To adjust hue levels with the Colorama effect
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 Optionally, animate the Phase Shift control to cycle the hues in the image.
5 Optionally, choose an animated gradient layer from the Add Phase menu to modulate the hue.
To adjust lightness levels with the Colorama effect
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.
Input Phase controls for the Colorama effect
Get Phase From Specifies the property to which the Output Cycle is applied. Select Zero if you want to use a property
from another layer.
Add Phase SpecifiesthelayercontainingthepropertythatyouwanttoapplytotheOutputCycle.Tousethislayer
instead of the first layer, select Zero for Get Phase From; otherwise, this layer becomes a secondary property to the
first property. Add Phase From specifies the property to use from the Add Phase layer.
Add Mode Specifies how Colorama combines properties from two layers.
• Wrap Adds the values of the two properties for each pixel. A pixel cannot be whiter than 100%, so sum values
above 100% are wrapped around the cycle again. For example, a sum of 150% wraps back to 50%.
• Clamp Adds the values up to 100%. The sum of any two pixels that is greater than 100% is rounded back down
to 100%.
• Average Adds two pixels together and then divides by two. Average values never wrap or clamp, making this
option the safest choice for predictable output.
• Screen Screens the second layer over the original layer; the brighter areas in the second layer brighten the first
layer, and the darker areas in the second layer are discarded. Screen mode is especially useful for compositing fire,
lens flares, and other lighting effects.
Phase Shift Shifts the colors around the color wheel. If you animate Phase Shift, the modified pixels cycle among the
colors defined in the Output Cycle palette. A positive value moves the pixels in a clockwise direction; a negative value
moves them counterclockwise.
Animate Phase Shift to cycle the colors around the color wheel. Phase Shift is the parameter that is most commonly
animated.
Output Cycle controls for the Colorama effect
Use Preset Palette Specifies the palette for the color cycle. The top palettes are designed for quick color-management
tasks. The bottom choices offer a variety of built-in color effects.
Output Cycle Specifies the color palette you are currently working with. The triangles specify the location on the
color wheel where a specific color occurs. The color between triangles is smoothly interpolated, unless Interpolate
Palette is off. You can add up to a total of 64 triangles per Output Cycle.
