Outstanding work, sir. I love watching Cinerama-format films. Such a wonderful age, blending the art of cinematography with the science of state-of-the-art projection. I think people attending films really got their money's worth back then, more so than we do now.
Thanks for your comment. Unfortunately, today we are bombarded with 24hr multi channel TV. Not much hope for the old fashion Cinemas. With my set up, I can enjoy movies as they should be seen.
Can't beat good old experience, not enough of that about today, very interesting video Dave, I've been looking at a curved screen for a future project, but warp programs / running a pc put me off, you've put a lot of work into these several minutes, well done, I wish TH-cam had more video makers like yourself, best regards
@@davesdigitalmovies thankyou for replying Dave, I appreciate that, I'll subscribe and will check out your other videos for sure, kindest regards Sir 👍
Thanks Dave great explanation. My flat screen at the moment is Carl’s screen vinyl stretched to an aluminium frame. I’m going to try a minimum curved screen using similar materials.
Great video Dave. I’m thinking of turning a circular living room into a cinema room. Would a laser projector be able to project directly onto the curved wall I wonder?
I can not see any reason why not. Provided the curve is not too deep, the focus should be ok. Don't forget about centre sag with a high projection angle. This will be a big problem if the curve is too deep. Have a look at my Cinerama video, this may help.
I love Cinerama, I have seen almost all Cinerama films at the Paris Cinerama theater in their time, and I have all the blu-ray releases of Cinerama film. But my 55" flat screen TV is far to small to reproduce the Cinerama effect. I am looking forward to use a projector and built a large deeply curved screen, may be not as much as the 146° Cinerama screen, but at least 120°. But I fear there will be a focus problem with the projector. How can it be solved ?
If you construct your screen curved to the arc of the projector beam, you will not have focus problems. Be aware, if you are projecting downwards from a high angle onto a deeply curved screen, the problem will be centre sag, although with the smile box format, this is not so noticeable as a straight frame line. Good luck with your plans. Dave
I am looking at trying to do the same thing because the resulting picture is as close to the cinema experience you can get. Can I ask how close to the lens do you position your apertures?
The mask aperture is 23 inches ( 585mm ) in front of the lens. This is about as far as you can go before it all gets to head height. If the mask is too close to the lens, you get a very fuzzy 'frame line'. Good luck with your project.
Until you have seen a movie in TRUE Cinerama you haven't seen a movie. I wish it would come back. Until then my home curved screen will do. Great video sir!
I have seen all real Cinerama 3 strips films (but the Brothers Grimm) and the first two Kinopanorama films in Paris. It was far more immersive than Imax (I have seen all kinds of Imax 70mm films, 2D and 3D, dome or flat screen at the Futuroscope in France). Now that most cinerama films are available on blu ray, I have been thinking of building a ¨home Cinerama". My problem is not about building a 146° curved screen, it's about how to get a proper focus on all of the screen...
@@78Dipar I do have seen all the 3strip Cinerama movies..many times over when they played in Toronto.The only one that really looked great (not Cinerama) but projected onto a Cinerama screen was 2001 which played at the Glendale Cinerama in Toronto for almost 3 years. My screen was just curved dry wall (not a huge curve) 12feet wide and when a Cinerama bluray was projected on to it ..Great! I should have said the only Non Cinerama 3strip movie that looked good was 2001 but still not as good as true Cinerama.Cheers from Canada!
@@robertgraziano The Cinerama immersive effect works only when filmed at 146° and projected at the same angle on a deeply curved screen. I have seen "2001" (filmed in 70mm Super Panavision) and "The fall of the Roman Empire" (filmed in 70mm Ultra Panavision), both on a real Cinerama screen, but the immersive effect wasn't there anymore because the shooting angle wasn't wide enough, both with Super and Ultra Panavision. This is what killed Cinerama...
My cinema room was a garage, with recycled materials I have created this over the course of around 10 years. Adding bits an pieces along the way, it started with a 42 inch TV and an old 2 channel amp & speakers. Lots of work and time, but well worth it !
@@davesdigitalmovies I've watched your other video where you put the hardboard screen up, did it already have a reflective coating? One of the highlights of recent years was watching Around the World... at Pictureville in Bradford, I hadn't realised that Cinerama came with surround sound! I saw Close Encounters in surround sound when it first came out, and I thought surround sound was a new thing... but no! I couldn't believe my ears when a brass band marched across the screen and the sound moved left to right and front to back!
@@deeby001 The hardboard screen is painted with matt white emulsion, using a roller. This works fine in a blacked out room with black masking around the picture area, the only way to watch a movie... As for the surround sound, Walt Disney used a separate 35mm 4 track optical sound in 1940 for the animated film, 'Fantasia'. Before my time by three years, but I did see a Cinemascope 4 track mag version in the mid fifties. I did show a scope version of 'Around the World' back in 1959 when I was a trainee projectionist.
The side masking (vertical) just bolts to the side support frame on the Cinerama screen. It's just the top & bottom that is changed for Todd-AO.. . On the CinemaScope screen, the side masking (hardboard covered with black material) hangs on a wood track. Professional masking runs on a short straight tab track, on a 40' screen the masking would only cover about 5' 6". = 2.40 masked to 1.85. I hope this makes sense, maybe another video?????
For a monitor that size, you would need to sit very close to get any effect from a curved screen. Distorted reflections from lighting and windows can be distracting on very dark scenes. Personally, I am happy with a 42" flat screen TV . Film nights are always in the cinema. A projected picture is more immersive on a curved screen, but it will not make a poor film any better. I hope this helps you to make a decision. Dave
I would love to watch movies in CURVED SCREEN rather than a FLAT SCREEN ....Thanks for the video....hope you will do one detailed video about how to project regular movies in CURVED screen? Waiting for that LOVE FROM INDIA
@@arunvalsan1907 Any movie filmed for the scope or widescreen ratio can be projected onto the curved screen, the only problem you will have is 'centre sag'. This can be masked at the projector, to match the screen masking. Have another look at the video, and good luck with your curved screen adventure!
@@davesdigitalmovies Thanks for your reply @ This day sir This day is auspicious festival day in INDIA named ONAM..... My HEARTY ONAM GREETINGS TO YOU Have a good day
Just trying to find someone who can tell me what the curved screen is like for movies better or worse than flat. Frustrating trying to get a video about this. I don't have a projector. Wouldn't want one either.
The curved screen makes no difference to a movie on TV. For films, I prefer a projected image, it gives more of a cinema feel. The curved screen enhances the cinema experience, but does not make the movie any better.
Any projector can be used with a curved screen, provided the curvature is not to deep. A few inches to create the curve is all that is needed. It enhances the look and draws you into the picture. To much curve and centre sag becomes a problem. Dave
@@davesdigitalmovies It's sad that the new generation is content to watch movies on their tiny devices and not experience movies the way they should be seen and heard.Toronto had three great Cinerama theatres that are all gone now. Sad!
If you ever experience a true Cinerama movie you would change your mind. I remember seeing 2001 being shown on a huge Cinerama screen and the opening scene felt like the whole theatre was floating in space....AWESOME!

Curve screen doesn't work for me. I prefer flat screen.

Just....NO.
Black bars top & bottom.... your choice!
