So first thing in the larger bag is my YongNuo Wireless Trigger / Remote set. I talked about them in this article: http://cheesycam.com/never-ending-upgrades-wireless-shutter-flash-remotes/. As you know i've been building up a studio and these versatile triggers can wear many different hats around the equipment i'm using. First off, I can now use my Canon 580 EX II's through the hotshoe these remotes provide, or trigger my studio strobes through a PC sync cord these offer, and if I really needed to, trigger my camera shutter. OK that's a bit overkill to remotely trigger my camera in studio, but I really was just looking to replace some old Pocket Wizards since these will allow me to expand to more triggers at very minimal cost. For times when I don't want to travel with my ST-E2 or Radio Popper PX's, these will work great. I'll do some closeup detailed photos possibly tonight or this weekend and explain why I currently use so many different trigger sets.
