Saving and Digital Camera Image

An important characteristic of a digital camera is the support were the images are recorded. The first models saved the image on a diskette (magnetic support), which is still used as a recording medium in cameras which offer a relatively low size in pixels. While the size of the image has grown, new memory supports with more capacity have appeared in the form of sold cards (chips): the majority of medium and high quality cameras use cards ( compact flash, smart media or memory stick ), with maximum capacities superior to 100 MB. With the diffusion of the compact disc (CD) as a large capacity support medium, cameras have appeared which record directly to them. The main difference between diskette or card supports to discs

is that in the first you can save and erase from the camera what interests us but on a recording disc (CD-R) it's permanent and we can only erase the memory if we use ReWritable disc (CD-RW), which can be completely erased (normally on the computer) before being reused. For very large file sizes the cameras have to be connected to an external memory device, whether it's a zip recorder or a CD, or a portable hard drive, or directly to the computer.
