SAMPLE ALL LAYERS
This button is useful if you
are working on a multi-
layered document: you
won’t need to target a
specific layer, but rather
make the tool behave as if
it’s working on a flattened
version of your image. With
this unchecked, you need
to make sure the right layer
is highlighted in the Layers
Panel before you make a
selection. (Hold Cmd/Ctrl
and right-click over part of
the image to view all the
layers at that point.)

AUTO-ENHANCE

After making an initial

selection, the edge will

usually be hard and jagged.

It’s often essential to

improve the edge to make

it more precise – especially

so if the subject has hair, fur

or feathers. Auto-Enhance

automatically improves the

selection edge as you paint

• but it can drastically slow
  down the tool. Often it’s
  best to turn Auto-Enhance
  off, and instead bring the
  selection into Select And
  Mask afterwards.

FROM SELECTION TO MASK

Our selection here follows a

simple routine. Click Select

Subject, then paint over

the tree with the Quick

Selection Tool, then run the

selection through Select

And Mask. Now convert

the selection into a Layer

Mask with the Add Mask

button in the Layers Panel.

This hides everything

outside the selection and

removes the background.

Now you can simply copy in

a new background, and the

replacement is made!
