Hi, I'm having a color managment issue with my Canon R5 & RF 24-70 lens. My editor/post processer of 7 years sends me jpegs that look washed out, missing reds, flat, etc. Everything looks good on her end and on my graphic designers end, so I figured it was my screeen (althougth all of us are on calibrated imacs, using the same color profiles, etc and same version of photoshop and bridge).For the first time in 20 years, I've gotten some complaints and comments from clients regarding the color. I recently started printing orders for clients and the prints match what I'm seeing on my screen (washed out colors, little to no reds, flat, etc) . Adobe escalated my case and said a senior tech would call me muliple times and never called. I finally spoke to Canon yesterday and they told me about an issue they are seeing some R5 or RF lens users involving adobe. I'm not techinical, so here's what I heard them say:

"Lens correction data is shifting color profile" and they recommend remoing the lens profle from Photoshop or adjusting defringing.

Any help would be appreciated. Thank you.

It has only happened when I got the R5 and I only shoot with one lens.

The images my editor is sending me look nothing on my screen like they look on hers. We have zoomed. Also, my raw images in Canons software look different than in Camera Raw. My computer they are missing colors, desaturated, no reds in faces...lips blue. This is not my labs issue, I only brought up the prints to say that they indeed are printing exactly as I am seeing on my screen....color is way off, desaturated, no reds, flat, etc. These same images look normal on my editors screen, but once they hit my photoshop, they change.

The bit about the lens profile doesn't make much sense to me. So this only shows up with that one lens and only when the profile is used?

The JPEGs you're received do have an embedded ICC profile (if so what)?

Prints that don't match the display is another store (see below), and yes, this could be a display calibration issue. You do have to have a printer profile that you yourself are using for soft proof AND conversions (not from some outslide lab; that's mostly a bougs workflow in terms of color management).

Why doesn’t my display match my prints?
