The setup is pretty simple....
I mounted a canon 580 EX II on a tripod, and raise it hight enough to the ceiling...
This was a small baby and the poses where simple...always on a hug or on the sofa..so the light would come from the top and fill with soft light this little angel.....
Here is the setup shot...
simple..true simple.....
I used a Canon EOS 5D with ST-E2 transmitter for triggering the 580.
The ISO was set to 400 since i had only one light.
A canon EF 70-200 F:2.8 was used
The white balance was set to Auto..and it worked pretty well..
The 580 was in manual mode at 1/16 of power (Maxa Powerex batteries where used)
F:7,1 t:1/40...pretty risky if you thing that this angel couldn't stand still..
I chose RAW file and shot about 250 frames.
