a new meaning. The advantage of Adobe RGB is that it's larger, so it can contain more highly saturated colors.
You won't see that directly on screen, because a standard monitor can't reproduce colors beyond sRGB. For that you need an expensive wide gamut monitor. But most printing processes can take advantage of it. Note that Adobe RGB absolutely requires a fully color managed process to be represented correctly. If you're not sure, stick to sRGB. But you will have a little more headroom for future edits.
Adobe RGB is designed for offest press. If your image is taken in sRGB or you are using it in a digtal format then you should keep it there since the colors in CMYK will be far different than what you see on a device ex web.
If your image was taken in Adobe then you should go to CMYK for offset printing CMYK is a very small space so never used for editing since your colors will stay true. If you are shooting in RAW you can go the whatever space is best for you. That's what I prefer though my bought images are sRGB so they stay there. Bottomline is if you are born in a space then stay in the space unless you have to convert even converting it is not exactly the same but a controlled change. If you are going to an offset press then convert to CMYK.
If you are going to a digital press then talk to the printer some still want conversion but most will not but some will request you stay in sRGB but never Adobe RGB Basically color management is about the control of color and not about matching color. I personally mostly use sRGB today. In the picture below you can in the first image that sRGB is smaller than Adobe AdobeRGB was a mistake that shipped before anyone realized and by then it was too late.

Moreover, observe the other four Untagged files are displaying uniquely incorrect. Hence, that was the correct move only for the Adobe RGB file.
In other words, when we configure Photoshop to ignore embedded profiles or we don't give it a profile to use, Photoshop Assigns its Working Space to the source image for all practical purposes. At each Embedded Profile Mismatch warning: "Use the embedded profile instead of the working space ":.
This is sometimes called display with "monitor compensation. Bruce Fraser summed this behavior up in an Adobe forum:.
But it would display incorrectly, and convert to any other space incorrectly, so it's fair to say that while the integrity of the data hasn't been compromised, and you can rescue the file by assigning the correct profile, for all practical purposes, it's hosed. To most effectively observe how profiles work and interact with color management systems using your color-managed Web browser:.
For HELP with monitor calibration, troubleshooting and evaluating monitor profiles. Please read the www. Ballard, www. If the image is un-tagged, we will need to manually Assign the correct profile. To interpret, display and print those numbers properly, the numbers need context — namely, colour space.
All colour spaces are numerically represented by , but red in the ProPhotoRGB space is significantly more vivid than red in the sRGB space, for example. The numbers are the same, but the context is different. Assigning a profile keeps exactly the same numbers, but changes the colour space to which they belong.
