I've been taking pictures for a few years now, but have never gotten serious about lighting. Now I want to start taking some snowboarding/skateboarding pictures, some portraits, and just improving my overall photography by learning and using artificial light. I don't have a huge amount of money to spend, but I really want to buy a decent lighting set. I don't want to buy some cheap equipment, and a couple months down the road when I'm getting into it, realize that I bought junk. Which pieces do I need to start? A pack and head, obviously. Also boxes, umbrellas, reflectors? What are some quality brands that are realistically priced? I really appreciate any help you can give a young photographer like me, even if all you have for me is a link. Thanks in advance!
