Do you REALLY know what Adjustment Layer is? This video may surprise some of you. When I noticed some strange behavior of Adjustment Layers - I found out that I didn't understand what they really are. After some research I figured out that trusting the well known definitions of some things may be misleading in some cases. This video will not teach you any new sophisticated ways of using Adjustment Layers, but may help to better understand the way they work. Have fun.
