If you use my snap together picture frames you can build a diffuser/cucoloris to be used with your speed lights while on location. Here is a wooden frame that I leave in the studio and use plastic cardboard to build sides to the frame. I then place a speed light on a stand and power it through this set up. I can get different background effects just by how the head is rotated and how close or far away the head is from the LightBreak pattern. Remember that the zoom level will also change the look. Go ahead … experiment!
