Lightroom: Add 10-bit/channel color display support

Steve is correct.

On Mac: Lightroom has always uses the 16-bit math throughout in the develop module (with ProPhotoRGB as the internal working color space). With the GPU acceleration, it requires at least Lr 6.2 and later.

On Windows: It also uses the same 16-bit ProPhotoRGB math for internal image renders. But the result image data of the final monitor color transform (for display) is currently limited to 8-bit.

"At the moment, all that's missing is the application."

There are thousands of feature requests, so obviously that isn't all.

DSLR's are increasingly pushing the 8 bit envelope. Why would Adobe be content letting their software limit my photography?

Additional question: Does LR use dithering in the develop module? I just loaded the 10 bit test ramp from http://www.imagescience.com.au/kb/que... into Photoshop and LR (8 bit output). In Photoshop, I see the 8-bit-banding, as well as in LR loupe (because previews are 8 bit JPEGs). But in LR develop, there is no visible banding!

This would be actually great, because it is the next best thing to 10 it support.

Edit: Yes, LR develop really seems to use dithering. Here is a small portion of the ramp, with extremly amplified contrast (screenshot from develop module, contrast amplified in PS):

Lightroom: 10 bit monitor support.

I fully understand that you can't give Lightroom too many of the attributes that Photoshop has but a 10 Bit Monitor is just superb [using PSCC] and dare I say the defacto standard for sill digital image editing. It would be really nice to see Lightroom 6 having the same facility. It would also give the two Applications greater synergy when viewing/editing.

I am a very satisfied Lightroom user, but the lack of 30 bit color display capability it's a major shortcoming for a pro grade software.
I hope this feature will be added soon.

we, photographers, need Lightroom to support 10-bit display output for having our advance displays like models from Eizo or NEC producing 10-bit billion color depth

Having just tested 10 bit support in video media with a good - but not ridiculous - rig and seen the difference it makes I am very keen to get 10 bit support on ALL my photo apps.

windows 10 - nvidia 980ti - Dell U2713H. I know this monitor is doing slightly fake 10  bit (as many laptops do fake 8 bit), but the improvement is significant.

My Nikon D3 produces RAWs with 14-bit color depth.  With 8-bit processing in LR, I'm throwing away 6 bits of color depth smoothness and gradation.  As others have pointed out, Photoshop has 10-bit color support, so it's not something that Adobe can't do. And nowadays, both Windows and OS X support 10-bit color.

I'm pretty sure that LR uses a 16-bit internal workspace, while the display is only 8-bits, so the term 8-bit-processing isn't quite right. 

On Windows, it is still 8-bit ProPhotoRGB.

Also remembering that lightroom manages the color profiles on windows (good thing too as windows is - still -the village idiot when it comes to color management), so lightroom *could* do conversion in the best order to drive an 8 bit monitor. Having said that, even with dithering, there is a distinct (visible) quality improvement on going from

• 10 bit source to 8 bit monitor interface
  -to-
  
•  10 bit source to 10 bit monitor interface
  

Even the projector used by my camera club is 10 bit capable and is visibly better with full 10 bit interface.

This seems to apply just as much to nature (trees, leaves, stone etc. - especially when distant) as it does to artificial patterns. I assume that our internal image processing pipeline has evolved to pull as much detail as possible from the photons entering the eyeball.

There is also some interesting stuff happening around video as well as the extended video formats arrive. It is obvious that the eye brain processing that goes on picks up on some remarkably fine detail given the opportunity, The difference between yuyv (4:2:2) video and ful yuv (4:4:4) can be quite dramatic, creating a richer and more immersive image without apparently 'looking' much different. In some ways the result is similar to moving from 8 bit to 10 bit monitor depth.

So if I have LR 6.5.1 on Windows, will I get 10-bit display output if I have the right graphics card?  If yes, can anyone recommend a suitable card.  I don't want to spend "too little" but I don't need the crazy-fast performance that gamers crave.

Thanks.

Application is the only thing missing in true 10-bit workflow now.

Add please 10 and 12 bit  per channel output to driver.
My monitor can handle 12 bit per channel and only Photoshop can use it within 30 bit option.
