Brightness/contrast/gamma
Twiddling the brightness, contrast and gamma controls rarely
improves a picture. It's easier to search the web for a better
graphic, but you can't always find one. If this twiddling does
improve a graphic, it's worth putting into the public domain.

All of these pictures were too dark. Brightening them revealed
more detail. But you can't just turn up the brightness and get
a good result. The trick is in juggling the brightness, contrast
and gamma controls. The Oddie Children is a compromise: the
boy's suit is navy blue, but if you bring up its colour the girls'
faces and light dresses become too bright and lose detail. The
best result is Poynter's Andromeda: revealing her bonds and
pudic hair adds to the drama of the scene by making her more
vulnerable. Also, Poynter's signature and date are revealed.
