As it is a fact that digital cameras are comprised of miniature computers that have storage discs for retrieving images as digital information, so a certain amount of knowledge is necessary regarding digital camera disc formats. A proper understanding of disc formats of digital camera memory can help photographer or user make efficient use of device in a correct and useful fashion. This discussion is aimed at revealing these little details!

At present in among common users of digital cameras there are two main types of storage medium available nowadays. Some cameras use 1.44-MB floppy disks, which are available almost everywhere in present market trends, and some digital cameras use assorted forms of flash memory having a range of capacities covering from several megabytes to a gigabyte. The difference lies between these two types of disc formats in their capacity. Floppy disks have a fixed memory capacity that cannot be altered, and flash memory devices have capacities that keep increasing everyday. This is a kind of boon because of fact that picture-sizes are also increasing constantly with invention of higher resolution cameras that become available in markets with daily technical advancements.

Every device needs a driving force to operate, just as every living thing needs a heart to keep it alive! Basically electric power does this job for any kind of devices nowadays. Similarly for any digital camera too, a good battery is necessary in order to ensure an excellent performance from it as long as possible. Being such a crucial task as if searching for a good heart for a human being, perhaps most tedious thing about digital cameras is quest for their battery consumption and thereby finding a suitable one for any particular one. Yet a basic overview regarding this so important component of a digital camera makes ventures of users somewhat less complicated and makes life easier with a proper selection of battery!

Leaving aside ever power thirsty LCD screens and flashes, digital cameras themselves exhaust batteries much faster than film cameras, due to their state of art electronic designs and intricate circuitry. Many digital cameras run from AA cells, around 4, and can even drain a set of alkaline cells in less than 1 hour of working! For example, Kodak DC120 draws about 210mA during start or switch ON, but progresses to around 1.3A with association of LCD fully working and can go ahead to about 2.1A while picture taking and after it too.
