Perhaps it won’t save the planet from global warming, but it’s useful to know which of your digital camera’s functions use the most battery power. Below are four of our best camera tips for extending your camera’s battery life. Try following these energy-saving options and see if you notice a difference as to the number of pictures that you can shoot between charges.
1 Review off
An obvious way to save energy is to not use the built-in flash and Live View (find out: what is Live View telling you?), focus manually rather than use AF (for more, see our in-depth guide to Manual Focus: what you need to know to get sharp images).
But a great way of saving juice is to turn off the image review, so you don’t see the shot on the LCD after you take it. Try shooting without it for an afternoon. Not seeing your images immediately will feel strange, but this lack of visual feedback is what everyone had to put up with in the days of film!
2 Auto power off
Another useful trick is to turn the Auto Power Off menu option to the minimum amount allowed – that way your camera will go into energy saving mode for you. It will switch everything back on as soon as you half-press the shutter release button.
3 Turn off the Beep
Some energy-saving measures won’t save much juice, but are worth using when they are not needed. You may as well turn off Image Stabilization, for instance, if you are using a tripod (find out how to use a tripod the right way). And the world will be a quieter place if you turn off the annoying focus-confirmation beep in the main menu – also useful for quiet candid shots.
4 Bad ideas
Be careful about some energy-saving ideas. You can save power by reducing the brightness of your LCD, but then your pictures may look underexposed when they are not. You can save power by not shooting in RAW, reducing resolution, and by avoiding long shutter speeds – but all these things may well negatively effect your photographs!
