Following the other topic...
What I am trying to do is to use the ICC Profile to change the appeareance of my images.
To do so I've created a base ICC profile in combination with my camera (for certain lights condition) and I've started to play around with it in Profile Editor to tweak the colors of the images themselves.
I know it's not the classical way of using the ICC profiles but I've seen that the results I obtain are of a better quality rather than making the color corrections with the classical panels in photoshop.
I also like the fact that I can apply the profiles to the images while I am shooting and see directly the results (and if to apply some modifications).
I know I should better use some "abstract ICC Profile" but I am going crazy as I don't understand how to create them and how to use them...
So I am directly editing the original device camera profile but I am going crazy to convert the images back a RGB space (like Adobe 1998 or ProPhoto) as the colors change.
What I have been doing so far is this:
- Rendering the image from RAW to TIFF with all the parameters set to 0.
- Assing the modified ICC Profile.
- Converting the image to LAB color space with Absolute Colometric rendering mode.
- Converting the image to Adobe RGB with Relative Colometric rendering mode.
This method works perfectly for some of the profiles I've generated (it removes posterization if there is some) but terribly for other (as it changes the colors, especially in the shadows).
If anybody has any suggestion I would really appreciate because this problem is driving me crazy.
