Trying to figure out what I need for hair and background lights for my in home studio I am setting up. I have 2 alienbee B800's for main and fill lights but am totally lost about what to use for background and hair lighting for when I am doing potraits and such. I don't think I wanna spend 250 bucks on each of these two lights for something that contributes very little overall light to the image but yet is so important for good photographs (IMHO) What can a person use for this? I thought about using my SB600 on a stand but then I would have a wire running through my photo's from the camera to the background flash (sb600 canot be wirelessly tripped by the strobes from the alienbees) Thought about shop lights but I am concerned about the color difference between the shop lights and the alienbees throwing off the pictures. I saw a pic from a friend on deviantart and he sed the way he acheived the background color was through the use of a red gel on a background light with a black background. I want to be able to do things like that. Any suggestions?
