Hi. Thanks for the answer.
I want to try that. I don't actually get it... can you be a little more specific with the steps? 
- Does this procedure will allow me to change a whole photo from one "general color look", to another?
- Each pixel is a different color in the color table? So I should have 16x16 = 256 colors?
- Do I save it directly from photoshop as a Raw file? What extension?
- For converting, I should use "convert to profile" in photoshop?
- To change to the target color table? Assing profile?
- If, for example, I want to make the variation from one digital camera to a vintage camera... I create a 16x16 color table, I take a photo of it with the digital camera, and then with the vintage camera. With the first file I create the first act, and with the second, the second act. Then I convert any photo from the digital camera to the first act, and then I assign it to the second act? Is this correct?
Thank you for your answer! This is getting interesting...
