I'd like to invest in some lighting for studio shots. I have plenty of camera equipment but no lighting, and worse, no knowledge of which brands are good for the money. I have 2 580exii's and nothing else. I'd like to get 2 stands, a soft box, an umbrella and 2 flashes (i think?) does anyone have any brands or sites to point in the right direction? or is there a standard "good" setup to get? any help is appreciated, even if its just some model numbers. my budget is around $400 or so.
