Memory - How Does
Memory Work?
A digital camera uses memory to store the digital code that make up
the images. The more memory you have available, the more pictures
you can store.
There are very few cameras on the market that offer built-in memory
because it is generally quite limited. Instead, most cameras today
include a type of removable memory to store images called a memory
card. Think of the memory card as a re-usable digital film. The size
of the memory card determines the capacity of the camera to store
pictures.
The resolution of the camera also influences the amount of memory
required. The higher the resolution of the camera the larger the
file size of the image. Most high-resolution cameras can take
pictures at a lower resolution setting, allowing you to fit more
images onto your memory card.
Memory cards are reusable. In order to keep the images you must
transfer them to another form of media to free up the camera's
memory card. A popular option is to transfer them to CD-ROM, which
is an inexpensive and reliable form of removable media. If a CD
burner is not available to you, CD-ROM transfer service is available
through your London Drugs Photofinishers.
There are many different types of memory as well, including Compact
Flash, Secure Digital, Memory Stick, and XD. These various shapes
and sizes operate in a similar fashion, and the type of memory card
you use is generally dictated by the type of camera you select.
While one memory card is not necessarily better than another, these
types of memory are beginning to appear in many other electronic
devices so it may be in your best interest to keep things
compatible.
An idea to consider is the purchase of an additional memory card, an
extra one to use as backup. Here again, more is better; and the more
memory you have available, the greater the number of pictures you
can store on your memory card before it is full and needs to be
downloaded to your computer or transferred onto CD ROM and made into
prints by a photolab.
The ability to store a large number of images without having to
download is especially useful if you are away on vacation.
You are traveling to Africa and want to photograph your vacation.
While on your air balloon ride your memory card fills up. Your
choices are; delete images and continue to shoot, use your
additional media you brought along, or if already filled up,
purchase additional media in the country you visited.
If you prepared in advance you could have previously purchased a
digital wallet. This allows you to download your images into a 5, 10
or 20 gig portable hard drive which fits conveniently on your belt,
then delete the images on the card and continue to photograph.
While purchasing additional memory cards can be expensive, they are
a worthwhile investment because they can be used over and over
again.
