This topic has come up before, and I read an article about it last night. For some reason (greed?) Adobe charges much more for its products for the Australian market. As a matter of fact, Aussies could get PS for less money by flying half way around the world to the United States. From Adobe, “If Australian customers don’t see the value of Adobe’s software, they can buy another company’s software” Robson said. “Alternatively, they can take a trip overseas or import the American version.”

And software companies wonder why software piracy is so common.

Make sure your layers-bin is open (Window -> Layers).
With an image open, Look at the icons in the layers-bin:
The one that looks like a page with folded corner, will give you a new, blank layer above the selected one. (To select, simply click on the layer).
The icon that looks like a half dark, half light circle, will give you a new adjustment layer above the selected layer. You will also have to choose what kind of adjustment.
The icon looking like a square with a hole in it, will give you a layer mask ON the selected layer.
The next two icons will lock all pixels, or lock transparent pixels - I don't know how to use them, as I never have.

To be sure, there also are keyboard shortcuts to work with layers, or you can go through the menu under layers, but to begin I think the visual aspect of the icons may be easiest.

(I use PSE11, but I believe these icons are the same as in PSE10).

Because he likes the attention you folks give him and it works perfect...........lol

My Op/Tech doesn't use the tripod mount hole. That allows me to carry around a very light weight tripod which sure beats carrying around one of my big heavy duty ones when I'm out walking for hours at a time. I admit my light weight tripod is not the sturdiest but I can keep the strap around my neck in case the tripod gives way which it did once. I didn't tighten the knob tight enough on one leg. Having the strap around my neck saved the camera.
