Top tip: buy a second battery (and keep it charged!) · Sep 11, 11:16 PM by Simon Mackie
Modern digital SLRs are great, but one disadvantage is that you are totally reliant on the battery – on older manual film SLRs even if the battery failed and the meter wasn’t working, you could still take pictures by using the sunny-16 rule, making a best guess for the exposure, and bracketing. However, on a DSLR, if the battery goes,you’re stuck with no ability to take pictures at all. Avoid what happened to me at the weekend – buy a second battery, keep it charged, and keep it in your camera bag at all times. Otherwise, you’re guaranteed that the battery will fail just when that perfect photo appears.
