Viewfinder Interchangeable Lens

A camera or camera, is a device that allows you to capture, record and store images or photographs. There are basically two types of camera, analog, own analog or chemical photography employing physico-chemical methods to obtain and process the photographs, and digital, used in digital photography which is an electronic sensor which is responsible for capturing images that subsequently are stored in a computer in digital format memory. Analog photography and digital photography we can differentiate two types of photography, photography analog or chemical, which is based on physical and chemical procedures for obtaining and processing of the images, and digital photography, where images are captured by an electronic sensor and archived in digital form in an electronic memory. In this way, we can distinguish two types of camera: analog camera: records the images in photosensitive film, and must resort to processing in laboratory to access the recorded images. Digital camera: capture images using an electronic sensor and stores them in memory in digital format, allowing access to recorded images instantly. Analogue photo camera types there are numerous types of analog camera: Compact: camera simple, economical, with no interchangeable lens, light and easy to transport, very suitable for traveling. Reflex SLR (Single Lens Reflex, single Lens Reflex): the image that shows the viewfinder is exactly the same that will be captured. Reflex TLR (Twin Lens Reflex, twin Lens Reflex): they have two objectives, one for taking the photo and another to generate the image in the viewfinder.

Studio camera: camera mounted on Rails to allow for tilt and decenter panels front and rear, getting an absolute control over the form and image perspective. Panoramic camera: allows a wide angle of vision without distortion. Camera bellows: large and medium format cameras that have a folding bellows which allows you to move the objective with regard to the film. Digital photo camera types there are different types of digital camera: Compact and ultra-compact: cameras small, simple and little configurable, but comfortable to carry. Bridge: intermediate photo camera between the compact and SLR in size, price, functionality and quality. SLR DSLR (Digital SLR): digital version of analog SLR SLR, where an electronic sensor replaces the photosensitive film. The conventional DSLR have a sensor with form factor 3: 2, as the negative 35 mm, while the Four Thirds sensor (reflex 4/3, four thirds) has a form factor 4: 3. Micro 4/3 (Micro FourThirds, Micro four thirds) or EVIL (Electronic Viewfinder Interchangeable Lens): intermediate between the SLR and the compact camera has a Four Thirds sensor but without mirror viewfinder. Digital camera integrated: many electronic devices such as mobile phones, PDAs or tablet PCs have built-in camera, increasingly higher quality.
