Answer:
One of the more recent developments in film are the advances in 3D filmmaking. 3D movies allow viewers to see a three-dimensional image with special glasses. This type of filmmaking has become very popular recently, though it was invented a long time ago and was also popular in the 1950s. It is only in recent times that it has become cost-effective. The quality technique is reliable and relatively cheap.3D films give the illusion of depth, thus enhancing a film’s experience. A 3D film is filmed using what is called stereoscopic photography. This technique uses two cameras at slightly different angles to capture an image from two perspectives. This can also be done in post-production. The viewer wears glasses that block out one of the images, such that each eye gets a slightly different image. This creates the illusion of depth.Some filmmakers have radically experimented with 3D technology. These include the French filmmaker Jean-Luc Godard, in his 2014 documentary Goodbye to Language. This film uses what are called “separation” shots, in which single shots are separated into each eye. In other words, one eye gets one continuous shot while the other eye gets another. This was a completely innovative approach to film technology.
