Despite the best preparation, sometimes you find yourself dangerously low on battery life with a full day's activities ahead of you. Get those last shots with these battery-conserving tips.
It happens to the best of us. You glance at your camera before heading out and it looks like you've still got a decent amount of battery life. A few hours later you're staring at one bar and wondering how long you've got before you're out of luck. Digital Photography School has put together a guide to milking the last bit of juice out of your camera battery. The tips are all practical and apply to most cameras. One sure fire way to extend battery life, for example, is to crank up the ISO:
Your flash can kill your batteries in no time flat. Depending on your camera's capabilities, it may be a worthwhile option to increase the ISO a bit in marginal lighting situations to lessen the use of the built-in flash. Before your trip, or right now, do a few quick tests in moderate indoor lighting (the most likely scenario for flash use) to see just how far you can push the ISO before it doesn't look good to you. This setting is purely subjective. If you can stand the grain at ISO400 on your camera, then go with it. Some cameras look horrid above ISO200. Don't take someone else's, or some website's, word for it, try it out yourself and see what looks good to you. Flash use has been shown to reduce battery life by as much as 40%.
Not sure you want to mess around with the ISO settings? Even little things like turning off the image review will give you longer battery life.
