*Layer masks are a fundamental tool in image manipulations.They allow you to selectively modify the opacity (transparency) of the layer they belong to.This differs from the use of the layer Opacity slider as a mask has the ability to selectively modify the opacity of different areas across a single layer.
*This modification of a layer’s transparency through a mask is non-destructive to the layer itself.
*This flexibility to define the opacity of different areas of a layer is the basis for more interesting image manipulation techniques such as selective coloring and luminosity masking.
*Working with Layer Mask is not easy, you need to be careful on using it.
*You can use this in your future if you want to be an entrepreneur you can use this for your own brochure/flyer.
