Photoshop Tutorial using Channels


Channels is a tool in photoshop that stores the color information of an image. It also stores the selections, which can help with manipulating graphic images. The photoshop software automatically creates channels when the user open or create a new image. The default channel setting is RGB or what we call the Red, Green, Blue composite channel.

In Photoshop, channels offer greater control and sensitivity in performing various functions like filtering, blending and retouching. It is used in applying spot colors on images. It also helps in converting Photoshop images from one mode to another with good result but less effort.

Photoshop supports a total of fifty six channels. All of these channels can be use but it is not advisable because the more the channel you use the larger the file size you get with your image. These channels can be controlled via the Channels Palette. They can also be given corresponding names of their own. You can select any channels by clicking the thumbnail of the channel or its specific name. You can also rename, hide and show the channels anytime.

What most users do when they used channels in their work, they duplicate the channel to utilize it efficiently. Also you can replace a channel in an image by copying the channel of the other image and pasting it to the channel of the image you’re editing. One other useful option in photoshop is the splitting of channels. Anyone can split channels from one image to another using a separate file. Sample of this is when you need to save a file in a format that does not support channels like EPS. The other useful option aside from splitting is the merging of channels. Merging channels can create certain special effect on a certain image.

Listed below are sample tutorials that uses channels in editing an image.

CS3
Photoshop CS3 is now at version 10 of this phenomenally successful program (well twelth actually, if you count versions 2.5 and 5.5). And it all started almost twenty years ago in late 1987, when Thomas Knoll with his brother John, created the first prototype version of Photoshop. Photoshop CS3 has come on a long way since then, so much so that even in a big book like this there is only enough space to cover the features that are of specific interest to photographers....
