Lightroom 5: ICC Table Profiles clipped shadows under OSX

Hi, I've just found a really bad issue occurring in Lr 5 (but also in all other Lightroom versions) under Mac OSX 10.9 with a calibrated monitor: dark shadows (from a value of 20 to 0) are all clipped (pure black with no detail and no textures) while the histogram remains ok, indicating NO clipped shadows at all. This issue afflics also ACR.

Photoshop for now is the only software under MAC that reproduces dark shadows correctly: Library Module shows a bit darker and shifted shadows than Ps but acceptable, Develop Module is really bad showing brutally clipped shadows (but you work in the Develop Module right?!).

The same problem occurred also in OSX 10.8 but it was related only to LUT profiles, creating a Matrix based profile problems were solved.

Now the issue occurs with both Matrix and LUT profiles, v2 and v4. There's no apparent way to make Lr working right.

Under Windows no problems at all: Bridge, Photoshop, ACR, Lr (Library Module and Develop Module) show the same correct NOT clipped shadows.

I tested 8 different Mac running 10.9 with different GPU, different monitors, different profiling Softwares (Color Eyes Display Pro, Eizo Color Navigator, BasICC Color, i1 Profiler). Same results.
I tried to change the gamma value (2.2, sRGB, L*) problems remain. I tried to change ICC version (v2, v4) problems reamain. I tried to change profile type (LUT, MATRIX) problems remain.

How can a photographer work professionally on RAW images if shadows are bad reproduced?

Why Photoshop can reproduce shadows correctly while Lr isn't able to do that?

Why this happens only on a Mac enviroment?

Is Lr based on ColorSync (that can't handle profiles correctly) while Ps isn't (because it can handle and it has no problem)?

Please Adobe, FIX IT for all professional photographers, we can’t use Lr for serious works under Mac.

An update: Eric has identified the source of the clipping issue and we are currently testing a solution. More info as it becomes available. Thanks for your patience.

Should be fixed in Lightroom 5.7: http://blogs.adobe.com/lightroomjourn...

Not fixed for me: fixed only for matrix based profiles, table gamma profiles (used by pro monitors like Eizo Color Edge and NEC Spectraview) are still showing clipped shadows.

macOS Sierra, Lightroom 6.7 and bug exist in Library module and Develop (if Graphics Processor turned OFF)

Does this only happen in 10.9, or does it happen in previous OS versions as well?

It sounds a lot like a regression of an old MacOS ColorSync bug...

Hi Chris, as I wrote, Lr 4 under Mac OSX 10.8 suffered the same problem but with LUT profiles only. No problems with Matrix profiles. Now problems with both and no way to correct them.

Adobe should reprogram Lr 5 to work properly with ICC profiles under Mavericks, until they solve the problem no professional work should be done using Lightroom on new or updated Macs.

Chris, how can we inform adobe engineers about this problem?

And what can I say to my Lightroom classes? "Guys, shadows are all wrong if you use Mavericks" ?! Pro photographers don't care if it's Apple or Adobe related issue, it's Lightroom that doesn't work properly....

Here is a link to the original photo I use to post the 100% crop example.

I can send tons of images where the issue exhibits. But every image with an area of shadows with a value between 20 and 0 should be fine.

I can't reproduce the problem here, even with your file. I'm running LR 5.3, looking at it in Develop at 1:1 view. And Photoshop CC, again at 100% view. Both on the same EIZO CG243W calibrated using BasICColor software, Matrix profile, v2, L* on Mac 10.9.1. They're identical. You've ruled out quite a number of issues - have you ruled out your calibration hardware?

This reply was created from a merged topic originally titled
dark previews in Lightroom 5.3.


previews in LR (both Library and Develop module) are darker and more contrasty vs Photoshop

(Adobe Bridge shows previews exellent)

OSX 10.9.1, PS CC 14.1.4, LR 5.3, Eizo CG 19 calibrated with Color Navigator 5.4.5

It sounds strange. Are you looking at the shadow zone on the right? You must look at the part of image showed in the first example.

I tried calibrating with Spider 4 and i1 Display Pro using i1 Profiler, BasICColor, Coloreyes Display Pro 1.6 and Eizo Color Navigator 6.4.6 (only for my Eizo).

The problem is the same on 8 Macs (mine included). It shows up on the Eizo as on the apple LCD screen and iMac. Every colleague I consulted has the same problem...

Note that the same calibrating hardware and software doesn't cause problems on Windows...it can't be an hardware related issue.

Yep, I'm looking at exactly the same spot as you Max. I went back and checked it against your screenshot.

I'll carry on experimenting with other software to see if I can reproduce it.

Please note also that the difference in shadows between Library Module and Develop Module shows up with the standard OSX included profile (with the Retina LCD screen included profile as well).

I try to create just now an L* profile on my eizo....

Please tell me which graphic card are you using on your mac. If your basic (included in OSX) profile doesn't cause problems, it might be a Graphic Driver issue, beacause mine does.

Oh my...the same I tested, the GPU is the same... Really I don't understand. How can your mac work correcltly when every mac I tested showed up the issue?

Which calibrator? Currently I'm using i1 Display Pro with Eizo Color Navigator 6.4.6 (Mavericks compatible).

There is a fresh update for Color Navigator... let my try. Fingers crossed.
