My wife and I moved to central Florida about a year plus ago and I've been trying to figure out some reasonable ways to defend against heat and related issues while shooting and carrying film. I've started carrying a small soft lunch size cooler for carrying film when I'm out and about but have been curious what other people who have been in this lovely state longer than I, have figured out for controlling heat, humidity, lens and film fogging, etc. while the loaded camera is in use or being carried in a camera bag with lenses and the like. I've tried carrying small commercially available frozen blue ice sleeves at the bottom of my camera bag covered with towels to absorb the moisture while keeping the camera and lenses relatively cool and dry but they take up too much space and I'm worried about mold, mildew and fungus growing on my bag and gear. I've started carrying a medium size Coleman cloth cooler as a makeshift camera bag; it has a plastic basket that can be removed so you can put those thin blue ice sleeves at the bottom, under the plastic basket, but the exterior cloth still gets wet and I get condensation at the bottom of the basket. What do y'all use to enjoy photography in our balmy state!?!
