It fits over a wide variety of larger video (and still) lenses and provides a fast and easy custom white balance solution for videographers, and turns what has been a difficult colour management problem into a simple routine. Simply read and set white balance with the ExpoDisc in place to consolidate several on location and post processing steps into one quick and easy custom white balance procedure. Get the same consistent, accurate colour without the need to worry about the accuracy of the camera's own auto white balance (AWB), or fumble with cumbersome cards and targets. Each ExpoDisc is manufactured and individually hand calibrated to fall within strict tolerances of light transmission and colour neutrality. Consisting of multiple layers of carefully selected materials, the ExpoDisc is guaranteed to be within +/- 2% of neutral for demanding professionals. More
What is white balance, and why do I need to set a custom white balance with an ExpoDisc?
Even the best digital cameras are incapable of consistently delivering accurate colour without the user performing a custom white balance. Auto (AWB) and preset white balance functions often produce maddeningly inconsistent results. Images shot without a correct white balance may have unnatural looking red, yellow or blue tints that are time consuming and difficult, if not impossible to correct.
Recognizing the importance of custom white balance to good colour, digital camera manufacturers have designed their cameras to take advantage of a custom white balance. A custom white balance calibrates the camera to the exact colour temperature of light illuminating the subject.
The ExpoDisc Professional Digital White Balance Filter (patent pending) is a custom white balance filter that allows digital photographers to quickly and easily set an accurate custom white balance. Consistently producing excellent results in natural, artificial, and studio lighting, the versatile ExpoDisc even excels in difficult mixed lighting environments.
