After some advice on softening directwhile outdoors. I've been playing around with using my 580EX + PW off camera to provide some fill on some of my climbing photography but the it a little too harsh. I normally bounce when indoors but obviously there isn't a white ceiling outside
If it was indoors I'd just go for an umbrella but I can just imagine a gust of wind carrying away my flash and stand with an umbrella outside, so something a little more compact / wind friendly would be good. Oh and lugging a sand bag to the a climbing location to hold the stand isn't going to happen so no one suggest that
Any suggestions? OmniBounce? Small softbox attachment?
