I took some Christmas portraits of our girls this weekend. These were not done in a studio, just our living room. I put up a background stand and a black material at one end of the room. Then the kids were placed forward of the background 6 to 8 feet. This was done to keep the spill from the lights off the background.
The lights were one or two shoot through umbrellas. The main light was on the left and closer. The fill was on the right, a little farther away, and two stops lower. These were SB900′s as remotes. They were triggered by the on camera flash that contributed nothing to the exposure.
The trick here is getting the kids away from the background, and feathering the light to that most of the light goes across the girls creating interesting shadow, and keeping the light off the kids.
This can be pulled off in any home with enough space to get the kids off the background. With less space you will see the pattern or wrinkles in the background. If you would like pictures like these of your kids, please contact me.
