How to Use Channels in Photoshop to Fix Pictures
- 1). 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."
- 2). 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.
- 3). Use the brush to paint in the color of the object to cover up the shine. Paint very slowly. You should see the shine disappear, and the image should look natural.
- 4). Fix red eyes in your photo by mixing in more green and blue channels. Press "Shift+M" to select the elliptical marquee tool. Use it to draw a circle around one of the pupils. Click "Image" then "Adjustments" then "Channel Mixer." Choose "Red" under "Output Channel." Under "Source Channels," Change the red channel to 0. Type in "50" for the green and blue channels, and click "OK." Repeat the step for the next pupil.
