A new button-activated spring design enables ExpoDisc 2.0’s filter mount to be easily attached to lenses with 77mm filter diameters. For lenses with smaller filter diameters, the ExpoDisc 2.0 is simply held in front of the lens while setting white balance or

metering for exposure. The filter is precisely calibrated and includes two levels of custom warming gels which can be used to add warmth to portraits. It can also be used as an 18% incident exposure meter for measuring light entering the camera. This provides correct exposures, regardless of the subject.

ExpoDisc 2.0 can also be used to map dust on image sensors by recording an anchor image that can be used for batch correcting dust-affected image files. It is supplied with a comfortable lanyard and sturdy carrying pouch plus a calibration certificate and quick start guide. RRP is AU$69.95. For stockist information, visit
