Find the Best Digital Camera for

Digital Cameras have become a common site wherever you go.
If you're getting ready to purchase your first digital camera,
or maybe you're looking to replace one you already have, it
is best to familiarize yourself with the knowledge of what makes
one digital camera different from another and choose the one
that is right for you. In this article we'll cover one of the
most significant factors in picture quality. This is the “digital
film.”
Just like with a film camera, the digital camera has a lens
which brings light into focus on a bed of light sensitive material.
In the digital camera, that light sensitive material is a circuit
bed called a “CCD.” The CCD plays the same role as film in a
film camera and the lens allows light to fall onto the CCD which
is then converted into a digital image. The quality of the lens
can make a significant difference in the clarity of that image.
Very cheap digital cameras may even use a piece of plastic as
the lens, which will usually have an uneven surface and light
transmission. This will be noticeable in the picture but may
not be an issue for a security camera or a web cam. Better quality
digital cameras will have ground-glass lens and high-end digital
cameras will even have interchangeable lenses as do high-end
film cameras. The lens still plays the important role of bringing
light clearly to the CCD surface for a distortion free picture.
A CCD also provides an interesting advantage to the digital
camera. It is possible to automatically adjust light sensitivity
to improve contrast, shoot in dim light, or even take black
and white, sepia or infrared and ultraviolet light pictures
with the touch of a button. Because any of these images are
stored as the same data on the memory card, a digital camera
can offer unsurpassed versatility without the need to change
film types. Not all digital cameras have these features built
in, but they are options you may see in some cameras. While
the possibilities are cool, ask yourself if you that is a feature
you need in a digital camera.
With digital cameras, CCD is a grid of light sensitive points
which capture the image for conversion into a digital image.
The number of points on the CCD is measured in terms of “mega
pixels.” The mega pixel rating is a completely new bit of terminology
and is unique to the digital camera. The mega pixel rating is
a measure of the resolution of the camera, or its ability to
store details of am image. For example, a digital camera with
a maximum resolution of 1280 by 768 pixels (dots) comes out
to a total of 983,040 pixels with which to describe the digital
image. As each mega pixel represents one million pixels, we
can see this isn't even one mega pixel. Some digital cameras
have mega pixel ratings at 5.1 and even 7.1 mega pixels. What
does this mean to you? The more pixels the more detail stored.
If the image is going to be viewed on a screen or a TV, this
isn't very meaningful because video displays have resolutions
which are usually well below one mega pixel. However, when printing
on a high quality photo printer, the difference between a 3
mega pixel digital camera and a 5 mega pixel digital camera
can be very obvious.
Some people will try to evaluate a mega pixel rating by how
large a print can be made from the digital camera's image. The
truth is that any digital image can be printed to any size.
The real issue is what it looks like. Most people print their
film to 4x6 prints and many are now doing the same with their
digital cameras. Ask to see printed samples of pictures which
are like the type you would normally take and compare the same
prints between different cameras. Many stores will try to dazzle
you with colorful still life images of piles of multi-colored
fruits and hot air balloons. Do you take pictures like that?
Probably not, so perhaps they're not the best images to be scrutinizing.
If you take pictures of friends standing around, use each camera
to take pictures of people standing around. Then use a demonstration
printer at the store to make prints and look at the results.
Do you see little dots in the middle of solid colors? Does the
image look like it was taken with a poor quality film camera?
Don't seek out the digital camera that happens to take perfect
pictures in a perfect setting, contrived by the marketing department
of the digital camera's manufacturer. Look for the digital camera
that takes pictures you like in the settings in which you most
commonly find yourself.
Another issue to consider is that some digital cameras are
designed for “point and click” use while other cameras are designed
with lots of settings which must be manipulated for optimal
results. In my personal experience, I have found that Kodak
makes digital cameras which are ideally suited for simple “point
and click” use and consistently take great looking pictures
in a wide variety of settings. I have also personally found
that digital cameras from Nikon work best when you set them
to “manual” and do not rely on the automatic settings. This
seems to be true of their film cameras as well. Does this make
one digital camera better than another? Only if one fits your
needs and skills, and the other does not.
There are many magazines available on digital cameras today.
Most recognize these differences in digital camera quality,
based on needs and intended use of the owner. Before buying
your new digital camera, pick up a few of these magazines and
familiarize yourself with the latest reviews. Remember that
the pros and cons are still written “through the lens” of the
reviewer. If you see a negative about a digital camera that
you otherwise like, ask yourself if that negative is meaningful
to your needs. Next ask yourself if that negative might be meaningful
to your needs as you become more experienced. If the answer
is yes, ask yourself if you would still be using that camera
as a more experienced photographer in the future or would you
perhaps sell it and buy an entirely new digital camera? It's
unlikely that the digital camera you buy today is going to be
the only one you'll ever have. Buy the digital camera that most
reasonably meets your needs and how you normally plan to take
pictures.
Memory cards and battery life are also consideration factors
which will be covered in other articles. For now, I hope this
information has taught you more about the workings of a digital
camera and some of the factors to consider when choosing one.
Take your time and learn a bit about digital cameras before
your purchase. Sure, it's not like buying a car, but photography
is a very personal experience and the right digital camera will
truly make a difference in your enjoyment of capturing the moment
with digital photography.
