Lightroom GPU

When editing, the washouts of Black and white come in as either blue or red washout.

This warns of burn out and black out I guess, but stops me seeing the photo as I wish.

Googling it suggests turning off GPU. WTF is that? Apparently GPU is in preferences, but for the life of me I can't seen anything resembling GPU.............

I am assuming preferences in in the EDIT submenu...............

Any ideas...............TIA...

Re: Lightroom GPU

Graphics processor.

Edit->Preferences, then "Performance":




BUT - you can turn off the "washouts" by pressing the J key.

Re: Lightroom GPU

Thanks Paul.

It was turned off anyway, so original problem this there.

Turning it on slowed the process considerably.............

Never mind...

I guess its an outside shot but you cued try this. *At the very bottom of the adjustment panel on the*right side, you'll find a Camera Calibration tab. Make sure that Process 2012 (and not 2010) is selected. Regards Andrew

Forgive me if I not understanding correctly, mine does the same for over/under exposed highlights and shadows, to view/hide pure white or pure black, just single click on the top left of the histogram to show/hide shadows (blue) or top right to show/hide highlights.
Having read your post several times I'm confused now.

You're not alone. 'Washout' - I've never heard of that before, but highlight burn and shadow underexposure operate as you described.

Re: Lightroom GPU

As Timboo says the red/blue overlay are just a feature showing over/under exposed areas and can be turned on or off by clicking the triangles at the top left and right of the Histogram in the Develop window.

Re: Lightroom GPU

Thanks all. yes the little triangles on the histogramme switch the Blues and reds off, as does the "J" key.....

Can get back to seeing what the photo looks like now. But its a good tool I guess to see those over/under exposed bits................

Re: Lightroom GPU

And if you normally have them switched off but want to do a quick check, just hover the mouse pointer over the little triangles.

Re: Lightroom GPU

What you can also do is to press the alt key down and adjust the black or white sliders. That way the whole screen goes either black or white and you can see easily which bits and how much of the scene is burnt out white or black. This takes away the distraction of the image and I often use it that way as well. Gosh just realised I'd posted a LR tip bit of a first for me mind you I did get it off a mate

What hardware are you running? I think the hardware acceleration option only helps if you have a really fast video card.

I'm actually not quite sure what your original question was trying to ask! Can you rephrase?

Re: Lightroom GPU

Ian,

Original Q was abut the blue and red colours on the photo where the whites were blown, and the blacks blacked out.

I used the word Wash out, I meant that a blue washout was a total colour with no detail, to show you that the shadows were too dense...

Not sure that explains it any better, just toggle the "J" key and you will see what KI mean on a dark or bright photo.........

Anyway all sorted now..

Re: Lightroom GPU

Righto - what was slowed down by enabling the GPU setting?

Mine is enabled but I have a fairly high end nVidia card here.

Its a very strange option. Since I updated Lightroom to classic CC, I'm now able to use GPU acceleration and edit a lot more smoothly.
On previous updates I couldn't use the GPU option without my PC grinding to a halt.
Maybe its because CC was supposed to be a bit more stripped back so less labour intensive on my PC. Who knows.
One thing I do know is that I'm not going to update again.

Ian,

Dell laptop with an Inter (r) Intel Graphics 4000. I have just switched the GPU, and all seems to well. Not slow at all. Not sure why it was jerky before.........

Thanks for help............
