hey I'm tying to get into fashion photography and stuff. I'm wondering what kind of lighting I should buy. I'm new to lighting so I'm a beginner with it all. So far all I own is a SB-600 flash. Should I buy an umbrella or softbox or something else? I want to be able to do some dramatic lighting and stuff. Something not too expensive. I don't know where to start. Or any link to some good site with info about what equipment is best for what and such. I plan on using the lighting in an outside environment at different hours of the day not in a studio.
