Latest pregnant pictures, tried to go for more pop than elegance this time, blue background for boy.
Setup: one flash on floor pointed up behind, one silver reflecting umbrella on stand camera right using flash with full CTO gel, WB set to tungsten to make grey back wall blue.
Two things I like about this right away - colour picture in full light and a nice smile.
I suggest you include some full profile shots to record the size changes she is going through.
I see some odd colours in the skin of #2 by her right hand. YOur back light is "escaping" on her right as well.
Using a 24mm lens may give you some distortion. None showing in #1, and not toobad in #2. It's something to watch out for, however.
