Caleb Pike of DSLR Video Shooter shares an easy, inexpensive way to make your gear bags easier to unzip, as well as locate when you're not in well-lit areas (like...behind the scenes on a dark movie set). And all you'll need is a length of cheap paracord.
This might not seem like a particularly substantial filmmaking tutorial, but if you think about how often you fumble around with your camera bag, or how much time you spend trying to locate it amongst the other almost identical bags lying around (if you have a lot of gear), then this solution is a lifesaver. Honestly, after watching this I thought, "Ah! Why didn't I think of that?"
Pick up some colorful nylon cord, scissors, and a lighter and make mishandling gear bag zippers a thing of the past.
