Ya know how I keep my equipment dry when it's raining out, I stay indoors. LOL. Seriously, that's really what I do, other then the time this photo was taken, I was co-teaching a workshop with Jack Graham and it was raining and we had to power on through the rain to keep the clients shooting.  What I found is the cheapest and easiest way to keep the camera dry, is to just use a garbage bag over the camera until it's time to shoot and then just lift up the bag over the lens hood and the cameras view finder, line up shot and shoot. Move the bag back down after the shot.
