Alpha channels are basically specialized selection processes. Alpha channels are used to make, store or edit selections made using tools such as Lasso, Magic wand or Pen tool.
Alpha channel is another type of image masking. When we say mask, it is an 8-bit channel using 256 levels of Gray, ranging from 0(black) to 255(white). With that being said, alpha channel is a masking technique which defines a selection in black, white, and varying shades of Gray pixels. White acts as the selected pixels; black acts as the unselected area and the levels of Gray define what is partially unselected or selected depending on your view point.
Here you will learn how to mask out hairs or in this case fur using the Alpha channel technique. Let’s begin:
Open the image of your choice, select the pen tool and make a clipping path on the part of the image you want to edit. If you’ve noticed, I have two images with the labels “1” and “2”. This represents the two clipping paths I’ve made for this image. For the image with the label “1”, I did a clipping path on the inner part of the hood. (Notice the faint clipping path line).
