Have you ever wondered how to wisely select the digital camera that
matches your needs and expectations? Choosing which digital camera to
buy may be very complicated and irritating because there are too many
technical factors and elements involved in the process. Moreover, having
a lack of technical background or experience with technology can cause
more confusion. There are three fundamental factors that any digital
camera consumer should take a careful look at before buying: the type of
a digital camera, megapixels, and memory capacity.
The purpose of
your digital camera is the single most important part of your
selection. In other words, what is the camera going to be used for? Are
you going to use it to make professional pictures like a paparazzi? or
maybe you just want to use it take picture for yourself and your family
when you go out. In short, there are two basic categories of digital
cameras: professional and personal/family digital cameras. The
professional ones tend to have higher picture quality and more
functions; however, at the same time, they are significantly more
expensive than the personal/family ones. The price of a family digital
camera can range from $50 up to $400 and $500 but the professional ones
can cost from $400 up to a few thousand dollars. So, before you buy one,
know what you are going to use it for.
There is a very high
correlation between the number of pixels in an image and the overall
quality of the image. Pixel is the smallest unit of a picture that can
be controlled or represented. Digital cameras are usually measured in
megapixels, which is referred as one million pixels in an image. The
higher the number of pixels in the picture, the higher the quality of
the image tends to be. For example, if one camera has 5 megapixels and
the other one has 10 megapixels, the quality of the image taken by the
10 megapixel camera will be significantly higher most of the time.
It
is very important that you do not forget to find out the memory
capacity because you certainly do not want to miss that one
unforgettable picture because your camera's memory is full. The memory
of a camera is measured in megabytes or gigabytes. 1 megabyte is equal
to 1 million bytes and 1 gigabyte is equal to 1 billion bytes. Always
remember, the higher the amount of memory in a camera, the more picture
you can take and store. Internal memory and external memory are the two
memory categories of a camera. Internal memory is the on-board memory
the camera has in its internal hard drive and the external memory is the
external hard drive of a camera, which is usually a removable memory
chip. In order to figure out the memory capacity of a digital camera,
pay attention to the maximum internal memory the camera has (this memory
cannot be increased or decreased) and also the maximum memory chip the
camera can take (cameras are limited to the amount of external memory
they can take).
