Photoshop CS5: Any color with zero red information will turn black

I've been having this problem ever since I installed Photoshop CS5 (12.0.4) on a Windows 7 64-bit machine. I've used the program on a Windows Vista 64-bit PC in the past with no problems.
Any color that has zero red information will turn black when in RGB mode and in either 8 or 16-bit mode. If I use the paintbrush, for example, a color with RGB 0/100/100 will be black. However, the color 1/100/100 will not. This problem also occurs with imported images. I've only tried JPEG and PNG so far. The problem does not save out though, as any image exported from Photoshop will appear fine. The issue seems to go away when in 32-bit mode, but it's a little RAM-intensive, and the file sizes are quite large.
I have reinstalled Photoshop, reset its preferences, and reinstalled my video card's drivers (I have a Radeon HD 7870). My PC has 8 GB of RAM and plenty of free hard drive space.
Below is a screencap of what's going on. I'm a bit lost here...any help would be greatly appreciated!

It's a well-known issue with current ATI drivers and Photoshop's GPU-accelerated color-management logic.
You can work around it a couple of different ways:
1. You can install ATI's latest Catalyst 13.2 beta driver, which does solve the problem, or you can uninstall and drop back to Catalyst 12.8.
2. You can switch to Basic GPU mode (and restart Photoshop). Basic mode moves the color-management logic into the CPU. This might be a workaround you'd prefer to take until AMD releases their next non-beta driver where the problem is solved.

Photoshop CS5 not working with Lucida Grande Regular font

On my iMac Intel Core 2 Duo 2.66 GHz, I am running OS 10.6.7.
When using Photoshop CS5, if I try to use the font, Lucida Grande Regular, it causes an error.
"Could not use the type tool because of a program error."
When I try to open an existing file that has type layers that include the font Lucida Grande Regular, Photoshop will not open the file. I have several of these files that I want to use. I can open them on another Macintosh and everything works fine.
First I get a message window that says, " Some text layers might need to be updated before they can be used for vector based output. Do you want to update these layers now?" I click on update and then get the following message. "Could not complete your request because of a program error."
I have updated Photoshop CS5 to the latest version, 12.0.4.
I have run the FontTest.jsx script and it shows an error for Lucida Grande Regular.
(IOError: General Photoshop error occurred. This functionality may not be available in this version of Photoshop.
- <no additional information available>)
The other 100+ fonts on my machine did not create errors.
Since Lucida Grande Regular is an essential font for Mac OS X, I re-installed OS 10.6 in order to have a new version of Lucida Grande Regular. After that re-install I am having the same problems with the font not working in Photoshop.
It also does not work with Adobe InDesign CS5. The font does work in Microsoft Word.
The program Font Book verifies Lucida Grande Regular.
Other fonts including, Lucida Grande Bold, work fine in Photoshop and InDesign.
What can I do to get Photoshop CS5 to work with Lucida Grande Regular?

Wow, I'm so glad I found this thread. This problem has been dogging me for years, and it's so sporadic that I've been afraid of breathing the wrong way lest I somehow incur that diabolical Program Error dialog. I'd managed to reach a truce with Photoshop CS5, getting it into a barely working state, and avoiding all updates... until Lion came along today. Then I updated to CS5 12.0.4, and the Program Errors were back again.
Now I see that the problem does seem to be related to the Lucida Grande font. If there's a layer with that font in it, not only can I not edit that text, but I can't marquee select anything, nor drag any shapes. Deleting caches and massaging fonts are completely ineffectual measures... but if I delete the Lucida layers entirely, we're back in business.
At least so far.
Funny to think that of all the innovations I'd like to see Photoshop adopt, the fixing of this one issue is the thing I'd like to see most. I'll be keeping my eye on this thread, and any updates by Mr. Cox.

Raw files from the new Nikon D810 will not open with either Photoshop CS5.1 or Lightroom 4. When will a real Adobe solution be available to work with Raw (NEF) files in their native format, using CS5.1 and LR4?

Clarification: this is a user forum; you are not addressing Adobe here.
The answer to your question as phrased is: never.
CS5 is history and it is not longer supported. There will not be any updates or bug fixes for CS5.
You need to convert the raw NEF files from your D810 to raw DNGs using the free, standalone Adobe DNG Converter 8.6 RC (beta), the first version ever to support that camera..

How to get Camera RAW / Photoshop CS5 to work with Canon 100D?

How to get Camera RAW / Photoshop CS5 to work with Canon 100D? I don't want to by this product again and again...

In what way is ACR not working in Bridge? Is there no right-click Open in Camera Raw available from Bridge, or there is, but the ACR version is less than ACR 6.7.1 or what exactly is the issue?
Also, if you open Photoshop and do Help / About Plug-ins / Camera Raw, is ACR missing from the list, or if not, what version does it say is installed?
You might also want to describe what methods you have tried to correct the issue, since saying you've tried what you've seen posted and they didn't work, isn't really much to go on.

How do I save an image (logo) transparent so that it will appear transparent on any color background such as a gradient or black?

How do I save an image (logo) transparent so that it will appear transparent on any color background such as a gradient or black?
I save image as "transparent" at File > New... but when I place on a gradient background it keeps appearing white. I'm trying to save transparent to be effective on any color such as a gradient or black. How do I truly save as transparent?

Put the logo on its own layer set the layer fill to 0 and add a layer style to the logo layer. Here I duped one change fill to 0 added style.

I'm sorry to learn that your phone is having problems starting up, marinema08. I'm sorry if this is incorrect, but are you using the original HTC Droid Incredible or a later Droid Incredible model? Please try placing your phone in Safe Mode to see if you are able to move past the Droid eye. http://vz.to/1kdQWVI If you are able to enable Safe Mode, please try deleting any recent applications you have added.

You need to plug the iPad into your computer that has iTunes installed on it, and activate it.

Photoshop CS5 building Histograms with every file change

I am working in Photoshop CS5 on a MacPro with Snow Leopard, 10.6.4. I have a file that is a little over a gigabyte open. Every time I make any changes to the file (i.e. select a different layers, grab the text tool, etc.) a menu pops up with a progress bar and says it is building the histgrams. This process happens with EVERY move. As you can imagine, this has slowed my productivity down to a crawl. Can I do anything to make it stop rebuilding the histograms at every step?

Photoshop CS5 ruining color now?

Hi all.
I captured a screen shot on my Mac using Grab, and pasted it into Photoshop. The color was way off, with a pinkish cast added. You can see a comparison here; the original is on the left and Photoshop is on the right.
I brought this split-screen shot into PS and the cast got even worse. I tried both TIFFs and PNGs, and Photoshop is wrecking the color. I can't find any explanation in the settings. Any ideas? PS is pretty much unusable at this point.

Mobius Strip, discussing the profile of screen grabs is all distracting twaddle…
Since you don't seem to be aware of this, your Color settings are located here Edit > Color Settings. You need to make sure these settings match in CS4 and 5, and that no "Convert to…" settings are switched on in either. 'Convert To…" will automatically convert opened documents to your default profiles, specified in this dialog. Which you don't want.
You need to develop some basic understanding of Color Management.
what is Photoshop displaying when "proof color" is off? Because it's not what other apps are showing from the same files.
It is attempting to display the actual colors contained within the document. Whatever profile that document may be in. It uses the monitor profile, which it assumes to be accurate, to do this. This attempt is restricted only by the full gamut (range of colors) available on your monitor.
There were no changes to Color Management features between Photoshop CS4 and CS5. In every resect they will display colors the same. To be 100% sure than Photoshop is behaving the same in both cases, make sure also that Open GL is consistently switched on or off for both versions.

Photoshop CS5 - Compatibility issue with nested groups

I'm using Photoshop CS5 to create a multi-layered, group-heavy PSD. The final file is intended for public consumption, so, ideally, I'd like it to be accessible to as many users - and therefore compatible with as many versions of Photoshop - as possible.
However, I just tried to save the file, and was prompted with this message:
This document contains nested layer groups that may change in apprearance if opened in applications older than Photoshop CS5.
Opening the file in CS4 after the save confirmed that a few of the layer groups were indeed corrupt.
Can anyone shed any light on this?

It looks like you're the only person so far who's posted that particular message on the web anywhere!
Out of curiosity, do you have the Maximize PSD and PSB File Compatibility option set to Always in Edit - Preferences - File Handling?
I have no experience with nested groups, myself, but that setting comes to mind as being involved with the kind of compatibility you're hoping to accomplish.
I do know that nested group capabilities have been around since at least Photoshop CS2.

Photoshop CS5 OpenGL support with latest Intel integrated graphics?

Intel's latest "Sandy Bridge" CPUs (Core i5 2500, Core i7 2600, etc.) included much-improved integrated GPUs, thus allowing for systems that do not require a discrete graphics card. Although not suitable for high-end gaming, the specs appear to be more than enough for Photoshop CS5's GPU acceleration needs. Can anyone confirm or deny that CS5 will be able to take advantage of the new Intel HD 2000 and HD 3000 graphics? The driver specs say it supports OpenGL 3.0 and Shader Model 4.0, both of which satisfy the minimum requirements of OpenGL 2.1 and Shader Model 3.0 for Photoshop CS5.
I'm 99% sure the latest hardware is supported, as Adobe's own document mentions "Intel HD Graphics", just not the specific model numbers. The document was also last updated in November 2010, before the current series of CPUs were released to the public.

Having implemented my own OpenGL applications over the past several years, I can tell you that it's absolutely not that simple. The word "surely" cannot be applied here.
Photoshop, in displaying 2D things with a 3D system, is NO DOUBT using OpenGL differently than any other application has ever used OpenGL. It's the nature of the beast. What they put in which type of buffers at what time in which mode using what calls in which order and using what performance features are all open choices. The software itself makes choices at run time about what parts to use based on OpenGL version and advertised capabilities. Plus they're using Shaders (on-GPU programming), and there are a bunch of different ways to get that done as well.
In order for a system to run perfectly, the applications and video driver / GPU subsystem have to get things exactly right all the time every time, and not just for Photoshop but for all the other apps (and Aero) as well. Though Intel and the others may do plenty of testing, what might work on a test bench might not work when combined dynamically with other things in ways that only happen on an end-user system. Note the number of video game bugs fixed in each driver release.
However complex you think OpenGL is, multiply that by 100 or more and you may be getting into the ballpark.

Photoshop CS5 Performance Problems with Optional Extension Plug-ins Installed

If you installed any of the Optional Extension Plug-ins in Photoshop CS5 (they aren't a part of a default installation of Photoshop CS5) - we determined that some users have had serious performance issues due way these Optional Extension Plug-ins were installed on Mac systems.
We have created the following knowledge base document to help users determine if they are affected by the use of these plug-ins. The document contains instructions on how to remove the plug-ins and restore your Photoshop prefs:
http://kb2.adobe.com/cps/889/cpsid_88974.html
Note: It's important to both remove the plug-ins and restore your Photoshop prefs in order to get back to a 'good' state.
