Digital Photography Transferring
Images
After shooting enough photos to
fill out up your memory cards you need to transfer images
to a computer or printer. There are a few ways
to do this.
USB port allows the digital camera to be
connected directly to a computer for image downloads. There are
two versions of USB – USB 1.1 and USB 2.0. High-end cameras are
usually equipped with USB 2.0 because the transfer rate is up
to 10 times faster than USB 1.1. Budget cameras usually have
USB 1.1 –
sufficient, however other options may be more
attractive.
They can reading images from the memory card
instead of directly from the camera. Most multimedia
notebook and desktop computers can read cards directly. If this
is not the case you may need an external card reader.
Card
readers
Card readers are one of the most efficient ways to transfer
images. You can simply take out the card from
your camera and pop it into the reader. Most card readers have
a variety of ports designed for different kinds of memory
cards. Card readers are almost always equipped with USB 2.0 or
FireWire -- an equally fast data transfer protocol. They are
quite reasonably priced.
One of the advantages of USB devices is that they can be
connected to the computer while it is turned on. The computer
will recognize the card reader as an external storage device
and allow you to transfer data to any location on the
computer's hard drive.
Other
Options
Storing images on a computer hard drive is the most
practical solution. Computer storage allows images to be
edited, sent as e-mail attachments, or posted to a web
site.
Another way to transfer images is to use the camera's video
output to connect it to a TV, VCR, or DVD burner. Images could
be captured on videotape or burned to DVD, or simply viewed as
a slideshow on a TV screen. Some cameras are equipped with an
infrared remote control which allows you to flip through the
pictures from your armchair.
However, there are other ways to download images from your
camera. Cameras with a PictBridge or USB Direct Print can be
connected directly to a compatible printer for direct printout.
This is a very convenient way to download pictures but by doing
so, you miss out on the opportunity to edit them on the
computer.
Portable
Storage
Portable storage devices are specifically designed to hold
large numbers of images so that they can later be transferred
to a computer. They are primarily aimed at the professional
photographer who shoots several gigabytes of photographs per
day. These devices are useful when you are on vacation and
taking plenty of photos and don't have easy access to a
computer.
These devices have an internal hard drive and are powered
with rechargeable batteries. They read the camera's memory
cards so that they can be erased and used again. They are often
equipped with a LCD viewing screen so that images can be
previewed. Images are transferred to the computer by USB 2.0 or
FireWire.
