Hi everyone. I've been wanting to do some portrait shoots and have bought several things. All I've done is shoot outside shots. I'm new to portrait studio shooting. I've bought the following lighting: Smith Victor KT750U 3-Light 750-Watt Thrifty Photoflood Kit with Umbrella http://www.adorama.com/SVKT750U.html Smith Victor FL160 110i 1-Light Kit W/ Softbox http://www.ritzcamera.com/product/EP4462123.htm and a rack with a white paper roll Am I able to add more watts to the photoflood kit and the softbox light? Can't seem to find anything on adding more watts to it. So far I'm using about 810 Watts..What is the minimum recommendation for a small studio? Anything else I should consider getting?
