Blocks Blend Mode

For blend mode to work it requires at least two image blocks one on top of the other. Order of print is important.

Black and White Image Example:

Create a block named Image and set its Blend Mode to Saturation. Add Order = 1

Create another block named Mask and set its Blend Mode to Saturation as well. Add Order = 2

Use any image for the first block and use a gray-scale gradient fill image for the mask, as shown
