Question

Assign- Convert - Proof Colors

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?

    What's the deal with these Adobe forums anyway? A guy asks a question, and rather than answering the question, you arrogant fools always ridicule, argue, and play king of the hill. Isn't the entire point of a forum to answer questions and discuss relative solutions. Trying to prove you know more than the next guy only makes you look insecure.

    I recognize a few names in here who have done the same thing to me when I asked a straight forward question before. There are some users who are immensely helpful though. Thank you to you all who like to help others, rather than prove your superior knowledge.

    Ok, if you want to call it inappropriate that is fine with me. I just hope you have now made up your mind what you want to call it.

    It's an echo chamber, my friend. Margulis invented the term, and others started repeating it, because, sadly, he is still influential. So your "proper search" finds instances of it most of which are related to...Margulis! Is that proving anything other than his influence?

    Still, why is the profile "false"? As far as I'm concerned, a profile is either appropriate or inappropriate, based on the originator's expressed intention (if the profile is embedded) or the recipient's interpretation of the image (if no profile is embedded). There is nothing that makes any one profile inherently "true", therefore nothing that makes it inherently "false" either. It's all up to either honoring an existing workflow or expressing a preference.

    As for your gratuitous insult, that says more about you than me, I'm afraid.

    If you know how to do a proper search you might actually learn something.

    http://www.google.com/search?hl=en&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&hs=8fT&q=%22false+profile%22+color+management&btnG=Search

    I also did a search for dumb ass, and the name Marco Ugolini came up. Sound familiar.

    Marco,

    Call it whatever you want. A lot of people who use false profiles refer to them as such. If you're not comfortable with that term, that's fine too, but at this point the horse is quite beaten.

    Seems to me the poster of #56 came up with that doesn't fit term. Maybe you would be better arguing with him about that.

    O intelligent one, nice dodge there, but you still haven't answered my question: what is "false" about the profile assigned to the image?

    Ok, we will assign a profile that doesn't fit to convert to a final profile to achieve what we want for the final result.

    If you still don't understand that, you never will.
