most cameras, the view camera has the ability to alter the planes
of the film and lens to control both depth of field and perspective.
The view camera generally has four basic movements or adjustments
that allow these "corrections" to be made. These adjustments
allow the lens board and the ground glass to be realigned independently
of each other.
four movements are listed in the next pages:
Rise and fall - vertical movement.
This movement can be used with the
front standard where the lens is and the rear standard
where the ground glass and film are.
