Types of Technology Used in Rear Projection
Have you ever wondered how moviemakers film intense car chase scenes without the
camera shaking too much? Sorry to ruin the movie magic for you, but most of the time,
those sequences aren’t entirely “real.”
So how do they do it? Your first guess is probably that they use a green screen,and that’s
true, for most of the part. But during those days when green screen technology wasn’t yet
as well-polished as it is today, filmmakers relied on another technique: Rear Projection.
Modern classics such as Pulp Fiction, Terminator 2, and Aliens all had their fair share of rear
projection. It was the most innovative way to shoot action-packed scenes without spending
money on an actual set.
Rear projection or process photography involves using a still or moving picture projected
onto the back of a translucent screen. This gives the illusion of a real-life background while
people are moving in front, as if they were occurring at the same time.
The technology involved in process photography consists of the following: A projector, a
screen, and a camera. Some studios might need a sound stage and a large open space,
depending on what’s being shot. Essentially, the projector is placed behind the screen to
cast a reversed image, also known as the plate.
Process photography has slowly been declining due to its expensivebudget. It’s been
replaced with newer techniques such as front projection and blue screen effects; however,
this doesn’t mean that rear projection is entirely obsolete.
In fact, the technique is still widely used, just not in the film industry. Instead, you can find
it in advertising. Try visiting a mall, showroom, or an airport. You’ll probably see a digital
signage that uses rear projection films.
The great thing about these projection films is that they have a wide range of applications.
Aside from digital sign ages, you can use them for front store window advertising and
marketing campaigns. They’re made of the latest optical technology, with just enough
brightness, contrast, and black levels to catch anyone’s attention!
How can you find high-quality projection films? Consider factors such as installation, design,
and price to ensure that you get the most out of your marketing budget. Some providers
even offer self-adhesive films that can stick to windows easily with some water and
detergent.
