Hello. I like the idea of RAW scanning but i still can't understand how the ColorPerfect works and how to organize correct workflow without color data loss. My aim is to output more-less correct images with ProPhto RGB color space for further adjusting in Camera RAW or Lightroom Let's suppose that i have scanned color negative in Vuescan to image with linear gamma and without color profile in it (as described in ColorPerfect FAQ). Before process it in ColorPerfect i need to open image in photoshop. When i open image in photoshop i see a dialog box which purpose me to leave image without profile or assign profile. And here begins mystery. As i know it is not correct just assign profile to untagged image, but in ColorPerfect plugin FAQ it is told that i just need to assign profile to image (just assign, not convert) before or after processing. OK i left image untagged and assign ProPhto RGB to it after processing and have madness saturated colors as i expected of just assigning profile. Correct me if i wrong but image needs some starting coordinates for RGB values, sone starting scanner color space to begin work with or convert color coordinates to another space, and it is wrong to put untagged image in photoshop or ColorPerfect which have no idea how to understand those image. So my general question is to those who uses ColorPerfect - how should i open image in photoshop before process it in, and how should all workflow looks like to have image in ProPhto RGB color space?
