I have three flash units. One is an Interfit 300w/s monolight. The other two are speedlights: Nikon SB-910 and Yongnuo YN560iii (about $75), just got the 560 this week. I have been practicing on taking 2-light setups with speedlights. I want to learn it because it is so much easier than carrying a monolight and battery pack around. I took this of my cat. The main is camera right, and the fill is left. This is with a 16* grid on the main and a snoot on the fill.
