With the advent of digital photography, we are no longer shackled by the ’36 exposure’ limit which plagued the film. However with digital though one is bound by another limit, that of a battery. If the battery of your camera discharges completely you can’t do much than stop shooting. And this has the canny ability of happening at the most unfortunate of moment. So in order you do not lose the shot, be prepared. Take serious heed of the things I put forth & you’ll never run out of battery charge.
# Limit LCD Usage : On every digital camera, the LCD monitor at the back is the sole reason why the battery drains quickly. Every-time you review pictures on the monitor or use it for some another reason, the battery levels begin to tumble quickly. So I recommend, you use the LCD monitor sparingly. Implement the following, so the LCD monitor doesn’t eats up much of the battery.
Monitor Off – Some camera’s have a time setting which enables the user turn off the LCD display. In Canon, the user can turn off the display by pressing the ‘DISP’ button for a couple(on some thrice) of times. Check your camera’s manual to find this.
Limit Live View – Live view can be really useful at times however using it at times when you could have used the optical viewfinder will seriously consume your battery. Its incredible, that when one does not use the live view during shooting, the number of shots one can take increase almost threefolds.
Display Brightness – The brighter the display, the more battery power it will consume. Set the display to its lowest power & turn off auto brightness option. Only increase the display brightness in case it is crucial to absolutely crucial to check the LCD display.
# Use Auto-Focus only if needed : Auto-Focus(AF) too requires a great deal of power to function. In low light, the focus hunting will mean draining more of the battery power. Also I have noticed, some people have the habit of engaging the AF needlessly. Change this habit. Use AF only if you’re shooting at wider apertures when the battery level is low. Using a narrow aperture & manually focusing the lens will save a great deal of battery power & allow you more shots.
# Disable Image Stabilization : The ‘Image Stabilization’ on your lens too eats up the battery. When shooting with a tripod, disable the Image Stabilization. By maintaining the reciprocal rule of shutter-speed & proper hand holding techniques, you can get sharp photographs even without ‘Image Stabilization’.
# Avoid Popup Flash : If your camera has an inbuilt popup flash, avoid using it. If need be, use an external flashgun. The inbuilt popup flash is another battery killer & will end up your battery in no time if you keep firing it frequently.
# Buy a Battery Grip : A battery grip contains two of your normal camera batteries. Attaching a battery grip to your camera will instantly double the number of photographs you can shoot. Additionally, it also provides good ergonomics & comfortable portrait shooting when plugged into the camera. Its advisable you get original battery grip from your camera’s manufacturer for your camera model & put original batteries in it.
# Turn Off : Generally if you’re shooting photographs with not much of delay, it is better to keep the camera on than to switch it off. Switching the camera on-off does takes a bit more battery power than leaving it on. However, if you plan to shoot later then its advisable to switch it off. Its the best way you can conserve your battery. Even if you’ve set the “Power Off” option for your camera after certain delay, it is more effective to completely switch off the camera from the power switch.
