Harkness Screens will offer a free web seminar on Feb. 29 on the
subject of 3D and screen selection.
The large number of cinemas that are now showing 3D movies has made
screen brightness levels an important topic. Because of the low
light efficiency of all 3D systems (some are better than others,
but all lose a lot of light) the de facto screen brightness
standard for 3D presentations is 4.5 foot Lamberts (fL) ,which is
only one-third of the agreed standard for 2D of 14fL.
In practice, many 3D screens are operating with much less than
4.5fL and the choice of screen is a significant factor in this.
However, it is not just 3D where correct light levels are
important—Harkness says there are many cinemas operating in 2D with
light levels below 14fL, and a factor here is the higher operating
costs of digital projection compared with 35mm film projection.
Screen selection is an important consideration in achieving the
14fL brightness standard in 2D presentation.
Harkness’ web seminar will cover the methods for achieving the
correct brightness levels for 2D and 3D cinema; the importance of
screen selection in achieving desired light levels; how screen
choice can optimize operating costs; and how to measure screen
brightness.
