What
is it?
A digital camera
works much like a conventional camera with the major exception
being that it stores its photos digitally and stores them in
memory. Most cameras use removable memory that is reusable.
Why
would I want one?
Digital
cameras offer numerous benefits over conventional film cameras.
And, because they are more affordable then ever, they are popping
up in more households, on more family vacations, and in more
offices everywhere you go. Digital cameras offer countless
advantages for both personal users and professionals everywhere.
Cost-efficiency: A digital camera uses no film. Instead,
it stores its digital images on reusable memory cards or in
internal memory, and sometimes both. If you're a frequent
photographer, the cost savings on film and developing alone could
offset the purchase price of a digital camera in just months.
Memory cards are available in many sizes (in megabytes) and their
size and the image resolution combine to determine how many
pictures a card can hold. The great thing about memory cards is
that once you've downloaded the images to your computer for a
permanent record, you can erase the card and use it again. That's
like buying one roll of film and using it over and over again for
10 years or more!
Simplicity: Today's digital cameras are as easy to use
as the conventional point-and-shoot cameras you've been accustomed
to for years. In fact, most actually employ the simplicity of
point-and-shoot cameras without sacrificing on the features
necessary for quality images. And while just about any digital
camera is easy to use, the higher end cameras offer many advanced
features that are sure to satisfy the needs of enthusiasts and
professionals alike.
Versatility: Digital cameras are perfect for countless
uses, including professional, personal, or for just plain fun. And
you have even more options than film for sharing them with
friends, family, or colleagues. You can store all your images on
your computer's hard drive and/or back them up on tape, CD, or
floppy discs. You can share the back-ups with friends, family, and
colleagues. Or, you can email them, too. Imagine sharing pictures
of your newborn with grandparents, aunts, uncles, and anyone else
within minutes of his or her arrival into the world with just the
click of your send button!
How
do I install and use it?
The only
installation that is required of a digital camera is its
accompanying driver and image software. If you purchase a memory
card reader, additional driver software installation might be
required.
Because digital camera features vary, each one differs in its
capabilities and uses. Lower and mid-priced cameras are usually
fully automatic and as easy to use as a traditional film camera.
Higher priced cameras generally offer more bells and whistles and
can be more complicated to use.

How
do I go about buying one?
Choosing a digital camera is as easy as determining your need.
Consider first the camera's price and functionality and compare it
with other cameras. As a rule of thumb, the price of a digital
camera will generally reflect its capabilities. Simply put, higher
priced cameras offer more functionality and higher quality
pictures than lower priced ones. For a family camera or for casual
photography, most cameras in the $300 range should suffice. Keep
in mind, though, that you might sacrifice some very useful
options, such as removable memory card storage or an LCD viewer,
in lower priced cameras.
There are several key attributes you should pay close attention
to when considering your digital camera purchase. They include
resolution, memory capacity, viewfinder, flash, lens, focus, power
source, and interfaces (some cameras offer multiple interfaces).
Resolution: The higher the camera's resolution, the more
detailed the image is. Resolution is measured in pixels, which is
a single dot on an image. A resolution of 800 x 600 produces 800
pixels across the image and 600 pixels down the image. To
determine which resolution is best for you, determine how you
intend to publish your images. Lower resolutions, such as 640 x
480 are more than sufficient for publishing photos on the Internet
or viewing them on a computer screen. However, if you intend to
publish images in print, higher resolutions are necessary. Your
printer must also be capable of printing comparable resolutions.
It's recommended you consider a photo printer if you must produce
high quality prints of your images.
Memory Capacity: While some cameras have internal
memory, most of today's digital cameras employ a removable memory
card system, either SmartMedia, CompactFlash, PC Cards, or even
floppy discs. Essentially, they all serve the same purpose: store
images until you're ready to store them in a more permanent
environment, such as on a CD or your hard drive. The amount of
pictures a memory card can hold is dependent on two points: the
size of the card and resolution at which you captured the image.
High resolutions consume more memory. It's always wise to carry
additional memory as a back up in case you run out.
Viewfinder: Cameras offer two options for sizing up
pictures before you take them: an optical viewfinder and an LCD
viewer. Some cameras even have both. An optical viewfinder is just
like the glass viewer you've used in your film camera. You line up
your shot within the square in the glass and snap the shutter. But
probably the greatest advantage of an LCD viewer is that not only
can you size up your shot before you take it, you can review all
your stored images with it and delete any you don't want to keep.
You'll never be stuck with an blurry or over lit photo again.
Flash: While most digital cameras are equipped with a
built-in flash, not all come with one. Check the product
documentation carefully to ensure the camera has a built-in flash.
Also check to see if it fires automatically, which can eliminate
several retakes if you neglect to turn the flash on too often.
Red-eye reduction is also a great feature and you should check to
see if it's available.
Lens: More cameras are offering zoom lenses today that
allow you to change the lens setting from normal to wide-angle to
telephoto. A zoom lens is an excellent feature and useful to any
photographer.
Focus: Many of the less expensive cameras feature a
fixed focus, meaning the camera is set to shoot from a specific
distance. Many higher end cameras include an auto-focus that does
all the work for you.
Power Source: Most digital cameras are powered with an
AC adapter, batteries, or both. Having both is your best option.
Downloading images and using the LCD viewer drain battery power
quickly. The added convenience of an AC adapter, especially for
downloading the images to your computer, ensures your battery
power is saved for when you need it to take pictures.
Interface: A camera needs to interface with your
computer in order to download the images from either its internal
memory or its memory cards. Most cameras use a serial interface,
which is standard on most all computers. Unfortunately, serial
interfaces are slow. If your camera uses memory cards, you can
purchase a memory card reader for faster downloads and to save the
hassle of connecting, disconnecting, and reconnecting a cable from
the camera to your computer each time you download images from the
camera. Newer models are using a USB interface, which is faster
than a serial interface. And some cameras offer a PCMCIA interface
for connecting to your portable computer.
TV-out: This feature is essential if you want to share
photos with someone who doesn't have a computer. The TV-out
connection allows you connect the camera directly to a television
set with a cable so you can view them on the TV screen. You can
also use this feature to connect it to a VCR and record your still
images on to videotape.
