Based on a YouTube video I saw recently, I just added this to Transformations.pdf:
Mixed Illumination
First take several photographs of the same exact subject but illuminated differently – either from a different direction or with a different color or brightness. You can then use Stack Images to adjust the relative amounts of each image which in turn lets you explore different combinations of the light sources.
