DSC NorthernLights Extends Colour Tests for Digital Cinema

DSC NorthernLights Extends Colour Tests for Digital Cinema: "DSC Labs has designed NorthernLights, a new test target to help optimize image quality in
digital cinema and HD television, overcoming narrow colour gamut limitations.

Named after the Aurora Borealis light display, NorthernLights provides test elements that function well outside the Rec 709 colour space, which is useful for people working with digital cinema and other high-end camera systems. 'Camera and sensor systems have evolved beyond the level of colour saturation that can be reproduced in typical test charts,' said DSC Labs President, David Corley. “NorthernLights combines a front-lit system with self-illuminated high gamut colours, giving camera users a way to calibrate and test their cameras in colour space beyond conventional front and rear-lit techniques.' NorthernLights has front-lit 24 DSC-calibrated colour chips for accurate reference and setup to the Rec. 709 standard. It uses an 11-step spectrophotometrically neutral crossed grayscale for gamma adjustment, and horizontal/vertical hyperbolic wedges, or DSC trumpets, to test camera resolution. Upper and lower 18% gray strips check evenness of lighting, both horizontally and vertically, and controls adjust brightness and colour to balance white levels. NorthernLights will be on display at NAB 2011. www.dsclabs.com
