Quickstart Guide
Save Time Editing Photos and Video:
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 cameras custom white balance. Using an ExpoDisc custom white balance will virtually eliminate the need for RAW or JPEG post-capture color adjustments. Whether shooting in RAW or JPEG, photographers using ExpoDisc to white balance their images save valuable time in photo editing software. 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.
ExpoDisc Is Designed, Assembled, and Hand Calibrated in the USA:
Every ExpoDisc is tested by hand on a transmission spectrophotometer and adjusted using custom formulated materials to ensure an 18% light transmission across the visible spectrum. Each ExpoDisc includes a quality control card to certify its neutrality as tested on our spectrophotometer.The neutrality of a white balance tool is important because using a non-neutral device alters the color of light against which your camera applies its adjustment, in the process introducing a new color cast to your images.
77mm and 82mm ExpoDiscs Can Be Used with Smaller Lenses. Larger size 77mm and 82mm ExpoDiscs can be used on cameras with smaller filter size lenses. Simply hold the ExpoDisc over the lens during the white balance procedure to capture the reference gray frame.
ExpoDisc Attaches Securely to Lenses and Threaded Filters:
The ExpoDisc filter mount features a spring loaded design which allows the ExpoDisc to securely attach to equivalent sized lens filter threads, including most low-profile threaded lens filters.
How Do I Set a Custom White Balance with the ExpoDisc?
To set a custom white balance with the ExpoDisc, simply place the disc in front of your lens and capture an incident lighting reading through it while following your cameras custom white balance procedure. For most cameras, this procedure takes only 10-15 seconds. Thats it. No special software, and no post processing required. If youre shooting JPEG youre done. And if youre shooting RAW, simply download your images as shot to save yourself valuable time correcting color.
How does the ExpoDisc work?
Your cameras internal light meter measures the color temperature of light passing through the ExpoDisc to make an in-camera color adjustment. This color adjustment is applied to all subsequent images taken using the custom white balance from the selected light reading. Or, if you prefer shooting in RAW file format and batch processing later, simply capture a reference image through the ExpoDisc to use with your image processing software.
Meter for 18% Incident Exposure with the ExpoDisc:
The ExpoDisc is not just for white balance, though. 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 subjects position and aim the camera back towards the intended shooting position. Use the cameras meter as seen through the viewfinder to adjust the aperture, shutter speed, or ISO until a proper exposure is indicated. Its also possible to make exposure adjustments based upon the position of the cameras histogram spike on an ExpoDisc test shot. Simply adjust the aperture, shutter speed, or ISO until the spike is centered.
Dust Map Your Image Sensor with the ExpoDisc:
Quickly check your camera sensor for dust, or create a dust map to use later in image editing software. Attach the ExpoDisc to your camera lens, place the camera in Aperture Priority mode, then set the Aperture to f/16. Set the lens in manual focus mode, and set the zoom to 50mm or longer. Aim the camera towards the brightest available light source and click the cameras shutter to capture your dust reference image. Sensor dust can be easily identified as spots on the resulting gray image.
Will the ExpoDisc Work with My Camera?
The ExpoDisc can be used with any digital camera with a custom white balance capability, including all digital SLRs and most point & shoot cameras. The ExpoDisc works with all major camera brands, including: Canon, Nikon, Sony, Pentax, Olympus, Samsung, Lumix, and Leica.
Why ExpoDisc?
We Individually Calibrate Each ExpoDisc for Neutrality:
Only a truly neutral white balance tool like the ExpoDisc will produce consistently accurate color balance in your images. Every ExpoDisc is assembled and calibrated in the USA using custom filters to make sure it transmits light evenly across the visible spectrum. Other tools may claim to be neutral, but do they actually take the time to ensure their accuracy?
ExpoDisc Gives Consistently Great White Balance in Only 10-15 Seconds
No special software and no post processing is required.
Smaller and easier to use than gray cards and targets, ExpoDisc fits in a shirt pocket and only requires you to cover the lens to set a custom white balance. This is usually much quicker than placing a gray card or target in your scene and then taking a reflective reading at a distance.
Custom White Balance Gives You Consistently Great Color
Even the best digital cameras struggle with consistently reproducing accurate color. Images shot with incorrect white balance may have unnatural looking red, yellow or blue tints that are time consuming and difficult to correct.
To help photographers cope with this problem, digital camera manufacturers designed their cameras with multiple white balance functions, including Custom White Balance, Automatic White Balance (AWB), and factory Preset color temperature settings.
Unfortunately, Auto White Balance (AWB) often produces inconsistent color results, and the color temperatures assigned to the cameras Preset white balance settings often do not reflect real world lighting conditions.
Using your cameras Custom White Balance function remains the most reliable way to consistently reproduce accurate, balanced color in digital cameras. The custom white balance function eliminates the inconsistencies of AWB and the gross generality of factory Preset color temperatures because it allows the user to calibrate the camera to an exact color temperature at image capture.
