Issues with ICC profile & graphic processor

[Gianni_Baccega]

Hi,

I've got a problem with Lightroom 2015.8 on Mac OS 10.11.6 (El Capitan).

I usually work with the graphic processor turned OFF because it causes a strange behaviour when I turn on

the highlight clipping, the edges between clipped part of the image and not clipped are redenre wrongly, as you can see

in the following screenshot

CORRECT RENDER

WRONG RENDER

I could easily work with the graphic processor turned off (even though this seems a strange behaviour)

but If I leave graphic processor off there's another problem with the ICC profile.

I've created a print profile but when I turn it on with graphic processor turned off, the white clipped part

of the image turns gray. Tried different profiles (ICC version2 and 4 and matrix vs table) but didn't solved the issue

(table ICC profile v4 solved the problem but I'm not happy with the result).

Here's the screenshots

PRINT PROFILE (WRONG RENDER)

Tried with Mac Pro (AMD graphic card) and iMac (Nvidia graphic card) but both get same results.

Any way to solve this?

Hi Gianni,

Did you try updating Lightroom to version 2015.9?

The Creative Cloud app doesn't show me the update, do I need to download it from Adobe website?

I don't think this has anything to do with the graphics processor. It looks to me like the highlight clipping indicator is enabled and the red is showing that your highlights are being clipped. Try adjusting exposure or highlights, or disable the clipping indicator by clicking the little box in the upper right-hand corner of the histogram. I really suspect that if you turn off that indicator that red will go away.

Tried the 2015.9 update but didn't solved the issue.

@JimHess the problem is not the red indicator, I know that turning it off the red goes away.

The problem is that the clipping indicator shows different things (look at the edges) when turned on or off, the right one is with graphic processor turned off. The following problem is that with graphic processor turned off Lightroom shows me the white areas as gray when using a custom ICC profile and this doesn't happen with graphic processor turned on, but that brings us to the first problem.

PS: I've tried to recreate the profile with i1profiler + i1display, keeping the same settings as the fault one but only changing from table to matrix and with this one the "gray" problem is solved, but I'm not very happy with the results of the calibration (the table profile is much better).

Every solution I try has some tradeoff that bothers me.

What happens if you sample the gray area with the white balance tool?

You can try signing out from the creative cloud application manager and then sign back in. If that doesn't show the update then you can download it from the following website:

Download Photoshop Lightroom

The updates are available under the Adobe Photoshop Lightroom 6 link on thatThe screen.

I was able to update but didn't solved the issue.
