My light source is an Elinchrom D-Lite 4, 400J monoblock with a 52x52 cm softbox to modify the light. I placed the camera to the front of the statue pointing slightly downward and the light at about a 30 degree angle away to the left. I established the exposure using a handheld flash meter.
The first image is taken without the softbox mounted on the flash head and includes no post processing modifications:
Canon EOS 5D2, 50mm, f/9.5, 1/125s, ISO 100
I then attached the softbox and obtained the following image
Canon EOS 5D2, 50mm, f/3.5, 1/125s, ISO 100
One immediate difference was that I had to open the aperture out to f/3.5 to account for the light absorbed by the softbox. Otherwise the effect is very much as expected, the lighting is more even and the shadows far less pronounced, all in all a much softer image.
