I have been using Photoshop since version 2.5, mostly for prepress and now web work. I notice a lot of folks mention the use of adjustment layers.
What is the advantage of using an adjustment layer as opposed to a duplicate layer? Is it just so you can undo a particular adjustment without undoing subsequent adjustments?
There also seems to be some DPC rules impact based on the types of layers used and how they are used.
Thanks in advance. |

-You can not just undo, but "adjust" the the adjustment at any time.
-You can toggle the effect on and off to preview the effect
-You can adjust the opacity of the adjustment layer to fine-tune the degree with which the adjustment is applied
-You can change the order in which the effects are applied by changing the layer stacking
-Etc.!!!
All of this with minimal increase in file size because you don't have to duplicate the pixel values by creating a copy of the background layer.
PS: For DPC, if you have a validation request, you have a permanent record of the exact values of your adjustments, so that the SC can duplicate your editing steps.
In Basic Rules challenges, the Adjustment layer must be applied uniformly to the entire image -- no selections or masks allowed -- and in "Normal" mode (there's a drop-down menu of mode choices).
These restrictions do not apply in Advanced Rules challenges.

Don't forget the other great thing about adjustment layers - you can drag and drop them to copy them from one image to another.
This means you only need to do the adjustments editing on one image in a sequence, then replicate it and tweak quickly and easily in the remainder.
