A one-gigabyte memory card holds between 13 and 715 pictures at one time, depending up on how many megapixels each photograph contains. A card can hold more compressed files than raw photographs that haven't been compressed for easier storage. For example, a one-gigabyte memory card holds 715 compressed picture files if each photograph has four megapixels. The same capacity card holds 13 raw photos at 22 megapixels each.Continue Reading
For Kodak memory cards, a one-gigabyte card holds 260 six-megapixel photographs and 45 16-megapixel photographs. Sandisk cards contain up to 71 raw, unprocessed photos at four megapixels each. The same capacity can hold up to 715 four-megapixel photographs in compressed form.
The difference in memory storage is based upon the size of each saved file. A compressed four-megapixel photograph requires 1.2 megabytes of memory, versus 12 megabytes for a raw photo with the same megapixels. If a removable drive holds more memory, more pictures can potentially be stored on the disk.
A megapixel, abbreviated as MP on digital camera specifications, refers to the resolution of the photograph. One megapixel is equal to 1 million pixels, and a pixel is smallest individual element of one photograph. A digital photograph with 10 megapixels has a higher resolution than a photograph of five megapixels.Learn more about Digital Storage
