I am going to purchase some lights...but I'm not exactly sure where to place them. I hear so much about soft boxes...but I just don't know what is good and how much to spend. I'm sure I can spend a lot...but if there is someone out there that can tell me which brand to buy...I know expense doesn't nessarily mean good...I'm sure I can buy cheaper ones out there that would work just as good. I've seen some here show graphs as to where to place your lights...if someone can show me that as well...I would be most grateful. I know I'm asking a lot...but I also know there are lots of talented photographers here. Lighting is such a big part of taking good pictures...and I just want to get better with lighting. Thanks in advance.
