Reflex are advanced, high-end cameras by professional photographers and fans favorite. SLR photographers who tend to because they are faster, take more photographs, and are more flexible.
Have you ever had a camera and I noticed that the pictures you have is a bit 'off-center the image framed through the viewfinder, especially for close-up? This is because they are not the real objective of the camera shutter and the film-look (or, in the case of digital cameras, the image sensor) in the path. Thus, the viewfinder is off the real objective of the camera, which are in two slightly different angles.
Reflex solve this problem by using mirrors and prisms to look through the lens of the photographer. It achieves this through the reduction of a mirror in the lens. The mirror reflects the image coming through the lens upward into a prism, which in turn moves the image in the viewfinder. In this way the photographer can see exactly what the camera saw, you got except for the brief moment when the picture.
At this point, the mirror rotates from the path to the lens. The shutter is opened, the exposed film or image sensor, the light through the lens. The image is captured, it closes the shutter, the mirror is lowered again, and also allows the photographer to see through the viewfinder.
The introduction of digital "point and shoot" cameras changed the game a bit '. Moreover, they allow the photographer to see exactly what the lens can see. They are, however limited, that some professional photographers feel useless. The main disadvantage of commercial digital cameras is a significant delay between the moment when the photographer presses the button, and when the camera actually captures the image. During the second that the camera can be pushed to change the angle, the shift lens focus or theme that you can move photographed. Although still fully maintained in order for the images, the photographers who need a photo immediately, such as sport, for example, action, or photographs of any kind, as the unacceptable delay.
A new generation of digital SLR (DSLR) combine the advantages of both technologies. Get the reflex mirror system to allow the photographer to see exactly what the lens sees. Simply replace the film behind the shutter instead of a light sensor, digital image, a DSLR camera is still capable of capturing images immediately. In this way, a DSLR camera combines the precision and speed of an SLR camera with the convenience of digital cameras.
DSLRs are intended as a rule high-end machines for the professional market, tend to be more expensive, but also include other advanced features. A DSLR camera media typically includes options for auto-focus, live preview, control electronic flash, the ability to swap, special lenses and electronic adjustment of digital images captured, how to optimize the contrast and color, red-eye correction black and white options, among many others. DSLRs tend to have even a larger digital image sensor, better image quality with a higher pixel resolution, lower noise and a greater range of colors. While the price of DSLR cameras make a financial investment, professional photographers and fans will consider it worth it.
