Here is the set up for the orchid image. I used natural light coming in from window left. Then I diffused the lighting using three 24x36 china silk scrims that you can see in the picture. The silks come in different thicknesses, full, 1/2, and 1/3. I used two full and a 1/3 third. This way I can feather the light and give different areas of the image a controlled value.
You can see in the picture that the window light at some point is going through all three silks making a 2 and 1/3 stop of diffusion and in the middle just two silks. At the top, only one silk is diffusing the light.
On the right is a piece of white foamcore and what you can't see if a strip of Roscoflex silver reflector material running down the middle to push one slice of light toward the orchid.
There is also a 12x18 Lowell silver reflector on the floor pushing bounced light toward the wall.
Again, it looks like a simple shot but with diligent light control I can spread the light the way I want and produce an overall light palette.
