I did my first maternity shoot yesterday afternoon. One of the reasons I wanted to do this shoot was that the client wanted to have a "milk bath" scene in the shoot and having seen Annie Leibovitz's famous shot of Whoopi Goldberg, I was intrigued enough to want to try one.
1. High key look - natural light only
2. Milk bath - one bounced studio flash
By the way, we weren't using milk. The "milk" was a combination of commercial coffee whitener (Coffeemate brand), corn starch and baking soda. This provided a mix that was translucent for the top 1 - 2 cm / 1/2 - 1" before becoming quite opaque. Unless one is careful, the corn starch can be a bit lumpy; which is not desirable... The flower are "real" flowers, rather than silk or plastic ones. Real ones float, the artificial ones don't.
