A basic explanation of the technique used in my "Stamp-based filter" project. Use the arrow keys or click the right and left of the background in order to navigate forward and backward in the explanation!
Find the original project here: https://scratch.mit.edu/projects/316673077/ A note: As I was finishing this up, I realized that you can probably omit the dedicated white layer, because the brightness effect can be applied to the hue layer in order to control saturation as well. However, the stamp-based filter project uses the three-layer version, so I'm taking that as an excuse to leave this project as-is!
