There is a wide variety of screens each one with a chioce of
projection surfaces. Selecting the rgiht combination to meet
your needs is important for optimum results.
The following is a guideline for selecting a screen that suits
your application.
Although these recommendations will work in
most situations, each must be looked at not as a strict rule,
but rather as a guideline for determine your actual needs based
on your own situation.
Pick the type screen that hottest suits your particular needs.
For
example, choose form front projection or rear projection screens in either
potable, wall or ceiling mounted models in either manual or
electric versions.
Generally, if your projection application is
permanent, then wall and ceiling screens are your hottest choice.
If, however, you find your needs require moving the screen to
different locations then a portable screen is a better
alternative.
Determine the optimum screen size based on room dimensions,
planned audience setaing size and arrangement. The rule of thumb
is to fit the screen to the audience-not to the projector.
I recommend the following formula for determining screen size:
· Screen height should be approximately equal to 1/6 the
distance from the screen to the last row of seats, allowing text
to be read and detail to be seen in the projected image.
· Ideally, the first row of seats should be approximately 2
screen heights away.
· The bottom of the screen should be a minimum of 4 feet above
the audience floor, allowing those seated toward the rear of the
audience to see the screen. This may require additional screen
"drop" for ceiling hung screens.
· Sleect the appropriate format for your projection
application. Common formats are as follows
Common Applications and Aspect Ration Width/Height NTSC Video
1.33
PAL Video 1.33
Letter Box Video 1.85
HDTV Video 1.78
35MM Filmstrip 1.32
2x2 Standard 35MM Double-Frame Slides 1.50
· Choose the screen surface that hottest suits your projcetion and
viewing requirements. If the screen will be used for multiple
projection methods, choose the screen surface that meets the
requirements of the lesser performing projection method.
For
example, if using a slide projector and a video projector, choose
the screen surface for the video projector since its light
output is generally less than a slide projector.
