Getting into the digital photography field. I will be purchasing a 20D shortly with a few assorted lenses. I'm not totally new to the field, however since I am on a short term budget I'm not sure what type of lighting I should go for. I will be doing mostly studio potrait or indoor type shots, it will mainly be portraiture either indoor or outdoor. At first I was looking at a rather cheap studio light setup, two heads, battery etc. However, I will be using another photographers studio for a bit and he has a pretty good setup already. So I figured I might just get a standard flash that can either be used on the hotshoe or used wireless through a pocket wizard. However it will lack the power of a studio setup, but I guess outdoors I would be looking to just fill light anyways right? If I do night shots would the standard (higher end) flash really be able to work? or should I do studio lighting. What should I start with? I think the strobe kit was like 1.3k vs a decent flash going for 400-500?
