Photoshop Masking & Compositing by Katrin Eismann:

The easiest way to create a mask for an image like this is to go to the
channels display.  Duplicate one of the channels.  Doesn't matter which one.
Call it mask or foreground mask or whatever descriptive name suits your
fancy.  Now, with only that channel selected, call up the levels dialog.
Slide the left-most triangle to the right.  You'll see the shadows block up.
Drag the right-most triangle to the left.  You'll see the highlights blow
out.  Keep doing this until you're left with mainly a black foreground and a
white background.  It won't be perfect, but it will be easy enough to clean
up the area with a large paintbrush.  The border between the two is what you
want to make look good.  Might want to do a small blur to this mask just so
there isn't an abrupt cutoff between black and white.  Then, you can use
this channel as a selection.  If you select this channel and then add a new
fill or adjustment layer, this selection will automatically be part of the
layer mask.

That should get you started...
