|Here's another example
where using SHIFT-click for multiple selections comes in very handy.
Let's say you have a task like the following: here's an image which
contains a multi-color, complex background image and also a simple logo
or text item on it. The logo/text has only a few distinct colors, but
the background is loaded with throuands of shades: perhaps it's a
photograph, perhaps a 3D rendering or sinply a drawn image with
gradients or other complex shapes and colors
The challenge is to extract the desired logo shape,
In this case, you may still be able to use the magic want, as long as
there are no colors in the background that are the same as the logo and
touching it. Even if it did, you could actually still use it, but might
need to 'de-select' some parts of the background which the magic wand
might bleed into where it sees the same color in the logo and the
neighboring background pixels.
this is a flat image: no layers. We're trying to re-verse
engineer the composition.

This example was actualy created in PD Pro, using the Sky render file:
menu: Filter > Render > Sky
and the text tool, rendering the text tool into alpha, and using
menu: Alpha > Expand alpha
Oh and I couldn't resist also destroying the bottom with some baddy
grass, a preset from the Particle
Perhaps we'll talk about how this was created in another tutorial.
Let's for now just take a look at how to extract the text portions from
