Disclosure Devices
Introduction
Controlling the amount and the sequence with which information is shown to
a viewer is known as progressive disclosure. Any device or method used to
control disclosure is a disclosure device.
Analog or
digital
programmers
Analog or digital programmers are disclosure devices that make text appear
to roll onto the screen without disrupting regular television programming.
Weather bulletins are an example of the use of an analog or digital
programmer.
Tilt cards
Vertically oriented cards whose information exceeds the capabilities of the
camera and requires an up and down motion of the camera to transmit all
information are known as tilt cards. Use tilt cards only for creative effects or
when it is not possible to divide visuals into smaller segments.
