Winner of the 2014 Professional Photographer Hot One Award for Best Product in the Color Management System Category.


  • SAVE TIME FIXING COLOR – set a custom white balance to get beautiful color straight from your camera – stop wasting time fixing your color later with software
  • EASY TO USE – the ExpoDisc is easier to use than white balance cards, gray cards, and photographic calibration targets – simply attach the ExpoDisc to your lens and set your camera’s custom white balance
  • QUICKLY SET WHITE BALANCE – just attach the ExpoDisc to your camera’s lens and follow a few simple steps to set the white balance – in most cameras you can set a custom white balance in just 15 – 20 seconds
  • METER FOR 18% EXPOSURE – ExpoDiscs are individually calibrated to transmit 18% light – this produces a gray frame reference that can be used instead of a photographic gray card to establish an 18% exposure
  • MADE IN USA – we care about our products – we assemble, calibrate, and certify every ExpoDisc in California – 1 year warranty
