A digital camera card is a device that serves as a storage place for your photos until you upload them to your personal computer.
It is different from the digital camera's internal memory.
Memory is available in different sizes.
If you always take a lot of pictures, you will need a memory card that is large enough to store all these images.
If you shop at malls or through the internet, you will find that these cards have varying capacities for holding image files.
Some can hold up to 4 gigabytes of images while smaller cards can hold only 128 megabytes of pictures.
Today, the most common digital memory card that people use is the one that can store about a gigabyte of images.
Professional photographers might need cards that can hold bigger files.
They usually use those two to four gigabyte chips.
If you shoot pictures at very high resolution, the tendency is that these images may occupy a large amount of space in the memory card.
That is why people who take photography seriously purchase the bigger digital memory cards so that they are assured of high quality photos every time they shoot.
It is also important to decide how much money you are willing to spend for the card, how many photos you think you will need to store in it, and how high or low the resolution that you are going to use for these pictures.
Another factor that you might want to consider before buying a digital card is the number of pixels that your digital camera has.
If you are using a six megapixel camera, you might want to buy a one gigabyte memory card so that you can store about 300 hundred images in there.
Some of the most popular names in the production of memory cards are ScanDisk, Fuji and Transcend.
