Here's how to gain more time behind the camera.  Plan your setups (up to 6 different lights per setup for the subject and 2 lights for the background) before going to the studio. The time that you used to spend moving lights back and forth as you take endless flash meter readings, can now be time spent behind the camera - honing your creative skills by actually shooting photos. This is possible because Studio Flash Wizard^® Light-ratio software tells you exactly how far from the subject to place each light to produce the light-ratios you choose!  And Color Background Flash Wizard tells you exactly how far from the background to place your lights to duplicate the exact color and shade you have selected.  Yes, that's right - you no longer have to take repeated flash meter readings in the studio and constantly refer to tables to get the light-ratios you want.  And you no longer have to change the roll of background paper every time you want a different color.  Use the same roll of black background paper for all your colors and shades.  If you know the approximate size of the school's studio you can plan all  your setups before going to the studio!
