... Focal length can change the feeling of a shot. Depth of field can change a character’s size as they move within the frame and represent a character’s size relative to other characters within the frame. Wide Angle lenses provide greater depth of field, so action can be staged in depth. Teleph ...

Graphene-like optical light field and its interaction with two
... We note that the generated light field differs from that given in Eq. (1) as it originates from disks rather than points spaced around the vertices of a hexagon. This is necessary to increase efficiency, but results in a pattern with an intensity that is falling off rapidly around the beam waist, as ...
