Channeling Images

Getting images to look the way you want can be made a whole lot easier by using channels and masks. Channels give you access to each of the primary colors, allowing you to fix color casts, grainy skies, and other problems. But there's even more: channels let you composite several images together, so you can show what great friends you are with the rich and famous, or, even better, you can generate a decently-exposed photo from one that has the subject backlit by a window. Take a look at http://www.troutcom.com/gdtpug/backlitexample.html to see what the problem is. This is something that cannot be successfully handled by brightness and contrast, or by levels. A person really skilled in using curves can get close, but channels are the fastest, most flexible, and satisfactory approach.

If you aren't using channels because they are too complicated, you are making much more work for yourself by avoiding them. Come to the meeting and learn how they can make your job much easier, and how easy they are to use.

Remember, the meetings are free and open to the public. Please bring a friend.

Please send email to gdtpug@troutcom.com with suggestions for topics you are interested in seeing covered. Or even better, volunteer to give a presentation!

The Goleta DeskTop Publishing Users Group is a SIG (Special Interest Group) of the Santa Barbara PC Users Group. We are not platform specific: some members have PCs, some have Macs, some have both. Linux and other systems sprinkled in there for good measure. We focus on the issues of publishing in all forms, be it on paper, web, CD-ROM, or some other medium.
