Introduction to PhotoKit Color 2.0 - Pixel Genius

Note: Roll your mouse cursor over the above image to see the indicated PhotoKit Color effect.
Blue Darken
Blue Darken/Blue Lighten
The Blue Darken effect is very effective at darkening blue skies and increasing cloud
contrast. It works by isolating the blue colors on two separate layers. The lower layer
contains the main Blue Enhance effect. The default opacity is set to 50%. As you increase
the opacity of this layer, the blue colors will darken and you should see more
contrast appear between the clouds and the sky. Above this is the Blue Saturation
layer. The default opacity for the Saturation layer is 25%. This provides a gentle saturation
boost to the blues in the picture. By adjusting the layer opacity you can make the
blue saturation stronger or weaker. The Blue Lighten effect will do the opposite and
lighten the blue content, not just skies, but any blue color that you wish to make lighter.
Blue Darken + Mask/Blue Lighten + Mask
The Blue Enhance layer is automatically masked during the PhotoKit Color process and
in most cases this does a very good job of deleting everything except those blue colors
we wish to see enhanced. If you apply the Blue Darken + Mask or Blue Lighten + Mask
effect, the mask is preserved as a layer mask, which masks the Blue Enhancement
layer (the Blue Saturation layer does not require a mask). The reason we provide this
additional effect is that some users may prefer to edit the mask to fine-tune this Color
Enhance adjustment.
