I'm just getting back into photography and I'mbuildinga potable lighting kit to shoot portraits of bands while I am on the road. If you have ever seen "confessions of a professional photographer" on you tube, I am trying to emulate his set up. I'd like to have 2 remote flash units for lighting, so my question is... Should I buy high end canon flashes or can I get away with sigmas? And... what is the best way to wirelessly trigger my flashes, is there an alternative to pocket wizards? Being a musician/photographer means I'm on a seriously tight budget. I have done tons ofresearchon the internet, just looking for some human feedback and suggestions! Thanks!
