How to use Layer Masks
Layer masks are a useful way to
adjust transparency of Layers without losing any
image data. This tutorial will explain how to use
1. I am going to make a new
image and fill the background with blue.
2. Then I am going to copy an
image of a grid on top of this image as another
layer. You can use any image. Your layers pallete
should look something like this:
3. Now click the layer mask
button to add a layer mask to layer 1.
4. In layer masks, anything
painted white will be opaque, while anything
painted black will be transparent. You will
notice that the mask is already white, and that
you can see the top layer.
5. Now with the paintbrush,
paint some black. What happens? The black parts
become transparent and you can see the blue.
6. This is why layer masks are
useful. You can make things transparent without
actually erasing any data. If you make a mistake,
you can fix it by painting it over with white.
Now, use the gradient tool to make a black to
white gradient across the picture.
