Description: Get great color in difficult lighting with the patent-pending ExpoDisc. Whether youÆre
shooting RAW or JPEG, simply read and set white balance with the ExpoDisc before
shooting and youÆll reduce or eliminate the need for post-capture color adjustments.
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 color 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 color, 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 color temperature
of light illuminating the subject.
The ExpoDisc (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.
The image on the left was shot with the Canon 20D's Auto WB setting. The image on the right was shot
using the same camera with an ExpoDisc custom white balance. How do I use the ExpoDisc? The ExpoDisc is far easier to use than any gray card, white card or calibration target.
Simply place the ExpoDisc in front of your lens and capture the incident light while setting
your cameraÆs custom white balance. Using an ExpoDisc custom white balance will virtually
eliminate the need for RAW or JPEG post-capture color adjustments.
ExpoDisc technology takes a unique approach to setting a custom white balance and
producing accurate color. The ExpoDisc essentially uses your cameraÆs built-in custom
white balance capability to turn the camera into an incident color-metering tool. By setting
white balance as an incident filter rather than as a reflective target, the ExpoDisc avoids the
common problems and inconveniences associated with using gray cards, white cards and
calibration targets: unwieldy size, unwanted reflectivity, improper angling and difficulty of
filling the frame.
Why is the ExpoDisc the best white balance tool available? ExpoDiscs are constructed of multiple layers of carefully selected optical grade materials
which are tested on a sophisticated transmission spectrophotometer. Each ExpoDisc is
individually tested to our strict tolerances of color neutrality and light transmission.
ExpoDiscs are assembled and tested in the U.S.A..
What size lenses does the ExpoDisc fit? Do I need to buy an ExpoDisc for all my lenses? The ExpoDisc works with any digital SLR and digital video camera with a white balance
function. ExpoDisc filters are available with quick pressure release friction mounts (in
standard sizes, including 52mm, 58mm, 62mm, 67mm, 72mm, 77mm, 82mm, 95mm, as
well as 4x5.65 Video Format Filters). If you have multiple lenses, you can start by
purchasing an ExpoDisc that fits your largest lens and the holding the ExpoDisc flush over
smaller lenses.
Does the ExpoDisc work for video applications? All ExpoDiscs work just as great for video applications as they do with still cameras. The
ExpoDisc excels as a video white balance tool, especially in situations where a videographer
needs to quickly set white balance while on the move. In addition to ExpoDisc round filters,
we also make an ExpoDisc Video Format Filter which is large enough to fit over many
video camera lenses and has a convenient grip-handle.
