10-bit color support in Lion?

A Mac Pro with Radeo HD 5870. A Mini Display port output. A 10-bit display (e.g. NEC Multisync PA301W).
All the hardware pieces are in place to be able to display true 10 bit per channel colour depth from within Photoshop CS5.5.
But is the OS support there yet? My understanding is that previous versions of OS X did NOT support 10-bit color; but I have been unable to find out if Lion does. The tech specs posted for Lion are... erm, somewhat simplified.
Can anyone chime in and let us know what the status of 10bpc support is in Lion?
Thanks,
Jeremy

It hasn't been working for a while. I think it worked in CS4, but I don't have that installed now. This is with an ATI Firepro v4900. At least ATI finally fixed their Screen Capture bug. Adobe doesn't say much about the issue.

Photoshop CC 2104 30 bit Color Support

I'm using PS CC 2014 on a Windows 7 64 bit system with an Nvida Quadro 600 graphics card. I've tried every possible settings combination for PS and Windows 7 with no success using the AMD Ramp test file. The Nvida 10 bit Demo works fine. PS CS6 works as well, but only at 64% Zoom view and higher.
https://forums.adobe.com/message/7154720#7154720
Is anyone using an Nvidia Quadro 600 (not K600) card with Windows 7 having success with 30 bit color mode in PS CC 2014? This card is listed as "tested" in the PS CS6 GPU FAQ, but not on the PS CC 2014 GPU FAQ. I'm assuming it wasn't tested because it's an older card, but still should work.

Read that and the Nvidia PDF multiple times. Basically there's nothing you need to change in the Nvidia driver or Windows 7 Aero mode, but I have tried it in both in Windows Basic and Aero modes. It's "partially" working in PS CS6 and the Nvidia demo works so clearly my NEC PA272w monitor, Nivida Quadro graphics card and Windows 7 are supporting 30 bit color....just not in PS CC2015 and only partially in PS CS6.
I'm not a newbie at this stuff, so feel free to talk techie. Thanks!

16-bit color support

I have PSE 6 which has limited support for 16-bit color images. Does PSE 8 now allow images to be edited using 16-bit color depth?

It's basically the same in PSE 8.

Does Lightroom 4 support 10-bit color?

Hoping to learn if Lightroom supports 10-bit color. I know it supports ProPhotoRGB and 16-bit image files. Thanks.

Actually, the previous answers were only partially correct w.r.t. to displaying 10-bit colors. In contrast to what was said, LR4 (I use version 4.4) supports 10-bit colors, however only in the develop module. The library module does not seem to support it which could be because 1) it really does not support it or 2) the library previews are created with lower color depth or 3) something I haven't considered
I first read this somewhere and then personally verified it with ATI's ramp.psd test file on an Eizo CG276 (and a V4900 FirePro).
The library previews are jpeg (8-bit).

Macbook Pro & Mini Dispalyport Does NOT Support 10 bit Color Monitors

I am extremely concerned regarding Apple's Mini Displayport. Mini Displayport has been out for a year now, and is the video out port with the maximum signal output on Macbook Pro's. Apple's Mini Displayport still does not offer the compatibility and performance, that is possible with the standard Displayport implantation on Windows.
Case in point two monitors from NEC and Eizo, the NEC PA214W and the Eizo CG223W:
http://www.eizo.com/global/products/coloredge/cg223w/index.html
http://www.necdisplay.com/Products/Product/?product=5a6621b9-e9c4-4f02-8542-e625 1364bf7c
All current Macbook Pro's with Mini Displayport are unable to support the 10 bit color that these monitors are capable of. This is unacceptable, and an example of Apple leading customers to believe that Mini Displayport, offers the same capabillities and performance as Displayport.
It is my understanding that on paper MBP's with the NVidia 9400/9600 are capable of outputting a 10 bit signal. They just do not at this point in time, unlike all PC notebooks with Displayport. Mini Displayport has been sold by Apple as being every bit as capable only smaller than Displayport. The truth is it is not.
Apple notebooks can not currently produce the same level of quality on these monitors as Windows notebooks with Displayport that have also been on the market for a year now.
http://www.tftcentral.co.uk/newsarchive/19.htm#10-bitips

Displayport:
http://www.displayport.org/consumer/
http://www.displayport.org/consumer/?q=content/faq
"Performance for a display interface is really bandwidth. So Displayport offers up to 10.8 Gigabits per second. That bandwidth can be allocated for greater color depth (more colors per pixel, i.e.. 30 bit color monitors), it can be allocated to resolution, i.e.. WQXGA , or refresh rate."
Note: The bandwidth has increased to 21.6 Gbps with the announcement of Displayport v1.2.
It appears to me that aside from the top of the line (Windows PC) notebooks, that the only systems that will currently be able to achieve 30 bit color with these monitors are going to be desktop systems with Displayport/Mini Displayport and the necessary GPU and Operating System. This is an example of the difficulty in getting accurate information when it comes to what a system can and can not do. Rod correctly pointed out that I was mistaken in saying that "all" PC notebooks with Displayport are capable of achieving 10 bit per channel output, some do not. As BSteely, Lewis, and Rod have discussed Mini Displayport is not what is responsible for the fact that Macbook Pros can not currently output 10 bit per channel signal. Displayport exists and allows for this capability, and I stand by my opinion that currently Macbook Pros with Mini Displayport do not implement the full Displayport spec, in particular the ability to output 10 bit per channel signal to 30 bit color monitors. On the PC side it is the "workstation" class notebooks that have had and continue to have this capability. There may be others, but in reviewing Dell, HP, and Lenovo I am only finding it in the Precision, W series, and Elitebook models. The latest T Series Thinkpads with Quadro GPU's may work as well. At this point, I am not going to research each and every model to determine exactly which notebook models and configurations will work, except to say none of them are Macbook Pros. The lesson here should be get multiple confirmations regarding your system's configuration and your intentions in its use. I was mistaken in my understanding that the MBP 17 with Mini Displayport would support the Displayport spec as it relates to 30 bit color monitors. I have stated what I think is wrong about that, but that is the way it is for now. Apple is not the only company to hype a technology, only to offer a limited implementation of it. "Vista Capable" comes to mind.

This post will hopefully alert others to this limitation. To end on a positive note, in my experience the last six months with my Macbook Pro, Apple has demonstrated it can resolve issues quickly and effectively, and I have been extremely pleased to the extent that they have worked with me to address the few significant issues that have come up, including a system replacement in quick order. This may or may not be something they will be able to address with the current Macbook Pros or even the next generation. We will see.

Does Illustrator CC 2014 support 16-bit color?

I'm trying to create a grayscale image using RGB. The RGB components can only go up to 255. Does Illustrator support 16-bit color so I can have a range of 0-65535? I could not find this info in the documentation. A range of 0-255 is not enough for me.
Thanks.

No, it does not support 16bit. You can try to place a 16bit psd, and you will get a message, that it will import only a 8bit image version because Illustrator does not support 16bit images.

30-bit "Deep Color" Support lacking?

Well, I just manually set my display depth to 30-bit, I have a Dell U2410, which supports 96% of the adobe RBG spectrum, at 1.07bn colors, and 30-bit deep color. I have a graphics card with HDMI 1.3, and am connected via HDMI.
I'm using a GTX 460, and may I just say that things don't look right.
Every GTK application has a blinds-like transparency to them on flat menu surfaces (ex. Firefox's menu bar is semi-transparent with opaque lines through it, showing the background behind)
Non GTK Applications seem to render just fine (Chromium, for example worked great) Compiz limits the window rendering region to roughly 75% of the screen, centered vertically, this region is surrounded by a strange "blue glowing border"
I'll update this post with a screenshot in a second to better depict the picture, but am I alone on this?
Edit: Cannot take screenshots apparently, either... they just show up black.

moetunes wrote:How did you set it up to 30bit and why didn't you just go with the default 32bit ?
The default color depth in Xorg (and Windows, Mac) is 24-bit, with an 8-bit alpha channel ("32 bit");
This is 8 bits per channel, Red, Green Blue and Alpha (3 color channels, 1 alpha channel, 8bpc = 32 bits of information) this gives us the normal 16.7m colors.
In my case I have a monitor supporting 30 bit color, which totals 1.07bn colors
I set this in xorg.conf. DefaultDepth 30 and Depth 30 in their proper locations. The majority of things renders fine, barring things like images rendered via Feh, and GTK stuff. QT applications, and things rendered by my compositing window manager look fine, with the exception of the issue noted above. I'll try and obtain a screenshot using Compiz's screenshot plugin to better describe the issue and provide more information so I can hopefully get more input.
Thanks for the response.

32 bit color depth support

I'm operating from a Samsung Galaxy Tab 7.7, which natively supports 32-bit color depth. Is photoshop touch rendering at this level? or is it 16-24 bit color. not sure i could tell without comparing two images from actual screens.
basically from what i gather, the answer is at that photoshop touch, in its ability to render psd, jpg and png is at least using a color space providing 24 or 30 bit color depth. the device's color space is capable of rendering 32 bit color depth.

How do I Convert a Tiff image to a jpeg without being FORCED to 8-bit Color?

I am an Artist. I have High quality TIFF images. When I convert the tiffs to jpeg it forces me into 8-bit color automatically. (Forget about 32bit - it will not allow me to jpeg that at all) The only way I can get back to 16bit color is to use the already SMAshed file and bring it up to 16bit. THIS makes NO sense. Once the jpeg is smashed, HOw in the world is it supposed to convert up again. ?? Then even though it says you converted the file to 16 -bit , the metadata refers still to the file as 8-bit.
On top of all of that confusion, One picture, for example, when supposedly converted to 16bit, gets much BRighter then even the original Tiff image. It looks good on one hand and over exposed on the other. I assume that is photoshop throwing in fake resolution, am I right?
Am I wasting my time with this imaginary 16bit conversion?
Is there ANY way to take that original Tiff image and convert it to 16bit jpeg without the Default 8bit? I have been trying all kinds of things. I even have asked my web guy. My web guy says that 8-bit is unexceptable for printing, even for web.
Could this have anything to do with my computer and scanner?
I have the iMAC OS X 10.8.3 (3.2 GHz) 8 GB memory.
And I also have an Epson Expression 10000XL graphic arts scanner capable of scanniing at 48bit color.
This color stuff Really matters! It MATTERS! I HAve FINE art files. I am already losing so much quality with the jpeg conversion. (which I am required to do for SmugMug, in addition to compressing all my files to 50mb or Under)
Anyone who knows anything that could help me would be much appreciated.
Aloha,
-Melissa

First of all jpeg is 8 bit only there is no way to save as a 16 or 32 bit jpg, just does not exist. Secondly people print in 8 bit all the time and most if not all web graphics are in 8 bit as that is the only way to view it as there is no 16 bit or 32 bit monitors to view it. All but a few pro monitors are 8 bit monitors.
If you care about the color gamut and want the full range of color that 16 and 32 bit provide, then why jpg? Jpg by its own nature throws out color just to compress, thats why it is popular on the web, because of its small file size not its quality. If you need 16 or 32 bit for anything it must be in a format that supports that color depth.
That being said a jpg image at 8 bit will display 16+ million colors, 256 shades of red, 256 shades of green and 256 shades of blue.
Now here is where I think your bit information is off. a jpg image is a 24 bit image that will produce 8 bits of red, 8 bits of green and 8 bits of blue.
The 8, 16 and 32 are per channel not total color information.
If the overall image was 8 bits, the image would be gayscale.

How to Create a Custom Color Chooser/Palette with 16 or 24bit Color Support

Hi All,
I need some help on how to create a color palette/chooser with 16 bit or 24 bit color options available
First setting up the context:
I am developing an application which allows designing some GUI screens by adding various controls.
Now these GUI Screens developed are compiled and downloaded into a series of display devices with each device having a different color support (For e.g. 256 colors, 16 bit, 24 bit and 32 bit).
Now according to the selected device i would need to provide the "Color Chooser" with only those colors that are supported by the device. SO I need to design a Color Palette(s)/Chooser(s) with 16 bit, 24 bit or 32 bit color options
Could anyone help me out on how to create such palette? A piece of sample code would be a great help
Best Regards

It is not that simple... reason I almost never use those old captions anymore but replaced them by shapes (much easier to format).
Have a look at the available captions: for each caption you'll need a bmp and a fcm file, and follow naming conventions. See:

Same 6 bit color? I bet it is.

Sadly, all we have for color depth in the tech specs is the same old 'support for millions of colors' which we know in the past to have been a total lie. All the laptop displays have been 6 bit color, 262,144 colors, period. A great article on 6 bit versus 8 bit color can be found at:
http://compreviews.about.com/od/multimedia/a/LCDColor.htm
The tech specs for the new laptops don't indicate any improvement.
And yes, the displays use dithering to fake millions of colors. Yes, all displays use mixing of RGB colors to fool the eye into seeing millions of colors. And yes, not one laptop display I am aware of, including PCs, has adequate color depth to allow any real color matching for professional use. Use a high end external display for color matching purposes. CRTs are still considered adequate if not superior for this purpose.

Umm...
Every laptop has 6bit colors. There aren't any 8bit laptop panels that Apple could use infact. Except for some very new 17" ones...
The thing is, 8 bit panels use more power and are regarded by most of the industry as overkill for laptops.
Anyway I repeat, there are no 13" 8bit panels in existence.
You want 8 bit color? Plug in a CinemaHD or a Dell VA or IPS panel.

How do I get CS6 to not distort color when using Lion and printing from Epson R2880?

Ever since I up-graded to CS5 , the color has been distorted. It is not an Epson Lion problem because printing from preview or iPhoto the color is perfect.
Adobe has known about this problem since January 23, 2012. Their help people have taken over my computer for hours at a time and not been able to discover the source of the problem
I thought they might have fixed it with CS6 but no luck I chose use CS4 settings because CS4 had worked.
I printed using Printer Manages Color and color matching, epson color. I selected the correct media. The prints came out dark. The yellows turned green and the greens turned blue/green, reds became dull and blues a bit dark.
This is most upsetting because I cannot afford to buy a new printer and ink. Also I should not have to buy new equipment because Adobe cannot make their product work correctly.

If the printer prints colors accurately from Lion apps,which it does, then the problem is in Adobe.
Uh...ok...then the REST of the FREE world is going down the tubes because obviously, Adobe has screwed up?
Some of us are using LR4 and CS6 to print and getting accurate and excellent results with Lion (10.7.3) so the question begging for an answer is why can't you?
Read very carefully what Chris wrote...the odds are REAL GOOD you are NOT using the correct settings...but since you don't bother to show or explain the EXACT settings you are using when printing, we'll never know. Will we?
If the vast magority of the user base is NOT having an issue, to what do you attribute the disconnect? User Error is the single most likely result...
You want help? Or do you want to argue?
I know a little bit about printing and I seem to be able to print with zero issues on a wide variety of Epson printers...you wanna place blame or do you wanna learn how to fix the problem? (clue, the odds are it isn't Adobe nor Epson leading to the problems, it's you bud).

Is the latest iMac monitor (21.5" and 27") using 8-bit color depth or 6-bit dithering?

So far, there isn't been an official answer. Support millions of colors could be either one.

My question is more toward the hardware on that iMac monitor rather than the software setting (32-bit).
I notice a similar discussion few years back:
https://discussions.apple.com/message/10643776#10643776
So seem that Apple is not using 8-bit colors yet on iMac?
