How to Use Channels in Photoshop to Fix Pictures
If you have a photo with a lot of shine and red eye because of the red channel being too high, you can fix it through Photoshop. Adobe Photoshop uses color channels to store color information about an image or to store selections. To fix errors, all you need is to have Photoshop C4 or C5. Photoshop has the photo and paint tools you need to fade most of the shine on your photo for a picture-perfect photo.

Scroll to "File," and click "Open." Choose your photo file, and click "Open" again. See if the red channel on your image is 255 or more by clicking "Window" then "Info." Move the cursor over the image, and the red channel will show how much red is in the image. If the red channel number is too high on certain portions of the photo, create a new layer by pressing "Ctrl+Shift+N" and click "OK." If you want to name the layer, type in the desired name and click "OK."

Select the "Brush Tool" or press "B." Lower the opacity and the flow to 15 percent by clicking the "Opacity" and "Flow" drop-down buttons on the top toolbar. Click the color picker tool for the foreground color. Use the color picker tool to click on the part of the skin or object that is slightly darker than the shine in your photo. This will create the new color on the color palette.
