Digital Memory Cards. Friend or Foe

Copyright (c) 2008 Tom Jackson

The method used to record images in modern digital cameras, from compact the professional DSLRs, is the memory card. These little wonders of technology can store thousands of images, and if not treated carefully, can also destroy your images.

Film cameras usually had many fewer choices to be made when taking photos, they were relatively simple and therefore somewhat foolproof. You went to the drug store and bought a roll of film, either 24 or 36 exposures, popped it in the camera, and started firing away. When you finished the roll of film in old traditional film cameras, your job was done, you just took the film to the store for processing. In a day or two, or in more recent times, an hour or two, you came back and picked up all your beautiful prints. These were ready to show everyone who would look at you beautiful new photos. In the days of film, there were little choices to be made, the speed of the film or the ISO number (still needed to be set on digital cameras), if you were taking photos inside or out and the number of exposures on the roll, 24 or 36.

In those days, losing a roll of film, either because you misplaced it, or the drug store screwed up on the processing, was not always too big of a deal, as you usually had several more rolls of film with other photos to choose from. But in this digital age, just one memory card can store hundreds of photos, even thousands if you shoot in low resolution mode. So, if you lose a memory card, it can be a really, really big deal. That?s why it is important with digital, to have a special case to store your memory cards, to help avoid losing one.

One of the biggest problems though, is, unlike film, memory cards can be very sensitive to the way they are treated, and hence it is very easy to accidentally lose a lot of photos. In this article I will try to spell out some of the precautions you need to take to avoid problems.

Step 1. Always try to purchase a good quality card, from a camera store if possible. The staff at the camera store will usually always be able to offer good advice and a quality card for your camera. A good quality card can sometimes cost a little more, and I am talking about just a few dollars more, than a cheap budget card from the drug store. Sometimes, the drug store card may be ok, but I think it is always prudent to make sure you have a quality product, one that you can get advice about from an expert, and where you will not have any problems returning the card if you have to for any reason.

Step 2. The first thing you need to do when you purchase a new memory card, is to format the card in your camera. This step is crucial. Digital cameras are not all the same, and the card can cause problems, even if you format the card on your computer, instead of the camera. If the card does not format, or you get errors when the camera tries to format the card, then you need to return it immediately to the store for a replacement. Note that not all cards are compatible with all digital cameras. Most of the low end and even high end compacts, have an upper limit as to the memory size of the card that can be used.

Step 3. Never take the card out of the camera while the camera is still writing the file to the memory card. Often, people will take a photo and then almost immediately take the card out of the camera. This can easily corrupt the card and make it impossible to get the images off the card into the computer. If you need to take the card out after taking a shot, just wait for several seconds to make sure the file has been written completely to that card, I usually suggest about 20-30 seconds. This should ensure that the file is safe and sound on the card.

Step 4. Never take your memory card and put it into another camera without formatting the card on the new camera. This means of course, that you need to back up all the files on the card, then put the card into the other camera and format the card before using. As I mentioned earlier, not all digital cameras are the same, and the way they write the files to the card can be different enough that you will corrupt the card and make it impossible to recover the files you already had on the card.

Step 5. Try to keep the contacts of the memory card protected from the elements and any dirt or grease. If the contacts become oxidized or too dirty to work effectively, then you will not be able to record the photos you think you are taking. This can be very embarrassing later when everyone wants to see the results.

Step 6. Always make sure that the camera batteries are charged enough so that the camera can write the files to the card correctly. If the camera battery dies during the process of writing the file, you will lose the file and possibly all the files on the card at the time of the problem.

Step 7. As a precaution, you can purchase software specifically designed to recover images from memory cards. This software is quite inexpensive, and may come in very handy if ever needed.

Using precautions such as these can help prevent ever having a problem. I have met other photographers who have had problems, but those problems fell under one of the steps above. I think the most common problems are due to that photographer not formatting the memory cards before each shoot. Always back up the card before any shoot, then format in the camera. The is the best way to help prevent problems before they occur and make sure you are ready to take photos.
