The digital cameras have the ability to display the images on the screen immediately after the image is recorded. The images to be captured can be seen on its screen instead of its viewfinder. This way you can get a clearer preview of the image you are intending to capture.

The digital camera outdoes the traditional film camera in its image storing capacity too. The digital camera has the ability to store thousands of images on a single memory device. In addition you can even erase or unload the captured images onto your computer and reuse the camera’s inbuilt memory. In some cases you can even put a new memory card and store more pictures. Digital cameras also allow you to edit images. When capturing videos, digital cameras have the ability to record sound too, thus making video capturing a fun experience.

There are varied categories of digital cameras:

Video cameras: They are the cameras that exclusively record moving images.

The professional video cameras are the ones used for film production, etc. these have multiple image sensors thus enhancing the resolution of the end product. These do not have a inbuilt VCR or microphone.

The camcorder is another type of digital camera that has a microphone to record sound and an LCD screen to view the image that you are going to capture. This is mostly used by amateurs.

The web cameras are the type that is attached to the computers. Some of these web cameras have microphones, while some of them also include zoom abilities.

Compact digital cameras: They are small and portable; the smallest of them are called subcompacts. They are easy to use with not many special features or high picture quality. They have built in flash of not a very high power, but sufficient for close objects. It also permits live preview. They have a greater depth of field thus allowing objects from larger distances to come in sharp focus.

Bridge cameras: They are higher-end digital cameras that look a lot like Digital SLRs. Bridge cameras have the same advanced features as SLR and the live preview like the compact digital cameras.

Digital single lens reflex cameras: This is the digital camera that works like the single-lens reflex with a film.

Digital rangefinders: A rangefinder is an optical mechanism used to measure subject distance. They were once widely used on film cameras.

Professional modular digital camera systems: Mostly these cameras are used in studios for commercial production. Since they are bulky and difficult to carry they are rarely used in action or nature photography. They can be changed to digital or film cameras by simply replacing the back part of the entire device.

Line-scan camera systems: This type of camera is used in industrial areas in order to capture an image of a constant stream of moving material. This technology has the ability

These cameras are almost solely used in industrial settings to capture an image of a constant stream of moving material. Line-scan technology is capable of capturing data extremely fast, and at very high image resolutions.
