How to Select Non Transparent Pixels in Photoshop

 

 

Layers are usually a combination of transparent and opaque pixels. For instance, you may have an image of a masked ball. The ball is opaque and the remainder of the layer is transparent. Using this method you can quickly make a selection of the ball.

 

Step One

Open an image of a single masked object in Photoshop (File > Open).

Step Two

Open the Layers palette (Window > Layers).

Step Three

Cmd (PC-Ctrl) click the image thumbnail in the Layers palette. Notice the marching ants. Your object is selected.

Levels of Transparency

The pixels range from transparent to opaque with 254 levels of opacity in-between. Your selection captures the 256 levels of opacity. Level 0 is opaque, level 128 is semi-transparent and 256 is transparent.
