Digital cameras are revolutionizing the world of home and
professional photography, but they are married to memory cards just
as traditional cameras are married to film. Making the best use of
memory cards can have a very big impact on your enjoyment of
digital photography. Choosing the right memory card for the job can
be as important as choosing the right film for a traditional camera.
If you are new to digital cameras, the digital camera memory cards
are the most important parts of any digital camera, without which they
may not work at all. So if you are handling a digital camera or
planning a purchase, you must know more about the memory cards
used in these cameras.
Something many new digital camera owners find counter-intuitive is
that bigger is not always better with a digital memory card. The actual
response speed of your digital camera can depend greatly on the
memory card it is using. The speed that your camera writes new
pictures to the digital memory card is partially dependant on the
transfer speed of the digital camera but is also dependant on factors
in the memory card itself. Memory cards that have ˇ°buffersˇ± can take
the data into a faster type of memory and then transfer the data from
there to the slower ˇ°flash memoryˇ± which provides the main storage of
almost all digital camera memory cards. Some digital camera provide
their own buffer memory to allow you to take your next picture while
the previous picture is being transferred to the memory card.
When you delete an image from the memory card of your digital
camera, the flash memory is ˇ°reconfiguredˇ± because of special issues
having to do with how this memory stores data. Normally this is an
issue that you don't have to worry about at all. However, if you have a
very large memory
card and delete an image, you may experience a
several minute delay while ˇ°house cleaningˇ± is performed on the
memory card. Because of this, do not delete images while you are
taking pictures. Instead wait until you are at home, your hotel or in the
car before reviewing your pictures and deleting the ones you don't
want. Smaller cards take less time for this ˇ°house cleaningˇ± so many
experienced digital camera owners will choose to have more than
one medium sized memory card instead of one very large one.
Now the question arises-how many memory cards are enough for
your camera? On an average basis, you must have at least two
memory cards for your digital camera. That is, if you are using it in a
normal and average fashion.
Most professional photographers choose to carry about four to six
memory cards. This helps them shoot smoothly and constantly. If they
run out of memory, they just take the loaded card out and insert the
fresh one. Because memory cards can malfunction (just like
traditional film canisters, but not as often), you should choose to have
at least two memory cards at all times. By having at least two cards,
you can work with one and keep the other in reserve for emergency.
Having at least one extra memory card for your digital camera will
also ensure that you have the backup protection needed if you run out
of space on your first card or in the possible event of the first card
malfunctioning.
The next important issue is how to take proper care of these memory
cards. The memory cards may seem like some small and fragile
piece of technology, but they are actually fairly sturdy. The flash
memory is encased in a stiff plastic shell which can withstand normal
wear and handling. At one end of the memory card is either a set of
little holes orcopper strips. These are the sensitive part of the card.
Any voltage source or a large jolt of static could corrupt the memory
and probably cause permanent damage to the card. When the card is
not in your camera, it is best to keep it stored in a protective case or in
your camera case. Putting it in your pocket could cause a short (from
your keys perhaps) or dirty the electrical contracts. There have been
instances where the users have misbehaved greatly with them and
the memory cards have yet survived and continued to function
correctly. But, this does not mean that one should not care for them.
When it is time to transfer your data from the memory card to your PC,
it is best to have a memory card reader, or have a PC with a built-in
reader. The data cables provided with most digital cameras are very
slow compared to the speed of a ˇ°direct readerˇ± and it is often easier
to review, copy and delete images from a memory card when using a
reader instead of through the data cable connection.
When traveling, X-Rays have never been shown to corrupt the data
on, or damage, a digital camera memory card. The memory card is
also not magnetic in nature so the motors in the X-Ray machine's
conveyor belt should not be able to cause any harm either.
Armed with knowledge comes the power to benefit from that
knowledge. If you have learned something new about digital memory
cards, hopefully you will benefit by enjoying your digital camera more
and finding more opportunities to take great pictures.
