There are points in the Photoshop Learning Curve - that you can point back to and say: Oh - that's how you use that. Wow.
I can remember these points:
1) Adjustment Layers as opposed to working on the background layer
2) Related to that, getting a real feel for various blending modes, and going beyond that to only blending within a certain range
3) And during the last week: Layer Masks have really kicked in.
It probably came out of working with PhotoKit - especially in what they call the Creative Sharpener step - where they'd set up a black mask for you and let you paint the parts in that you wanted to reveal.
There were a number of times that I wanted certain areas to be sharped - but not others. And I began to get a feel for layer masks. Soon the adjustment layers - whether levels, curves - whatever - had their masks nicely feathered. Feathered, feathered, feathered. How much do you feather? Even that began to kick in when thinking in terms of the dpi of the print. If I feather this much I'm talking about 1/4 inch on the final print.
So you sit there and say, oh it would be nice if the foreground wasn't quite as sharped up as the background. In fact, that would look
more natural.
Or I'd love to just make some area less contrasty. The layer mask power is incredible.
I don't think that everyone hits the various Learning Signposts in the same order. But when you do - you remember the moment.
I suppose that I should have taken a course in PS and could have compressed the learning curve - but that idea never dawned on me. On the other hand, I do get the "rush" when one of these signposts hit me over the head.
