OK, I decided to try out my home setup on my own family (me included) and would like to know where I can improve. More of this series to come...
I wanted the rembrandt effect and used a 540FGZ flash off a reflective umbrella above and to the left of the camera with the pop up flash as the front-on fill flash and wireless trigger.
Shot with K10D and FA 50/1.4 at f/4.5
C&C welcome. I noticed that one of the girls is OOF in one of the shots - I think I'm going to have to stop down a little more next time. But comments on ways to improve are most welcome.
