Run this first to see which Channel to use as the Controlling
channel. It will create a new window showing
the 3 Lab channels side by side as they will be used in the following 'Auto
By..' actions. Delete this image when you have inspected it. |
Auto By Lch |
These 3 actions will create the
Layers using either the L, a or b channel to control
the adjustments. They will give you the option of blurring the
channel, which may be necessary for a or b, to get a smooth
transition of colour. The actions include an AutoLevels adjustment
on the controlling channel to make sure the entire width of the curve
dialog is useable. If you do not like the result, then use the 'Manual
By' actions. |

Auto By B ch |
Lab>RGB |
This action will convert the Lab image back to RGB for you. |
Auto all 3 chs |
This action creates 3 sets of adjustment layers in case you
need different controlling channels. Rus uses this, but being simple
minded I tend to just play with one adjustment at a time. Note this
must be started when the image is already in Lab mode. |
Flat Curve |
This creates a grouped Curve adjustment Layer and sets all
the 3 channel curves as horizontal lines. |
Zoom |
This creates the (zoom) layer which is normally needed to
allow sensitive adjustments. You will only start to play with this
layer when you are comfortable with the technique. |
