The Single-lens Reflex Camera

The Single-lens Reflex Camera. A camera consists of a lens, a light-tight box, a shutter, and a sensitized plate or a film Shutter speed refers to how long the shutter is open and the film exposed The amount of light must be controlled to avoid overexposure or underexposure
