Experiment. Don’t go out with preconceptions of what a picture will look like. That will block you from being receptive to something new and exciting. – Mason Resnick
What Mason said applies to all kinds of photography, including boudoir or intimate portraiture where it’s all too easy to pose a subject in “Pose A”, then move then into “Pose B,” making the whole process so mechanical that R2D2 could make this kind of portrait. But that’s not what your intimate portraiture clients want. They want a portrait of themselves that’s different from the last one you made and one that captures that subject’s individuality.
The same goes with your lighting. I once helped a friend who was sick for a few days and did sittings of his high school senior customers. Before filling in, the studio’s assistant showed me their lighting system that included strings with different knots representing different subject-to-light distances that were used to maintain a consistent lighting ratio but you don’t have to do it that way.
Sometime you can get by with just one soft box—no strings required. Using only a single Broncolor Litos head with 28-inch Broncolor soft box placed at camera left and aimed at the subject just as you see it at above right.
The light was placed at camera left out of camera range of the Canon EOS ID Mark IIN and (now sadly discontinued) EF 135mm f/2.8 SF lens used for the portrait. Exposure was 1/60 sec at f/10 and ISO 100. Lighting was metered with a Gossen Star F light meter and as always I typically shoot a few test shots to get one that produces the best exposure and histogram.
