You may have detected a pattern to these posts in my non-destructive editing series, the last couple of weeks. Layers are everything. Fortunately for us, Photoshop thinks so, too.

Adjustment layers are yet another advantage to shelling out the serious coin for full blown Photoshop over it’s free and cheaper competitors. These special layers allow you to apply special effects to the layers under them. For example you can adjust the curves, add a custom black and white effect, adjust the brightness and contrast, the saturation, and much much more. The advantage to this method is obviously that the effect is completely reversible. Not so obviously, you can also go back and reedit the adjustment parameters at your discretion.
