Pay Only for the Digital Camera Features You Need

Before shopping for a digital camera, be sure you know
enough about the key features so you buy only what you need
Although friends, family members and reviews are good
sources of information to consider before shopping, here
are the basics to start with.
Because the term megapixel relates directly to image
quality, you will see it mentioned prominently in any
digital camera advertising. Dots called pixels make up a
digital image. with a megapixel equalling one million
pixels. Typical consumer cameras range between two and five
megapixels.
The more megapixels the sharper the image, generally, but
the size of enlargement is the important issue. You will be
okay with three megapixels for enlargements up to an 8x10,
but for larger photos you'll want more. If you plan to go
big, the extra expense for a five megapixel is worth it.
But save your money if you will use the photos for emailing
friends or to make small enlargements.
The next consideration is the lens. Cheaper models
typically have fixed lenses, which means you can't zoom in
or out. What you see is what you get, no matter how far
away you are from the subject. That's why zoom lenses are
worth the extra cost unless you're happy with very basic
photos. A 3x zoom is a good compromise for general
photography, though if you're thinkng of taking wildlife
shots a 10x will be much more useful. It's important to get
an optical zoom instead of a digital zoom, which simple
enlarges the pixels and therefor harms picture quality.
Of course, if you want even greater flexibility, with
professional cameras you'll have interchangeable lenses.
With the hefty expense comes much more potential for great
photos.
How you will use your digital camera is another
consideration. Both video and still pictures can be made
with some models, although with the less costly cameras the
video will be quite short -- 30 seconds or less. For more
money, a combination model gives more video time.
Size is a key factor. Will you want to carry around the
camera if it is large? Or will you make better use of a
compact model that fits easily into a pocket? While image
quality is typically better in the larger models, the
smaller cameras do very well and likely get more use.
To store images, practically all digital models use a
memory stick or card. And most come with a small amount of
memory that holds few images. So you will need to make an
additional purchase of memory that holds 50-100 images. So
be sure you can buy extra memory for your model at a
reasonable price.
Intensive battery use is common for digital cameras,
particulary when the LED screen is on. Some of the big name
brands use a proprietary battery that's costly to replace.
Best is a battery that's easily available and a snap to
recharge.
Software to download images onto your computer will come
with the camera, making editing and emailing them an easy
affair.
Additional software like Photoshop would be needed for
serious manipulation or for more professional projects.
Check on the software compatibility with your computer
before buying.
