Masked Blend Max/Min

Masked Blend Max/Min blends two grayscale inputs with Max (Lighten) or Min (Darken) and creates a mask that displays the foreground and background areas according to the blending mode.

It works exactly like the Blend-Node, but provides four additional outputs:

- Mask Foreground - This output displays the area of the foreground input as a binary mask.

- Mask Background - This output displays the area of the background input as a binary mask.

- Blended Foreground - This output displays the area of the foreground input as a multiplied with the mask as a grayscale image.

- Blended Background - This output displays the area of the background input as a multiplied with the mask as a grayscale image.

This can be useful very useful, if you use it as a color mask to mask of the invisible areas of the background.

If you have any suggestions or comments on this filter, just let me know, what I can improve.
