Ten Ways to Adjust Color in Photoshop Elements 11
Eliminate color with Remove Color.
With the Remove Color command, you can eliminate all the color from an image, layer, or selection. In the figure, the background was selected. To use this one-step command, simply choose Enhance→Adjust Color→Remove Color.
Sometimes, stripping away color with this command can leave your image flat, or low in contrast. In this case, adjust the contrast by using one of the many lighting fixes in Elements, such as Auto Levels, Auto Contrast, or Levels.
The Convert to Black and White command (under the Enhance menu) enables you to convert a selection, a layer, or an entire image to grayscale. But, rather than just arbitrarily stripping color (as the Remove Color command does), the Convert to Black and White command enables you to select a conversion method by first choosing an image style.
To further refine the results, you can add or subtract colors (red, green, or blue) or contrast by moving the Intensity sliders until your grayscale image looks the way you want. You aren’t really adding color; you’re simply altering the amount of data in the color channels.
