SLR cameras have appeared long ago, but now it goes not about the history of cameras, but namely about digital "SLR cameras" as they are commonly called. Why are they called reflex? Everything is very simple - the design of this camera includes - a mirror. Thanks to it we can see the image before making the frame.
The design of all SLR cameras is the same: the light passing through the lens comes on the mirror, it is reflected and gets on the prism, and you see a picture. After pressing the shutter, the mirror is raised, and for a split second the shutter opens through which the light is imprinted on the photosensitive matrix - the heart of every digital camera. Then the image of the matrix is stored in flash memory for the later use - everything is simple!
So, what is the difference between reflex and conventional camera. At first glance it is possible to see the distinction only in sizes, but this is only for fans of photography, but in fact the fundamental difference is in the absence of the same system with a mirror.
The fact is that ordinary cameras are arranged much easier then SLR cameras: the light passing through the lens immediately hits the matrix, so you are able to see the image on the screen at once. But due to the fact that the light gets into the matrix permanently - we have too much light, and the camera has to "filter" the picture, that is to impose all sorts of filters - brightness, contrast, gamma, color saturation, and this is not the complete list! Thus we get not a real depiction, but only the picture that the camera sees.
Sure thing, you don't have to think that usual cameras are bad, their main benefit - is the compactness and convenience at use. Reflex cameras are difficult in management and setting, even in automatic modes, so they are applied by professionals. For a everyman it is sufficient a usual camera.
