Anamorphic Options
There is something really special about going to the movies to see the latest blockbuster films. Seeing the curtains open out to the wall to reveal the deluxe widescreen aspect ratio known as Cinemascope is quite the spectacle. Cinemascope format has been used by movie directors since the 1950's and movies the World over are being shot and displayed in this format. When watching such films on a TV you will notice black bars top and bottom. These are encoded into the film to keep the correct geometry, being a 16:9 ratio, also known as HDTV format. When using a projection setup in your home to watch such films, we can manipulate the image electronically and optically to re-create what is done at the cinema, with NO black bars at all!

By using an anamorphic lens, you can display the film in it's true aspect ratio, an image that is the same height as all HDTV formats but one third wider again, as per the cinemas. Directors choose this format no doubt for a variety of reasons, but for the viewer it's about the impact and immersive nature of the film. A native landscape image that is 33% wider than the traditional HDTV or 16:9 format. Watching films in Cinemascope format is simply unbeatable. This method is also referred to as CIH Projection or 'Constant Image Height' projection. This means all your films share the exact same height. Only the width of the image changes according to the aspect ratio. See images below to better understand how this all works.
How it works
A 16:9 Letterboxed image sitting within a 21:9 Cinemascope screen. Note where the format boundaries are. The active image is the HDTV format 16:9 with black bars included to make up the correct geometry. The white outer edge is the screen boundary of a cinemascope screen. Only 810 lines of active pixels are used here, the remainder of the projectors active pixels sit in the black bars.

Part 1 is the electronic scaling of the image with the projector. This is often called 'Stretch', 'Vertical Stretch' or 'Anamorphic mode'. If you're not sure if your Projector has this feature feel free to contact us to find out. You will usually find this feature somewhere on the projectors remote or in the menu on screen. (There are also DVD players such as the OPPO BD series that have this function built into them) We are now using the entire 1080P panel of the projector.

Part 2 is the use of the Anamorphic Lens (optical expansion). This stretches the light beam by 33% in the horiztonal plane only (a factor of 1.33) to restore the geometry on screen. The result is true Cinemascope with no black bars top or bottom. 78% larger than the original image.

Weapons Of Choice.....
There is quite a bit of talk out there about anamorphic lenses, since the introduction of motorised zooming projectors, (where you can store the zoomed setting and recall it for both 16:9 and 21:9 films) As long as the image is going to be bright enough, (often it's not), as long as the pixel gap (screen door effect) is not going to an issue, by all means, zoom away those black bars and enjoy your cinema. Some lens manufacturers make ridiculous claims like 30% more brightness. The truth is more like 10-20% and I say 20% with something like the CrystalMorphic 5E 4K Lens - I would NEVER put any other lens in front of a new projector, period, regardless of their 15-20K price tags and questionable claims. The CrystalMorphic lens is a brand new 21st Century Design. A step up in complexity over the traditional 4 element single air gap cylinder lenses (a design that has not changed since the 1950's!). It's the ONLY lens with tolerances high enough to resolve a 4K image with next to no abberations. It is truly the finest anamorphic lens ever produced.

The key benefits over the traditional 4 element cylinder lenses are even light illumination across the screen, sharper, less grid distortion and overall a more transparent image can be had. It's Australian made too, another Aussie World first!
