During the recent San Diego, Nikonian's workshop, I demonstrated a wonderful feature of the popular FourSquare™. The hub of the system is the Square block that the 4 flashes attach to. One of the features of this block is that it has two umbrella shift holes to hold two umbrellas. Why two? Super Soft Light!
In the set-up shown above, I have one strobe on the FourSquare™ pointed into the 43" convertible umbrella that bounces the light back into a 60" shoot through umbrella. This is a very soft and wrapping light that I just love.
Here is a sample image of our model Amira from MM.
