ExpoDisc Saves Time Editing White Balance in Photos and Video
When used to set a custom white balance, the ExpoDisc consistently produces excellent color in natural, artificial, and studio lighting, and it even excels in difficult mixed lighting environments. Easier to use than a gray card, white card or calibration target, simply place the ExpoDisc in front of your lens and capture the incident light while setting your camera’s custom white balance. For most cameras, this procedure takes only about 15 seconds. Whether shooting in RAW or JPEG, using the ExpoDisc to white balance your camera saves valuable time in photo editing software.
Meter for 18% Incident Exposure with the ExpoDisc
The ExpoDisc is not just for white balance. The precision calibration and uniformity of the ExpoDisc means that it can also be used to meter for an 18% incident exposure. To meter for an 18% exposure, stand at the subject's position and aim the camera back towards the intended shooting position. Use the camera's meter as seen through the viewfinder to adjust the aperture, shutter speed, or ISO until a proper exposure is indicated. It's also possible to make exposure adjustments based upon the position of the histogram spike on an ExpoDisc test shot. Simply adjust the aperture, shutter speed, or ISO until the spike is centered.
ExpoDisc 2.0 Includes New Portrait Warming Filters (Gels)
ExpoDisc 2.0 includes two levels of custom warming filters (gels) which can be inserted into recesses on the face of the ExpoDisc, allowing photographers to add varying degrees of warmth for pleasing skin tones. Under daylight balanced studio lights, the +1 and +2 custom Warming Filters provide 250˚ and 400˚ Kelvin warming, respectively.
Larger ExpoDisc Sizes Can Be Used with Smaller Lenses. New Design Attaches Securely to Lenses and Threaded Filters.
The ExpoDisc 2.0 will initially be available in a 77 mm filter size with more sizes to follow. The ExpoDisc 2.0’s filter mount utilizes a new button-activated spring design which allows the ExpoDisc to securely attach to lenses and threaded lens filters. As with the original ExpoDisc, a larger ExpoDisc can be used with smaller lenses by simply holding the ExpoDisc over the lens to set white balance or meter for exposure.
Every ExpoDisc is tested and certified on a spectrophotometer for neutrality and 18% transmission.
ExpoDisc Is Hand Calibrated and Assembled in the USA
Made in the USA, every ExpoDisc is tested by hand on a transmission spectrophotometer and individually adjusted using custom formulated materials to ensure an 18% total light transmission across the visible spectrum. Each ExpoDisc 2.0 includes a quality control card to certify its neutrality as tested on our spectrophotometer. This neutrality is important because using a non-neutral tool for white balance can add undesirable color casts to images.
