Alpha in Photoshop


Alpha in Photoshop

When we want some part of an image to be visible than we create an alpha.  Alpha works on black and white color. Black goes transparent and white goes opaque. We save alpha on 32 bit and file format is targa.

Step 1:- Open an image in photoshop.

Step 2:- Select the area which you want to make visible (opaque).

Step 3:- Now go to channel and click alpha button to create alpha.

Step 4:- You can check your alpha.

Step 5:- Now save as a targa file at 32 bit.
 Your alpha is ready.
