5 top reasons Every Digital Photographer must have A Card Reader
In the early days of digital photography, the best possible way to download files from the digital camera to a computer was with a cable. The interface was usually universal serial bus, but some early digital cameras used SCSI or Firewire connections as well. As memory cards became popular, card readers were introduced, enabling users to quickly move pictures from these cards to their hdd.
Believe it or not, even today, countless digital professional photographers still transfer their photographs to their pc via a universal serial bus cable. Card readers are inexpensive, faster and more efficient, yet many digicam users still haven't purchased one.
1: Card readers offer high speed transfers
Undoubtedly, the key advantage to a card reader is speed. Photographs transfer at a rate several times compared to a camera universal serial bus connection. Obviously, It is advantageous when you can cut the photo transfer period. As memory cards increase in capacity and digital slr cameras offer bigger pixel density, however, transfer speed turns into a serious issue. My first digital cam only had 8MB of storage , and I felt it took a lot of time to transfer the images to my hard disc drive by universal serial bus cable. These days a single raw image could be twice that size. A card with 30 or forty files of that size would definitely take forever to transfer by cable.
2: When reliability is a high priority, choose a card reader
While speed is important, reliability is vital. The downside to connecting a digital camera to your personal computer is that the digital cam has to be switched on all the time the transfer is being executed. If the battery dies during the download, the transfer will be lost. On top of that, there is a probability that the memory card will be corrupted if the battery crashes during a read. It is true that many modern digicams have longer lasting batteries, but sd cards are also getting larger, so that might not be much help. Many cam manufacturers actually recommend that the camera be powered by an AC cable during the transfer, in order to minimize any issue of the battery failing during the copy.
There are no power consumption worries with a card reader. Power comes right from the USB or Firewire connection. Unless there is a major power outage or the desktop computer crashes, the power to the card reader will always be consistent.
3: dslr camera connections are plug and pray
Plugging in a camera to the computer is pretty simple, but I have experienced many instances where the computer refused to recognize the digicam. Rebooting the machine typically fixes the problem, but that is still an inconvenience.
In contrast, card readers are basically found instantly by the home pc. Plug the reader , insert the memory card and you can start transferring your data.
4: Card readers allow you to walk away
Once you've started a download, you're 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 download process. I wouldn't feel comfortable leaving my digital camera unsupervised in the "on" mode for an extended amount of time. Maybe I'm being too cautious, but leaving my digicam on during the night simply doesn't sound a good idea. With a reader, there's no off or on. When your file transfer is done, everything just waits till you get back.
5: you're free to use your cam while your pictures transfer to the personal pc
If your digital camera is tied to your home pc, downloading pictures, you obviously can't be off taking pictures. In contrast, you can put a sd card into your reader, start a file transfer and then load a fresh card into the digital camera and continue taking photos. The ability to download photographs while you are off capturing new ones is yet another major advantage to a reader.
So what are you waiting for?
If you are serious about digital photography, I honestly suggest you ditch that USB cable and get a reliable card reader. You'll soon wonder how you ever got along without one! facebook page
