Reflex are advanced, high-end cameras for professional photographers and fans excited. These photographers gravitate toward the reflex, because they are faster, more accurate picture taking, and are more flexible.
Have you ever used a camera and I realized that the photo was taken slightly off center of the image that is framed through the viewfinder, especially in the foreground? This occurs because you can look through the true lens of the camera and the shutter and the film (or, in the case of digital cameras, the image sensor) are on the road. Therefore, the viewer is at a side of the lens of the camera real, in two slightly different angles of view.
SLR cameras solve this problem by using mirrors and prisms to the photographer to see through the lens of the camera. This is achieved by reducing the mirror box, lens. The mirror reflects the image coming through the lens upward into a prism, which in turn passes the image in the viewfinder. In this way, the photographer can see exactly what the camera lens is seen, with the exception of the brief moment when the photograph is taken.
At this point, the mirror turns up out of the box shape of the lens. The shutter opens, showing the film or image sensor to light through the lens. The image is captured, the shutter closes, the mirror drops down, and the photographer can see again through the viewfinder.
The introduction of digital point and shoot "cameras changed the game a bit '. They also allow the photographer to see exactly what the goal is to see. Have limitations, however, that some professional photographers feel they are unusable. The main drawback of the business of digital cameras is a considerable lag between the time the photographer presses the button and when the camera actually captures the image. During those seconds, the camera can be pushed, the change of angle, moving the lens focus, or the subject being photographed can be moved. Although perfectly fine for still images, the photographers must capture a snapshot, such as sports, action, or photographs of wildlife, the delay is unacceptable.
A new generation of digital SLR (DSLR) combine the best of both technologies. Use the system reflex mirror to allow the photographer to see exactly what the lens sees. Simply replace the film behind the shutter of a digital image of the light sensor instead of a digital SLR camera can capture images at once. Thus, a digital SLR camera combines the precision and speed of an SLR with the convenience of digital cameras.
As digital SLRs are usually high-end machines aimed at a professional market, which tend to be more expensive, but also include other advanced features. A cámara reflex digital media generally incluye las opciones de enfoque automático, after having en vivo, los controles de flash electrónico, the habilidad de intercambiar lentes especializados, y el ajuste de la imagen digital capturada electrónico, como que el contraste y optimize color, corrección Red Eye, and options in black and white, among many others. Digital SLR cameras also tend to have larger sensors of digital imaging, which provides better images with a resolution more pixels, lower noise and higher color gamut. While the price of digital SLRs make a financial investment, professional photographers and amateur enthusiasts are deemed worthwhile.
