Hi there! I'll be embarking on a 3-week backpacking trip later this summer on the John Muir Trail in California, and I'll be bringing my camera gear with me. I only have one spare battery, and while I know that isn't enough for 3 weeks, I'm not sure how many more to get. There's a chance I'll get to recharge them while on the trail at one or two of the resupply points, but there is no guarantee. Does anyone have any experience with these kinds of long trips without ability to recharge? And if so, how many batteries did you bring/use? I've considered picking up a Brunton SolarRoll which would allow me to recharge along the way, but I don't really have the room in the wallet or the pack for one of these things.
Some extra info:
-I'll be taking approximately 130 shots per day (due to memory limitations)
-I'll be shooting at dawn and dusk only (cold weather drains batteries quicker?)
Any advice or tips on this subject would be great. Thanks!
