Miniatures. This term is running around in my head as I search for a word, or words, to describe my work. Miniatures are found in illuminated manuscripts and also are water color paintings and portraits done on ivory.
How about Photographic Miniatures in this digital age? Big is not always better.
Photistic is a descriptive term I like also, and photism. Photistics (I created this noun from the adjective) may be perfect.
