One fun thing was when I learned to composite, combining multiple images into a single photo, a technique that lends itself to lots of fun trickery.
My friend Mia McCullough was kind enough to come over and be my guinea pig, posing in three separate places on my couch, with a different shirt, different pose, and slightly different hair in each photo.
The result was an eye-popping triplicate of herself that led to a fun conversation about how great it would be to actually have three of oneself - imagine how much more you could get done!
