Currently in among regular users of digital cameras, there are two main types of storage media available today. Some cameras use 1.44 MB disks, which are available almost everywhere in the present market, and some digital cameras use various types of flash memory with a range of capacities covering from several mega
bytes to a gigabyte. The difference between these two types of disc formats in their capacity. Disks have a permanent memory that can not be changed, and flash memory devices have capacities that keep increasing everyday. This is a kind of a blessing, because the fact that the image sizes is also increasing constantly with the invention of higher resolution cameras are available in markets with daily technical progress.
The major and most popular file format available for digital cameras are TIFF and JPEG formats, respectively. Looking at a small detail in the two formats, the TIFF format is an uncompressed format without modification of image sizes and JPEG is a compressed format that changes the image size for economic use of memory for storage. Certainly, from common sense, most digital cameras use the JPEG file format for storing images and photos, and they even offer quality environments such as medium or high, and therefore the size is changed so as to provide both memory management, and quality of the images.
Again, look at the disc formats from a different angle, it is clear that a 1.44-MB disk can not clutch many photographs or images. Sometimes, in fact, they can not even fit an image on a disk, due to high quality and subsequent seizure and memory. But the disks have their own advantages. In today's world of Internet publishing and e-mail an image that is larger than 640x480 is hardly required, and more or less always they are saved in JPEG format. During these times it is possible to accommodate about 15 images on each disc. And thus making situations more economic and flexible for users. But for storing larger and better quality pictures higher capacity media are required, such as a 128-MB flash memory card that can store more than 1,500 small compressed images or 20 of uncompressed 1600x1200 images.
Thus far a handsome amount of information about the disc formats has come into the light of the foregoing discussion. It is a humble effort to bring the rudimentary knowledge of such a broad field of study as digital camera disc formats, which include photography and computers in one. What a great combination!
