I have a brand new photo studio and I would like to know how I should set it up. I do not have a fill card but I have two lights with umbrellas and then a third with just the light to use as a back ground light. Where in accordance to the model should I place my lights and at what height should they be in accordance to the model? I was also wondering how far or close to the modle should I place my lights? I have 35 watt daylight bulbs 5500K. Thanks for any insight someone can provide on how to do this.
