OPening layers palette

[almichaud]

I scan an image-I click on layers tab-the small window opens but the opacity, lock windows are grayed out and there are no A_B+C_D etc. Just one small window?

Almichaud,

That's because the single layer is a background. Backgrounds have limited
functionality (to protect them, I think...)

You can convert the background to a layer by double-clicking on it in the
Layers palette. Then the items you mention would no longer be greyed-out.

I would recommend, however, that you leave your background intact and,
instead, work on a copy of it as a layer.

You can do this via the menu (Layer -> Duplicate Layer), or the Layers
palette (click-drag the background to the "new layer" icon at the bottom of
the palette... the center one that looks like a small square with one
corner turned up), or, also in the Layers palette, right-click on the
background and choose Duplicate Layer from the context menu (don't fiddle
with the Destinaton portion of the dialog).

HTH,

Byron
