The
Color Lookup Adjustment Layer
will help you to simulate the look of specific film
types as well as quickly create specific looks. For example, you can take an image that
was shot at high noon and make it look like a night scene. This panel also has a variety of
abstract options to please the artist in all of us.
This concludes the
Color Values
group of adjustment layers.
The final group of adjustment layers is a miscellaneous group.
Invert
— creates the equivalent of a film negative based on the image.
Posterize
— creates an image that looks like a poster.
Threshold
— fine tunes histogram to create a B&W image that can be used as a layer
mask. This mask can then be used to separate highlights from shadows or even fine tune
colors. This topic is beyond the scope of this topic.
Gradient Map
— replaces the standard B&W gradient used for histograms with a different
gradient. It can create some very abstract images.
The final choice in adjustment layers is called
Selective Color
and is a bit too advanced for
this topic. The explanation would be very involved but is not critical to our discussion at
this time.
