Dynamic Gain Lens

The Problem

All cameras suffer from image loss due to the limits of their dynamic range. No amount of post production can retrieve this detail when lost at the time of capture.

The Technology

The LiveLens dynamic gain lens is a high definition retro fittable contrast compression system that expands the dynamic range of the host camera and lens systems by over 4 aperture stops.

The device responds to incident light striking the photo active surface within, instantaeously forming a neutral density reduction of light according to the amount of light falling on it. The effect is an active neutral density masking of the brighter regions of a scene, thus reducing the contrast between brightest and darkest extremities of a scene and enabling a greatly enhanced capacity for detail capture in bright conditions.

The LiveLens dynamic gain lens may remain permanently fitted to the host camera system providing a fundamental new controlable optical gain functionality. Our goal is to provide contrast sensitivity characteristics for cine camera systems that closely resemble the way our eyes perceive a scene.
