Blue/Amber Grad
The Blue/Amber Grad offers a classic graduated filter effect that can be applied to any
image in Photoshop. This is effect is most suited to sunny, blue sky landscapes such as
the photograph shown here. There are three types of Blue/Amber Grad effect. The
numbers indicate the ratio percentage of blue to amber color. So in the example above,
a Blue coloring layer is applied to the top 70% and an Amber coloring layer is applied
the bottom 30%. The Blue/Amber Grad ratios are: 50/50 and 30/70. The uppermost luminosity
control layer preserves the tonal balance of the picture.
