Although many digital cameras may have the look of a traditional camera, they are fundamentally different.
Digital photography is unique in how it captures and stores an image.
The functions of a digital camera are based on digital imaging technology. This technology uses an electronic image sensor and microprocessor for image capture. Instead of film, digital imaging technology uses a grid of many very small sensors that translate what enters the lens into data. Once a photo is in the camera's memory, it is ready for printing, viewing, or unloading for storage on a computer hard drive. Choosing a Digital Camera Like film-based cameras, the more you pay equates to higher quality, better resolution, and more features when purchasing a camera.
