how does a digital camera work and how many pictures can you take?
“A digital camera is an electronic device used to capture and store photographs electronically instead of using photographic film like conventional cameras”.
So, it needs to be powered to be able to be used.
Most cameras either use AA size batteries, and others use rechargeable Lithium batteries. (the most cost effective way is to buy rechargeable AA’s if your camera uses them).
All cameras require a memory card to store pictures…and these cards are available in certain types (Secure Digital, SD…Compact Flash, CF…xD-Picture Card etc).
and they are available in certain capacities.
So, dependant on which type of camera and how many megapixels (MP) it has, you buy a card which would suit your needs.
e.g…a 6mp camera which uses a 512MB memory card can take approx. 170 photos…a card half that capacity (256mb) can take half that number etc etc.
