If you are serious about digital photography, I suggest you ditch that USB cable and get a good card reader.If you’re a photographer or videographer, one of the most important tools in your kit is a memory card reader and writer. The ability to transfer pictures while you are off shooting new ones is yet another major advantage to a reader. In contrast, you can load a memory card into your reader, start a file transfer and then load a fresh card into the camera and continue making images. If your camera is tied to your computer, transferring files, you obviously can't be off shooting. When your file transfer is completed, everything just waits until you return.ĥ: You are free to use your camera while your files transfer to the computer Maybe I'm being too conservative, but leaving my camera on overnight just doesn't seem wise. I wouldn't feel comfortable leaving my digital camera unsupervised in the "on" mode for an extended length of time. You don't have to "baby-sit" the file transfer process. Once you've begun a transfer, you are free to do other things. Plug the reader in, insert the memory card and you can start transferring your files. In contrast, card readers are generally found immediately by the computer. Rebooting the computer typically fixes the problem, but that is still an annoyance. Unless there is a major power outage or the computer crashes, the power to the card reader will remain stable.ģ: Digital camera connections are plug and prayĬonnecting a camera to the computer is fairly simple, but I have experienced many instances where the computer refused to recognize the camera. Power comes directly from the USB or Firewire connection. There are no power consumption worries with a card reader. Some camera manufacturers actually recommend that the camera be powered by an AC cord during the transfer, in order to alleviate any problem of the battery dying during the copy. It's true that many newer cameras have longer lasting batteries, but memory cards are also getting larger, so that might not be much help. Even worse, there is a danger that the memory card will be corrupted if the power goes down during a read. If the battery dies during the transfer, the current transfer will be lost. The problem with connecting a camera to your computer is that the camera has to be on all the time the transfer is being executed. While speed is important, reliability is crucial. A card with thirty or forty images of that size would take an eternity to transfer by cable.Ģ: When reliability is a priority, choose a card reader Today a single raw image could be twice that size. My first digital camera only had 8MB of storage memory, and I felt it took a long time to transfer the images to my hard drive by USB cable. As memory cards increase in capacity and cameras offer greater pixel density, however, transfer speed becomes a major issue. Obviously, It is advantageous anytime you can shorten the image acquisition period. Images transfer at a rate several times that of a camera USB connection. Undoubtedly, the biggest advantage to a card reader is speed. Card readers are inexpensive, faster and more reliable, yet many digital camera users still haven't acquired one. Surprisingly, even today, many digital photographers still transfer their images to their computer via a USB cable. As reusable memory cards became popular, card readers appeared, allowing users to quickly move images from the card to their hard drive. The interface was usually USB, but some early digicams used SCSI or Firewire connections as well. In the early days of digital photography, the only way to transfer images from the camera to a computer was with a cable.
