Increased Depth of Field for Motion-Picture Photography

The development of wider screens and larger camera apertures has brought about a need for increased depth of field. A practical comparison is made of lens focal lengths commonly used. Depths of field are shown in relation to focal distances and f-stops. An accurately calibrated camera aperture which pivots on its vertical center is proposed as one means of increasing the depth of field across the picture area.
