This approach is an economical way to keep the black bars of UltraWide movies off the screen by projecting them onto the walls above and below. Almost every high end home theater projector has this capability and yet every high end home theater projector also has the anamorphic modes for using an external Panamorph lens.
As quoted by you, when the throw ratio is nearer then there is Anamorphic projection of this pincushion. But, if Iam using the curved screen will this nullify and show a perfect picture? I had discussions with my acoustic consultant today and he was suggesting me a room size of 20ft L x 13 W x 12ft H and the back row seating from screen distance would be at 16ft leaving 4ft behind.
This helps accessing my equipment rack and also gives the surround speakers a more realistic feel when behind in straight line speakers facing each other parallel to the back row seat.
I checked with the Panasonic throw ratio calculator for 2. You are right about the Coming to the centre speaker placement thats a very nice suggestion. I know in that case I need to use a acoustic material screen fabric.
This would ultimately give a very good visual appeal. I don't know how much extra I need to shell out for the slide mechanism and thinking whether it can be custom made as a manual type. In one forum I saw a member using a Chinese make anamorphic lens.
Is it cheap, as well giving decent picture quality, would like to know if there are some You have Anamorphic projection see the images they can produce and decide if they are for you or not, along with the need for a corrector element. The further back the projector is, the smaller the amount of pincushion.
Ideally you need the pj at a throw of 2: For a 10ft 2. Mark uses a ratio to calculate the screen size based on the room size: Cinematic Audio Visual eXperience: If you want an image with a more cinematic reflectance level then most projectors should be able to provide that. A 10ft wide 2.
If you want something brighter or have 3D in mind then a smaller screen or one with more gain will be needed, along with other considerations with the install and pj placement.
The AE has a few different modes that allow more or less lumen output, but it depends on how accurate you want the image to look. Calibrated images tend to result in less light output.
Seating distance is very important IMHO. If you don't sit close enough, I think THXs recommendation of a 40 degree viewing angle for It's a seating distance equivalent to 2. It's not unlike sitting in the centre seats of a commercial THX theatre.
Of course not everyone likes sitting there some may prefer sitting closer, while others prefer further back. Some people don't even like their That set up doesn't necessarily need an A lens, just the zoom. Your suggested seating distance of 16 feet from lets say a 10 foot wide scope image is the equivalent of sitting in the back row, and It might be an idea to get the projector first and project onto a freshly painted white wall to see what screen size and seating distance works for you, and if CIH is you preferred set up.
You may even find that you like the zoomed scope image and don't necessarily need an A lens due to the Panasonics Smoothscreen technology. Do you want to have more than one row of seats? I would suggest the front row be at something like 2.
You need seats to be at least 4 feet away from any speakers so it may affect how many seats you have in each row. The ideal is no bad seats.
Of course if you want to fit more people in, then some seats will have to go closer. It's a compromise but at least more people get to watch. If you have tiered seating make sure the front row doesn't obscure the centre speaker if it's under the screen as it will mute the audio for the rows behind.
Having the speaker above may work better in some instances. There are a few dealers here in the UK many on this forum who can get you an A lens, but the spherical lenses tend to be quite expensive when bought new - much more than the pj in some cases.That’s an anamorphic illusion, a projection art technique also known as perspective anamorphosis.
It’s been around since the 15th century but is enjoying a recent revival in . Anamorphosis is a distorted projection or perspective requiring the viewer to use special devices or occupy a specific vantage point (or both) to reconstitute the image. The word "anamorphosis" is derived from the Greek prefix ana‑, meaning "back" or "again", and the word morphe, meaning "shape" or "form".
After some research, I found that other DIY filmmakers are re-purposing old film projection lens, typically used in movie theaters, to “correct” the compressed anamorphic image into what we. An anamorphic projection system lets you watch even HDTV content in the UltraWide format. 3. You can now watch ALL today’s content with maximum performance to fill your screen % of the time with no black areas at all.
By affixing an anamorphic lens to the projector in front of its normal lens, the image is optically undistorted as it passes through the anamorphic lens, so it .
Applying an anamorphic lens to the vertically stretched image stretches it horizontally to restore it to and perfect geometry for a CinemaScope widescreen. However, there’s another way to go about viewing CinemaScope movies on a screen: Use an anamorphic lens mounted to the front of the projector.
