Low level 3-D movie brightness combated by laser projection
A ground-breaking laser light film screening has taken place in London, heralding a new dawn for 3-D films.
3-D films are traditionally rather dimly lit, but this new laser light technology could match the existing brightness levels found in 2-D films.
The feature film - Martin Scorsese’s Oscar winning Hugo – was the first film to be shown in its entirety using laser technology. The laser light technology helps to combat the low level light currently produced by some projectors during 3-D films.
Viewers at the screening, which was held at the IBC at the International Press Centre in Shoe Lane, London - first saw Hugo – alongside clips from Puss N’ Boots and Transformers: Dark of the Moon – at a light quality of 3 foot-Lamberts. This level of light is what most 3-D films are currently shown in.
The viewers also watched the films at 14 foot-Lamberts thanks to the laser light technology. This is the level of light in which most 2-D films are currently shown to cinema audiences.
Christie, the projector manufacturer, was behind the screening and the senior director of product management at the firm, Dr. Don Shaw, told 3D Focus, “Some attendees leave 3D movies complaining of headaches, fatigue, and sore eyes.
"Just like reading a book in low light levels, low brightness on the movie screen is one of the reasons for these complaints. Delivering more lumens to the screen will help address these effects, as will the advent of ‘eye-easy’ high frame rate (HFR) movies," he went on to say.
