LONDON—At the Empire cinema in Leicester Square this morning, IMAX unveiled Europe’s first “IMAX with laser” digital projection system. As the name implies, the main difference is that laser-based IMAX uses a laser light source rather than a stupendously powerful (15kW) xenon arc lamp. This results in a brighter, sharper picture, along with a wider colour gamut and blacker blacks. The first film to be projected via lasers will be The Walk, starting tomorrow. Perhaps more excitingly, both the upcoming Bond film Spectre and Star Wars: The Force Awakens will be shown on the IMAX with laser screen at the Empire cinema.
