P: Color lookup turns black and no start screen

Do I understand you're stating that you can't use .look files on your Mac? You're using the .look files that come with Photoshop? Or trying to open one from Speed Grade? As I recall, that's the app that creates .look files. As it happens, I have 2015 still installed, and all of the LUT files that ship, including .look, work just fine on my MBP running El Capitan. They also work in Yosemite, and in CC 2017. The LUT files I've created work in PS just fine, too.

My video card is an Nvidia GT 750M, if that makes any difference to the display.

Hi Jeffrey,

Just confirming, after another Windows update last evening I am still not able to use certain LUTs. I'm not going to uninstall this update especially as Windows announced another major update in the coming weeks - Windows 10 Create - which is supposed to give us enhanced 'graphic abilities'.

Hi Denny, I am not able to reproduce this issue. I can open an 8-bit or 16-bit RGB image, create a Color Lookup adjustment, and select "2Strip.look"

The image doesn't turn black.

Today my operating system installed the security update KB890830. Then Color Lookup did not work again.

Just uninstalled this. Then it works again. Windows want to install the update KB4013429 after uninstalling KB890830, but I blocked it.

Well done Adobe! We still have a vulnerable operating system since December 2016 and you still did not fix this little issue.

Hi David, I'm not able to reproduce this issue in CC 2017.0.1. Are you still having this issue? If so, we'll need to dig in more to find out if there's something special different about your set-up/steps.

The application of a Color Lookup adjustment layer selecting a profile with .look extension results in a completely black image. 

The application of Color Lookup adjustment layers selecting .3dl and .cube profiles works.

System datas:
OS X El Capitan 10.11.5 (15F34) - Macbook Pro Retina 15"
Photoshop CC 2015.1.2

Problem :

Open a file

Apply a color look up adjustment layer

Pick "2Strip.look"

Result - black screen



Expected result – application of LUT as in CC2015.5 which works correctly

Note the same issue applies in most, but not
all,  *.look tables. Copying the table
from CC2015 does not resolve the issue

When I select a color lookup, I get a black Image.

Photoshop CC 2015.1

Thanks for the info, Carlos 🙂 I will wait for the next Photoshop update and hope Adobe keep their promise.
If not, then I will use the compatibility mode, because I don't want to block the further Windows 10 updates. You know, it's not really safe 😉
