IMAX, Carnival announce first theater on a ship

I-Max has adopted digital projection, using 2 projectors for light output. They have bet the store on the ( coming soon) laser illuminated digital projectors. In earlier years, Todd-AO 70mm was used on some European cruise ships.

The old I-Max used 70mm film 15 perforations wide, like VistaVision, the image goes sideways through the projector and camera.

There is no digital projection system in use that can equal a 70mm film print. Today, in the industry, we lovingly call digital I-Max, Lie-Max.

A 4k digital image is barely equal to 35mm and lacks 1/3 the resolution of anamorphic ( CinemaScope) film...most digital theaters are 2K.

When FotoKem works on large format restoration they scan at 8K and work from there, down converting as format requires.
