Adjusting lightness or hue levels using the Colorama effect

The following procedures provide two methods of adjusting the levels of an image:

To adjust hue levels:

1. Expand the Input Phase control, and choose Hue from the Get Phase From menu.
2. Expand the Output Cycle control, and choose Hue Cycle from the Use Preset Palette menu.
3. Expand the Modify control, and choose Hue from the Modify menu.
4. (optional) Animate the Phase Shift control to cycle the hues in the image.
5. (optional) Choose an animated gradient layer from the Add Phase menu to modulate the hue.

To adjust lightness levels:

1. Expand the Input Phase control, and choose Lightness from the Get Phase From menu.
2. Expand the Output Cycle control, and choose Ramp Grey from the Use Preset Palette menu.
3. Choose Lightness from the Modify menu.
4. Add a triangle to the Output Cycle at 3 o'clock and another at 9 o'clock, and then drag them toward 6 o'clock. This setting expands shadows and highlights while compressing the midtones of an image.
