Creative lighting is all about what you do not light:
I used one bounced flash and a prime 35mm lens on a full-frame body.
The camera was on manual of course, and shutter, aperture, and ISO were set to make sure the background was dark, but with colour showing in the background.
Flash was on TTL.
I wanted to emphasise the girl’s striking eyes and hide her face, and emphasise her look, so I bounced off a black ceiling above her. Yes, even a black ceiling will reflect some light! And 1600 ISO and the lens wide open ensured that “some” light was “enough” light.
Not your typical party picture – precisely because I did not light all of the girl.
