how do you mean "understand channels",
if you mean how channels work well i can't really tell you....
because im no expert on that area....

[Tamlin]

The whole area of Channels is quite involved - in fact, there have been whole books written just about Channels in Photoshop. If you can be a bit more specific about what exactly you want to understand, I'm sure someone here will be able to help.

Saying you want help 'with channels' is like saying you want help 'with photoshop'. You need to be specific with your requests, or we will not know how to help you!

PS. For the basics, try reading the manual and included help docs with Photoshop.

YOU ARE RIGHT
I JUST WANT SOME TOT HELP ME TO IMAGINE HOW IT WORKS

OK, let's try a different approach.

When you load an image in Photoshop, it is composed of a number of "channels". How many depends on the image mode: RGB images are composed of 4 channels - Red, Green, Blue and a composite of all 3. CMYK images have 5 channels: Cyan, Magenta, Yellow and Black, plus a composite. Indexed colour, Duotone and Grayscale have just one. Each channel holds information about a particular colour element in the image. You can think of individual channels as being like plates in the printing process, with a separate plate supplying each layer of colour.

But it doesn't stop there. The Channels palette can also contain alpha channels, which have a number of uses. One of the most common uses is to store selections or paths so you can use them later.

Channels can be edited individually so you can blend certain ones, or alter the colour of just one channel. You can also achieve interesting results by applying filters to just one channel.

So to sum it up, channels are a useful tool when it comes to colour management or using (and reusing) selections. If you look at some of the tutorials that deal with these subjects, you'll probably find examples of channels in use, which may help you to understand what you can do with them.

I just did a quick search and found these...

This 4-page article was written about channels in Photoshop 6, but most, if not all, of the information still holds true for all versions up to and including CS2:

thank you very much tamlin
i begin understand

[Tamlin]

No problem - as it says somewhere else here... "Every journey begins with but a single step..."

[unleash]

i thought that was a chineese emperor or filosifer......
but if someone here said it he/she must be or very old(like more then 2000 years or she /he must have read it once....)

[Tamlin]

I think it was Lao Tzu, the Chinese Taoist philosopher, who originally said "The journey of a thousand miles begins with one step." - only he said it in Chinese, of course!

How to put this simply...

Channels are basically how Photoshop identifies the density of colors and shades in a document. For example, let's just look at the Blue Channel (in RGB mode). The darker the area is, the more blue there is in that area. Completely white means there is no blue there.

Hope this helps a bit. Scott Kelby wrote an entire book about Photoshop Channels even.
