Demand for Power:
There is also the issue of batteries. Digital cameras use battery
power, and should the batteries deplete, the cameras will stop
functioning. Granted the digital cameras is more demanding on
batteries however if prepared, you can overcome the power demands of
the camera.
There are several options for power used by digital cameras.
Some cameras come with rechargeable batteries. Even those that don't
can be retrofitted with rechargeable batteries that are available as
an add-on purchase for almost all cameras. Since digital cameras are
quite power hungry appliances, rechargeable batteries are generally
considered to be the most economical way to go.
Some cameras come with proprietary rechargeable batteries that offer
convenience and often a long lasting lithium ion battery. Lithium
ion batteries, similar to camcorder batteries, have little memory
effect, which means that you can recharge the battery at anytime
without having to fully drain the battery.
They also offer a long lasting charge to maximize the use of your
camera between charges. The drawback to these systems is that,
despite the longer life of these batteries, they can be expensive to
replace and are specific to certain camera models. If you select a
camera with a proprietary rechargeable battery it is recommended
that you buy a spare to avoid losing power at an inconvenient time
(like in the middle of a vacation).
The other power option that digital cameras use is AA size
batteries. Due, however, to the previously mentioned power hungry
nature of digital cameras, standard AA size alkaline batteries, both
disposable and rechargeable, only last a few hours in the camera
with average use.
The best option for digital cameras is a high-output nickel
metal-hydrate rechargeable system
The advantage to these cameras is that in a pinch, if your
rechargeable runs out of juice, a AA battery can do the job until
you can get recharged.
Lithium disposable batteries also make excellent back-up power on
the road due to their long shelf life and reliability, so make sure
you carry a set to all your important events. Most cameras also have
capabilities for AC adapters. For convenience, why waste battery
power while you transfer your images to your computer or view your
images on the camera's LCD screen at home.
