CHAPTER 4
of Still Picture Projector AP-5 (1) . It is recommended that a standard projection
screen and a firm support for the projector be available for use.
33. Projection Screen
An 8- by 8-foot semimatte projection screen is recommended. The
semimatte screen is less bright than a beaded screen when viewed
head on, but it will maintain a uniform brightness when viewed from
any angle. If no screen is available, any flat, light-colored wall or
surface may be used with fair results.
34. Projector Support
A solidly built table or other support with a minimum top surface
of 18- by 24-inches is recommended for mounting the projector. For
convenience, the table should be approximately 36 inches high when
the operator is in a standing position.
