ExpoDisc 2.0 Makes Custom White Balance a Snap
|
Press release
ExpoImaging, Inc., designers of innovative camera accessories for the photographic market, today introduced the patented ExpoDisc 2.0 Professional White Balance Filter, an incident light metering filter for digital cameras, for both still and video applications.
“With the original ExpoDisc, we invented the digital white balance filter and established it in the market as the premium white balance tool by individually testing and certifying every ExpoDisc,” said Erik Sowder, ExpoImaging CEO. “Now, ExpoDisc 2.0 introduces user-selectable warming gels, an improved mounting design, and a new lower price-point.”
Whether shooting in RAW or JPEG, photographers using ExpoDisc 2.0 to white balance their images save valuable time during the photo editing process.
Beyond its primary function as a white balance tool, the precision calibration and uniformity of the ExpoDisc 2.0 means that it can also be used to meter for an 18% incident exposure and to dust map the image sensor. Made in the USA, every ExpoDisc 2.0 is tested by hand on a transmission spectrophotometer and individually adjusted using custom filters to ensure neutrality and an 18% total light transmission across the visible spectrum. This neutrality is important because using a non-neutral tool for white balance can actually add undesirable color casts to images.
The original ExpoDisc Professional White Balance Filter was available in separate Neutral and Portrait (warming) versions. ExpoDisc 2.0 combines these versions into a single tool. ExpoDisc 2.0 includes two levels of custom warming gels which can be inserted into recesses on the face of the ExpoDisc, enabling photographers to add varying degrees of warmth for pleasing skin tones.
The ExpoDisc 2.0’s new filter mount design attaches securely to lenses and even to low-profile threaded lens filters.
The ExpoDisc 2.0 will initially be available in a 77mm filter size with more sizes to follow. As with the original ExpoDisc, a larger ExpoDisc 2.0 can be used with smaller filter size lenses by simply holding the ExpoDisc 2.0 over the lens during the white balance procedure.
Pricing and Availability
ExpoDisc 2.0 is available now through ExpoImaging’s distribution partners worldwide, or online at https://www.expoimaging.com. The ExpoDisc 2.0 77mm White Balance Filter retails for $49.95.
