(A few examples : Prom/Event at The Rock Inn, Halifax.)
For this shoot I provided a black back drop and two lights.
to get this look.
A light meter can be used to gain the perfect settings. I use my technical knowledge and adjust the ISO , shutter speed and F stop first of all as a test, using my assistant - then I am up and ready to go!
(The back drop is a nice additional package to have at a party for a different kind of look.)
