Digital cameras are revolutionizing the world of home and professional photography, but they are married to memory cards just as traditional cameras are married to film. Making the best use of memory cards can have a very big impact on your enjoyment of digital photography. Choosing the right memory card for the job can be as important as choosing the right film for a traditional camera.

Something many new digital camera owners find counter-intuitive is that bigger is not always better with a digital memory card. The actual response speed of your digital camera can depend greatly on the memory card it is using. The speed that your camera writes new pictures to the digital memory card is partially dependant on the transfer speed of the digital camera but is also dependant on factors in the memory card itself. Memory cards that have “buffers” can take the data into a faster type of memory and then transfer the data from there to the slower “flash memory” which provides the main storage of almost all digital camera memory cards. Some digital camera provide their own buffer memory to allow you to take your next picture while the previous picture is being transferred to the memory card.

When you delete an image from the memory card of your digital camera, the flash memory is “reconfigured” because of special issues having to do with how this memory stores data. Normally this is an issue that you don't have to worry about at all. However, if you have a very large memory card and delete an image, you may experience a several minute delay while “house cleaning” is performed on the memory card. Because of this, do not delete images while you are taking pictures. Instead wait until you are at home, your hotel or in the car before reviewing your pictures and deleting the ones you don't want. Smaller cards take less time for this “house cleaning” so many experienced digital camera owners will choose to have more than one medium sized memory card instead of one very large one.

Now the question arises-how many memory cards are enough for your camera? On an average basis, you must have at least two memory cards for your digital camera. That is, if you are using it in a normal and average fashion.
