Digital cameras
Digital camera picture quality is increasingly on par with the quality of most
conventional film cameras, while convenience and the ability to record, edit and email
photos on a computer are making them more popular. They are as simple to use as
traditional point-and-shoots but have added features such as exposure adjustment, special
effects, and clear, bright LCD screens that let you preview your pictures before you take
them. Improvements in digital storage allow you to take up to 120 pictures on certain
memory cards. In addition, you never have to pay for film processing, and you get
your photos immediately, instead of having to wait for the prints to be developed. You can
e-mail photos to friends, print them out on photo paper or stickers, or post them on the
Web, all without hassling with photo labs or scanners.
Digital Cameras make taking and sharing snapshots more fun, more convenient and just about
foolproof. They're as easy to use as standard 35mm cameras, but the technology built
into digital cameras converts the snapshots you take into a full-color digital format that
can be previewed on the spot and downloaded to a computer for even more fun.
There's no film involved. Use your computer to change the look of the photos and include
them in e-mails, business presentations and brochures - or print them out to show family
and friends.
Today's models offer many of the same features found on good 35mm cameras: flash, red-eye
reduction, autofocus, zoom and self-timers. Plus, they offer conveniences you'd never find
in traditional cameras, such as built-in LCD screens that allow shots to be previewed
seconds after snapping them.
Basic features
Resolution: Probably the most important
feature to consider in your camera purchase. Resolution is represented in two ways; either
as pixels in millions (megapixels), or as the number of pixels displayed as Width x
Height, as in 1600 x 1200 pixels. If you're only a casual photographer, and you just want
to take some occasional pictures to print out in small sizes, load up to the web, or email
to friends or family, then a lower resolution (around 1152 x 864, or 1 megapixel) will
probably fulfill your needs. If you plan on making photos of different sizes, or want to
get a little creative with close-ups or color, you'll want to work with a more mid-range
resolution, somewhere between 1152 x 864 (1 megapixel) and 1600 x 1200 (2.1 megapixels).
If you're very serious about your photography, look for a model with 3 megapixels or more
(at or above 2048 x 1536).
Memory: Most cameras come with a relatively small amount, but you can purchase
additional cards to give you more memory and, therefore, the ability to take more pictures
without needing to go back to your computer to download. Some cameras utilize other forms
of digital camera "film," including floppy disks, Memory Stick, internal memory
chips, and even compact discs. Be sure to pay attention to what format you'll be using.
Most cameras will come with enough memory for you to take roughly the equivalent of a roll
of film, depending on the resolution you use.
LCD Screen: Allows you to see how a picture will look before you take it, and even
view the picture you just took. Many LCDs also allow you to view all the pictures you've
taken so far, sometimes even all at once. This is a very handy feature considering you
only have so much room in your camera's memory, so getting rid of poor/unwanted photos
frees up more room.
Lens: Be careful when shopping around. Some cheaper cameras have great resolution,
but feature lower quality lenses that sacrifice image quality. An optical zoom lens is a
nice feature for digital photography, but don't confuse that with a digital zoom, which
closely simulates a traditional zoom, but loses some resolution in the process.
