Why is the Gamut Warning unavailable?

Added on Tuesday 27th of February 2007 01:26 am EST
 

Application:

Photoshop CS2

Operating Systems:

Macintosh, Microsoft Windows

 

All of a sudden, I noticed the Gamut Warning option is grayed out, I can’t select it to turn it on. I’m working on a Macintosh in Photoshop CS2. Any idea how to fix this?

 

That sounds like an issue with corrupt preference files. Preference files corrupt easily and often are the culprit of many weird anomalies in Photoshop, such as menu items not available, as you just described.

 

To reset your preferences:

1.       Quit out of Photoshop.

2.      Relaunch Photoshop and immediately press and hold [command] [option] [shift] ([Ctrl] [Alt] [Shift] in Windows) until you receive a dialog box asking if you want to delete the Adobe Photoshop Settings file.

3.      Click Yes.

 

One word of caution is it also resets Actions, tool presets and color settings. If you want to delete just the preference file you’ll need to locate it on your machine and delete it manually. (Don’t forget to quit out of Photoshop first, though.) Depending on your operating system, the file is located in different places, but here are a few configurations that should help to point you in the right direction:

 

Save an image’s channels as individual files

by Amy Palermo

Application:

Adobe Photoshop 7/CS/CS2

Operating Systems:

Macintosh, Microsoft Windows

 

I’d like to save an image’s individual CMYK channels as separate files. My method so far seems like a lengthy process, though. I’ve been deleting all of the information in the C, M, and Y channels to save out the Black channel, and repeating that for each individual channel. Is there a quicker way to do this? 

 

There sure is! Photoshop has a feature that will split one image into individual images—one for each channel in the image.

 

To split channels:

 

1.       Open any flattened CMYK image, such as the one shown in Figure A.

2.      Select Window > Channels to display the Channels palette.

3.      Choose Split Channels from the Channels pop-up menu. This separates the image into four individual images, as shown in Figure B.
