The size of CF cards can start at 4MB up to several GBs (Gigabytes: 1GB = 1024MB). So this way we have a quick and easy to store large amounts of information, which in our case will be pictures on the improved resolution and therefore larger. We could compare the cards with the camera film 35mm machines, since the exhaustion of available space, we can introduce a new card and continue with our work. We note that these memories can be re-write, that is, once we took pictures and got off to a computer or print them, we can erase and reuse. Very few machines cheap (they are little in our market) still have memories, that is, not interchangeable. The big drawback is that there is no way to expand the capacity, so I do not recommend they buy a model. Returning to memory cards, we have several of them available.
The most widespread are the Secure Digital (SD), Compact Flash (CS), Memory Stick (MS), although other models such as Flash and SmartMedia XD. Here are some characteristics of each: – Compact Flash: is the format used in digital cameras, but is also used for other devices. There are two versions: Type I and Type II. The Compact Flash Type I have a maximum capacity of 256MB while the Type II reach several GB capacities. This type of card is not only the most used, but also the one with more support from different manufacturers. It is used by Canon, Nikon, Casio, Minolta and HP among others.
