Photoshop CS2: Altering Images
Photoshop CS2: Retouching in Channels
In the last tutorial, Linda explained how you could alter your images with levels and curves through adjustment layers. In this article, she shows how you can retouch your colour images through colour channels. This option allows users to change values, tones, and colour through channel modifications. An added bonus is that artefacts, or blemishes, can be reduced through the colour channel option as well. And, when that option doesn’t work, you can use colour channels to pick the best option for a black and white photo…
Colour Channels: The Hidden Realm
Many photographs might call for simple adjustments to the overall picture, such as a simple tonal and value alteration in photograph below:
The image at left was a little too dark in the shadows and the owner wanted to emphasize the filly a bit more. I brought up the mid-tones and reduce the shadows with the simple addition of a new adjustment layer for levels. Now the horse is more vivid and the details are more solid in the horse (more about adjustment layers and levels in the previous article).
But, other photographs – like the 1960’s era photograph below – call for more detailed work, and a simple adjustment layer just doesn’t cut the cake. The image below, for example, was altered with the same method that I used above with the following results:

Linda Goin carries an A.A. in graphic design, a B.F.A. in visual communications with a minor in business and marketing and an M.A. in American History with a minor in the Reformation. While the latter degree doesn't seem to fit with the first two educational experiences, Linda used her 25-year design expertise on archaeological digs and in the study of material culture. Now she uses her education and experiences in social media experiments.
Accolades for her work include fifteen first-place Colorado Press Association awards, numerous fine art and graphic design awards, and interviews about content development with The Wall St. Journal, Chicago Tribune, Psychology Today, and L.A. Times.
