In Photoshop, I can choose to assign or convert to profile. This seems straight forward, I think.

I was given images in ProPhoto RGB color space (8 bit). Just as a test, I did two things. I created a Proof setup that used Adobe RGB and Peceptual Rendering intent. Then, I also went to Assign Profile. Both cases the image was darker and lacked detail (given the smaller color space)...

My working space for RGB is Adobe RGB with perceptual rendering intent.

Next I turned the proof colors off and I converted the file to Adobe RGB. In this case, the color changed very little (was not dark at all).

I thought I understood that if you assign a profile, the appearance on screen will differ (and the numbers will stay the same), If I convert, the numbers actually change.

question: Why would the image look very dark when I was assigning the profile, but look the same as the original when converting?
