Beyond Basic Photoshop: Using Levels
Written by Bill Hankins
Correcting a poor exposure
After making the selected image the correct size and resolution, do the following:
- Open Levels
- Select Channels
- Select Red and move the shadow (left) and highlight (right) triangles to where the histogram begins to ascend.
- Select Green channel and do the same.
- Select Blue channel and do the same.
This should be enough 99 percent of the time. If not, go to Levels RGB and adjust the midtones (middle triangle) just enough to correct facial tones, for example.
