Does PhotoLab 3 support 30 bit colour?

Genuine 30-bit monitors are widely available at good prices due to HDR support in many games, YouTube, graphics cards, and more. My Benq 32-inch HDR monitor cost $500 Canadian. DXO needs to support!

Yes. 10bits support please!

One year ago already…10bits support? Please?
Anyone with DXO thinking about this?

Same here, please add this 30bit support feature!!!

One year ago since last post in this thread…only silence on 30bit support so far…
Since last weekend working on iMac next to new Eizo CG2700S. Both able to do 30 bit colour (30-bits color (ARGB2101010)…but then…my all time favourite software doesn’t support it! Bummer! Could its be that difficult to implement? I think it’ s a necessity nowadays. Don’ t want to go to Adobe again. There is other software that does support 30bit, but it would be a real pain in the *** to work all this next to PL.
Again…please add 30 bit colour support! I know you can do it.

Agree 100%…even after 2 years…no sign of it yet…
at this moment I feel restricted.

I’ve only just learnt of this limitation. I’ve voted now.

DxO need to address this failing asap, HDR / aRGB monitors are widely available and the default choice of any serious photographer. Heck, even rank amateur like me has one.

Right stuck (as I said in another thread).I like PL a lot…but this support really should be added…don’ t do anything with HDR, but also there it seems 10/30bit support is very welcome.
Serious software, like DXO PL,
needs serious capabilities.

More and more are released…iMacs have 30-bits colour (ARGB2101010). Even cheaper monitors can do this. Now where’ s the software that can show/display ?
.
It seems that Photoshop rules in this department.

As a poster on another website/forum just said (and better than I can):

"…8bit/10bit is viewing bit depth (between your GPU and display). It tells how smooth gradients will be as there will be more colors in 10bit mode because there are no longer 256 gradation steps but 1024.

Another thing is archiving bit depth (document mode). It may be RGB/8, RGB/16, RGB32, etc. It determines how color data will be stored in file when saved.

So we may find ourselves working with RGB/8 document on a 30bit display and we also may work with RGB/16 image on a cheap 6bit+FRC display which is barely reaches 24bit with frame rate control.

As far as I know, Photoshop does support 30bit viewing mode. At least it does on my Mac system. Gradients are much smoother in this mode…"

I just wonder what the use is of a 30bit monitor. From what I’ve read the human vision can distinguish less the 10 million gradations. 30 Bit is over 107 million gradations.

It’s actually more than a billion colours.

Best explained on the internet:
30 bit monitor means 10 bits per channel, which is 210 = 1024. That’s 1024 colors per channel, so if we do the math 1024 x 1024 x 1024, that’s a total of 1,073,741,824 colors , which is 64 times more colors than a true color display
My iMac:

  • Bit Depth: 30-bits color (ARGB2101010)
    My Eizo:
  • (same)
    It’ s about colour nuances/ gradations being much smoother/ less banding/ more room in shadows/ etc.
    Still from 0-255, but steps in between are much smaller…so much easier to work/ more accurate. And yes…you can see that.
    More hardware (monitors/cables/graphic cards/etc.), can work with those colours, but it’ s no good, if I cannot see them (for editing/printing/etc.) That has to be done by the photo software/application. All part of a proper colour managed workflow.

Yes, 10 times more, 2 to the power 30.
But still the question: can one see it.

George

Yes, it’s clearly visible.

But how come when human vision can distinguish only less then 10 million colors. Is what you think to see maybe something else?

George

Hello George.
What do you mean by your second question;
“…Is what you think to see maybe something else?…”
It’s not about “thinking” to see.

In general (and very simply said), there is much more leeway when editing. Colours don’t break up easily like with a more limited number of bpc (and causing banding and other artifacts). Beside that colours can look more intense.

There’s ofcourse much information about this on the internet. Just a few articles, that may be interesting and go much deeper into this, than I can in this thread. But maybe you read these already (?).

Now iMacs can work with 10-bpc colours. Eizo can…and a growing number of monitors can. But….we do need software that can actually display this and gives room to work with it. Photoshop can. DXO PL can not.

Editing in 10 bit is something else as viewing in 10 bit. If these extra 2 bits are outside of my vision then they are useless for me.
Editing is already done in 16 bit. And when using a wider working space that number must increase to maintain the same quality

George

Well I use DXO PL for editing. And I want to see what effects edits have. Simple.
After editing, I saw banding. After same edits on a 10-bpc monitor and Photoshop, I didn’t; I “viewed” an image without banding.

@George I’m sorry to say this, but this isn’t just about you.

Just because you don’t have a need for this doesn’t mean others wouldn’t benefit from the feature.

@DxOStaffPO I feel you need to be more proactive in implementing this feature. It may not be a big enough issue for many users now, but the number of 10bit monitors is growing rapidly (and becoming ever more affordable). If you wait for user demand to be big enough to warrant developing this then you may have (metaphorically) missed the boat and will have had a lot of potential customers (and existing customers) choose an alternative editing solution.
