What Is A Digital SLR Camera?

Author : Rick Valence


Digital SLR, or DSLR, is an acronym for digital single lens reflex camera. The fundamental difference between digital single lens reflex cameras and traditional film SLR cameras is how the image to be photographed appears to the user. In a DSLR, the image appears typically through the LCD with accurate final picture details such as focus, depth of field, lighting, etc. In film cameras the user can only see what the final picture will be like through their own perspective, i.e. how they view the final shot image. This is significantly different from how the camera sees the final image, making it difficult to correctly set such elements like focus and flash intensity.

The DSLR uses CCD micro chips, a device that can detect, shift, and convert electrical charge into digital signals. These micro chips transform incoming light rays from the lens of the camera into a digital picture. In principle, the more light the sensors can detect, the sharper an image will be. DSLR cameras can produce very high resolution pictures and most of the time, depending on the camera, can provide better shot to shot progressive exposure.

A DSLR takes away the need to develop film. With most households owning a computer and printer these days, anyone with this type of camera can easily print their own photographs at a fraction of the cost and time it would normally take to develop film in a studio. As with traditional film SLR's, they normally have interchangeable lenses with varying focal lengths that increase zoom and resolution of the final shot. The convenience that these cameras have over their counterparts makes them slightly more expensive, though cost depends heavily on the type of lenses used.

The popularity of DSLR's is mostly with serious photography hobbyists and enthusiasts. Professional photographers such as journalists and reporters for magazines are known to prefer digital SLR'S as well. They are purposely built for speed and are equipped with high speed shutters. This makes them more appropriate for use in situations in which the image to be photographed is in motion (for instance in a sports event). They are also more highly sensitive to light to the extent that in cases where there is low ambient light, a photograph can still be taken.

All things considered a digital SLR is the way to go for professional photography. They have slowly begun to replace the technology of older models, and as their prices continue to decrease, more and more people will consider them for their needs.
