I'm interested in shooting some video and would like to know what l need. I currently have a canon g16 with a Fantasea housing, macro and wide angle lenses and two ys-D1 strobes. I also have a GoPro 3. What video lights would you recommend ? Do I need two or will one do? Blue water has the I-torch venom 38 on sale. Any thoughts. I'd like to get the most for my money. Thanks!
