Title: Out of Gamut representation Post by: alandb on December 03, 2023, 08:03:07 PM After working on a photo in Lightroom, then Photoshop, it came back to Lightroom to then print from QImage. My normal process. After printing, I noticed that the bright orange in the middle of the flower was slightly washed out. After reviewing several things, 1) I noticed that the QImage image of the photo was a closer representation of the actual print than the Lightroom image. Yes, my monitor was calibrated the day before. 2) When I went back to Lightroom to review the softproofing of the photo (something I don't always do but will now), it showed that the bright orange part of the flower was, actually, out of gamut. It would never have occured to me that that kind of color would be out of gamut. 3) My basic question for QImage is, does it really have the capability of rendering the out of gamut parts of the photo correctly? If it does, I am amazed. I will go back and review what out of gamut really means.
Title: Re: Out of Gamut representation Post by: admin on December 03, 2023, 09:23:08 PM Qimage offers the same tools as other software for handling out of gamut colors. The rendering intent handles that: typically relative colorimetric vs perceptual intent. The only difference is that Qimage does offer an "automatic" rendering intent that can automatically select between RC and P based on what parts of the photo are out of gamut. But you may not be using "Auto" rendering intent.
There are other things that can make Qimage render prints better such as Qimage's rendering of raw files... but I don't know if you are using raw photos.

Since I went from Lightroom to Photoshop, the image is a TIF file. I don't know if that makes a difference. I did use a specific paper profile (Epson Exhibition Fiber, my typical test photo paper because I got a huge amount for free) in Lightroom and then, without actually printing, tried a few other profiles of paper that I use that showed less out of gamut areas (Canson Rag Photo). This is a new area of printing for me.
