How to get the IMAX Experience feel to your films.

I have always been a huge fan of seeing films in IMAX, especially when they are shot with IMAX cameras. I would like to get the IMAX look to my film as if I had shot it in IMAX. all the standard scenes will be shot in 1080p in a 2.40:1 aspect ratio. Select sequences will get the IMAX look to it such as higher resolution footage and an expanded aspect ratio. Any suggestions on how I would accomplish this such as shooring with different camera for each format? Thanks for the help.


Nothing truly has the imax feel short of imax itself. Its significantly higher resolution and the 70mm sensor is what really gives that felling, shoot 6k dragon will in theory blow up to the 70mm film size it doesn't have the same feeling. I would focus more on the story and visual story telling then trying to get the imax feeling, if it was something you could accomplish easy everyone would be doing it.

For your 2.40:1 stuff you could look into getting an anamorphic adaptor of some kind to give you approximated lens distortion and edge softening with realistic flares to help sell the anamorphic look.

I've actually thought of something like this. You could try doing something with speedboosters and 4k. It would give a similar effect as what IMAX has to where the depth of field gets shallower and the resolution goes up. For example shoot most normal scenes with the fs700 but for your psuedo-imax scenes put a speedbooster to make it fullframe and use an external recorder to record in 4K. To make the effect more dramatic you would need to record the 1080p scenes with a camera with an even smaller sensor, like the blackmagic pocket camera. I think that's the basis of it, smaller format going to a larger format, or at least the illusion of a larger format.

If you put a BMPCC Speedbooster on a GH4 (it's a tight fit, but it does fit) then the crop factor goes from 2x to about 1.16x when you shoot 1080p, and about 1.39x when you shoot 4K. It definitely doesn't match up to the 70mm IMAX format (but let's be honest, nothing does) but being able to shoot 4K closer to full frame than super35 is pretty nifty. Throw some fast lenses on there and you'll get some pretty epic shallow dof.

With that setup shooting 4K with a 24mm f1.4 lens will give you the full frame equivalent of a roughly 35mm f0.95.

Your best bet would be the Pentax 645z the only camera today using a medium format sensor to capture 1080p. It would require major color processing in my opinion though.

Another alternative is working on a view camera and then using various glass to focus it on a BMCC sensor. Here's more information on someone who's done it :

I don't think there is any cheap way of simulating the IMAX look which is super wide perceptual field-of-visual-view film-making with insane amounts of detail.

I think the only way to approximate this would be to mount 4 or 6 cameras all sync'd together so they would cover the field of view an IMAX camera would and be able to record the super high detail. This would be an editing nightmare in post... :-)
