at least five reasons every
In the early times of digital photography, the best possible way to download images from the
digital camera to a computer was with a cable. The interface was usually USB, but some early
cams used SCSI or Firewire connections as well. As sd cards became popular, card readers
appeared, enabling users to quickly transfer photos from these cards to their hard drive.
Surprisingly, even today, countless digital photographers still transfer their photos to their pc via a
universal serial bus cable. Card readers are inexpensive, faster and a lot more reliable, yet many
digicam owners still haven't bought one.
1: Card readers offer high speed transfers
Without a doubt, the key advantage to a card reader is speed. Photos transfer at a rate several
times compared to a camera USB connection. Obviously, It is advantageous whenever you can
cut the photo transfer time period. As memory cards increase in capacity and digital cameras offer
bigger pixel density, however, transfer rate becomes a serious problem. My first digital camera
only had 8MB of storage memory, and I felt it took quite a while to transfer the photographs to my
hard drive by universal serial bus cable. Nowadays one single raw picture could be twice that
size. A card with 30 or forty pictures of that size would definitely take a long time to transfer by
2: When reliability is a priority, choose a card reader
While speed is important, reliability is vital. The problem with connecting a digital camera to your
computer is that the digital camera has to be on all the time the transfer is being executed. If the
battery dies during the transfer, the transfer will be lost. additionally, there is a danger that the
memory card will be corrupted if the power goes down during a read. It's true that the majority of
modern cameras have longer lasting batteries, but sd cards are also getting larger, so that might
not be much help. Some camera manufacturers actually recommend that the device be powered
by an AC cable during the transfer, in order to alleviate any problem of the battery failing during
There are no power consumption issues with a card reader. Power comes straight from the
universal serial bus or Firewire connection. Unless there's a major power failure or the pc fails, the
power to the card reader will always be consistent.
3: digital cam connections are plug and pray
Plugging in a camera to the laptop is very easy, but I have experienced many instances where the
desktop computer refused to recognize the digicam. Rebooting the machine usually fixes the
issue, but that is still an annoyance.
In contrast, card readers are basically found immediately by the personal pc. Plug the reader in,
insert the memory card and you can start downloading your photos.
4: Card readers allow you to walk away
Once you've started a download, you are free to do other things. Eat dinner. Watch Television.
Take a walk. Even hit the sack for the night. You don't have to "baby-sit" the file transfer process.
I wouldn't feel comfortable leaving my camera unsupervised in the "on" mode for an extended
length of time. Maybe I'm being too old-fashioned, but leaving my cam on overnight simply
doesn't seem wise. With a reader, there's no off or on. Once your data transfer is done,
everything just waits until you get back.
5: You are free to use your cam while your files transfer to the laptop
If your digital camera is hooked to your personal computer, transferring photos, you obviously
can't be off taking pictures. In contrast, you can put a sd card into your reader, initiate a file
transfer and then load a new card into the dslr camera and continue taking pictures. The ability to
download images while you're off shooting new ones is yet another major advantage to a reader.
So what exactly are you waiting for?
If you're serious about digital photography, I honestly suggest you throw away that Universal
serial bus cable and buy a reliable card reader. You'll shortly think how you ever got along without
