This viewfinder would be like a screen that projects what is about to be immortalized in a photo.

SLR cameras work as follows: first the photographer chooses the frame that can be viewed in the viewfinder thanks to the mirror that the camera has. Then it focuses and that's when the mirror is stowed away and the shutter is released. Thanks to this, it manages to pass the light that specifies the final image.
