Flash

The term “flash” is used on this website to refer to any device that produces a short burst of light (including flashes, speedlights, and strobes) and also to describe a brief burst of light.

Most normal flash photos are eligible to qualify as TTG (flash is a staple in news and reportage photography).

What flash photos are disqualified by TTG?

• If during the exposure there is movement in the scene and multiple flash bursts are used,

and/or

• if during the exposure the subject is illuminated by light sources coming from different angles at different times,

then the image will not meet P4 and would not qualify as TTG.
