The digital camera is essentially a computer-based device, whose core is controlled by computer. And as a result photographs are stored in a location called memory. Now, this concept is or paramount importance in discussing digital camera. Strictly speaking, digital camera memory is where digital pictures are stored inside camera. The digital camera memory is an essential and often a very neglected and overlooked section of equipments for digital photography and camera. There are many types of memory available for digital cameras, and it is a good practice to mull over what type of memory a camera uses before buying a digital camera. This discussing is aimed in revealing some of this relevant information!
Knowledge of digital camera memory is very essential for using such a camera and capturing photographs. The most common form of such memory is a memory card. These are reusable, have a limited capacity and can always be installed when required in excess. A person needs to be well informed about enough memory available for taking photographs. And accordingly make arrangements. Generally, digital cameras come available with low capacity memory cards, and it is a wise purchase to acquire higher capacity memory cards in order to budget for an additional card for later use.
With increment of a camera mega pixel counts, it becomes essential to use higher capacity memory cards. Some of small sized cards are for example 64 megabyte cards and larger ones are like 1-gigabyte cards or combinations of megabyte cards. Digital camera memory is available in many shapes and facade depending on type of digital camera that is being used and even and number of pictures that are required to be stored in digital camera memory. These different types of memory are solely dependant upon requirements of digital camera, like for example a camera using compact flash type 1, requires use of compact flash type 1 digital camera memory. Other examples of types of digital camera memory are Compact Flash Digital Camera Memory. It is suitable for rugged and rough handling and is also resilient for incessant usage. This is also small in size to assist better handling and flexibility. What more, it is cheap and anyone can afford it!
Digital cameras & resolutionWritten by Jakob Jelling

While analyzing any camera, one of most important qualities of a photograph that a person seeks, is resolution. This word itself needs a brief discussion before progressing onto its implication upon a digital camera. This is a word that seems to almost every new photographer as a nightmare. With all myths and irrelevant information circulating all around, this is quite common. This however is an effort to clear those misty myths and provide good information for everyone. Without any complexity, generally a photograph, either viewed on screen or printed, is composed of infinitesimal dots (called pixels). The greater amount of these dots that can fit per inch of space, smaller dots and sharper image. This is basis of understanding ... resolution!
Considering an image at 100 dots per inch that is one square inch in size. It is comprised of 100 X 100 pixels. Now changing this image four-times to four square inches. This image is quite clear. Now same 100 X 100 dots exist, but with only 25 dots per inch. The appearance becomes grainy. This is factor know as resolution that determines this quality of image. Hence it can now be interpreted by any person what importance of resolution is and where it is required in filed of photography. While purchasing a digital camera, resolution is a very important factor to take into account when settling upon buying a particular one.
Digital camera resolution comes in as Mega pixels. A Mega pixel is composed of one million pixels. The greater number of Mega pixels, greater becomes standard of quality of photograph or picture. As a standard, one mega pixel is minimum bottom line below which a digital camera must not be usually purchased. This is a general decided value for any amateur photographers also, and exact value of higher mega pixels is not a concern for people who do not intend to print photographs. In an effort to scrutinize pixels in an image out of sheer anxiety, a person can magnify display in a photo editor, like a little magnifying glass, and they become very much visible!
