We more or less see what the camera is seeing. Without the prism and mirror system of the DSLR viewfinder we would be dealing with this.

The image you see while composing a shot through the viewfinder of a DSLR is the result of the following actions:. The light bounces upwards off the reflex mirror more on this later.
