## Description

Product Description          The ExpoDisc white balance filter allows digital photographers to quickly and easily set an accurate custom white balance. Each ExpoDisc is individually assembled, calibrated and certified for neutrality in the visible spectrum, and for 18% light transmission. The ExpoDisc can be used on-the-fly to set a white balance in-camera when shooting JPEG, or later in post production when shooting RAW. Using an ExpoDisc to set a custom white balance results in consistently balanced color and eliminates many of the yellow, red and blue color casts commonly seen in digital photography. The ExpoDisc is easy to use. Setting a white balance with the ExpoDisc eliminates many of the inconsistencies and inconveniences associated with using white balance cards and targets, including unwieldy size, unwanted reflectivity, improper angling, and shadows. To set a white balance with an ExpoDisc, simply take a photograph of the light source (incident light) through the ExpoDisc, then follow your camera's instructions to set the camera's custom white balance. Because the ExpoDisc is calibrated for an 18% light transmission, you can also use it as a reference tool for manually determining proper exposure. The ExpoDisc is available in a variety of sizes to fit most popular lenses. The ExpoDisc does not thread into the lens; instead, its quick mount design can be pushed-on and popped-off to facilitate a quick white balance.             From the Manufacturer          ExpoDisc Professional Custom White Balance Filter The ExpoDisc easily mounts to your camera's lens by pressure mount or can be held over smaller lenses.

Images copyright Zach and Jody Gray. Why should I white balance with an ExpoDisc? Because it saves time. The ExpoDisc White Balance Filter can be used to quickly set a custom white balance, virtually eliminating the need for RAW and JPEG color adjustments.  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. How does the ExpoDisc work? Your camera’s 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 applied from the selected light reading.  Or, if you prefer shooting in RAW and batch processing later, simply capture a reference image through the ExpoDisc to use later with your image processing software. How is the ExpoDisc different from other white balance tools? The ExpoDisc is more accurate than other white balance tools because it is hand calibrated and certified for an 18% light transmission across the visible spectrum. We individually adjust each ExpoDisc using multiple custom filters to correct for any variation in base materials. This precision ensures that your camera applies the correct color adjustments when setting a custom white balance.  Using an ExpoDisc is also easier than using unwieldy exposure targets and gray cards, awkward tools that often require an extra set of hands to hold and position properly. To use an ExpoDisc, simply attach it to the end of your lens before setting a custom white balance or metering for exposure.  ExpoDisc representative Lab values: L*=49.40,a*=.-.06, b*.04, Z%=17.90 These representative Lab values were produced by measuring light passing through an ExpoDisc using a transmission spectrophotometer. Why is it important to use a spectrally neutral white balance tool? Only tools that reflect or transmit light evenly across the visible spectrum can be trusted to work properly in a variety of shooting environments.  As the inventors of the Custom White Balance Filter, we have always gone to great lengths to ensure the neutrality of every ExpoDisc. Any non-neutral white balance tool will introduce color casts to resulting images because the tool itself changes the color of light against which the camera applies the color correction. How are ExpoDiscs constructed? ExpoDiscs are made from multiple layers of custom formulated materials contained within a high grade anodized aluminum filter ring. Each ExpoDisc's filter combination is adjusted by hand to achieve its neutrality. To ensure that every ExpoDisc is neutral, we measure and calibrate each ExpoDisc at our California facility for 18% light transmission and neutrality across the visible spectrum (400nm to 700nm). This 18% light transmission is ideal for setting a custom white balance, as well as metering for incident exposures in ambient light. 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.

To set a custom white balance with the ExpoDisc, simply place the disc in front of your lens and follow your camera’s custom white balance procedure to capture an incident light reading through it. For most cameras, this procedure takes about 15 seconds. That’s it. If you’re shooting JPEG you’re done. And if you’re shooting RAW, simply download your images as shot and save yourself valuable time correcting color. No special software, and no post processing required. Does the ExpoDisc work for video applications? Yes, the ExpoDisc can be used to quickly white balance any digital video camera with a custom white balance function. White balancing your video camera with an ExpoDisc will save valuable time in the editing room adjusting for color casts and inconsistent color. How does the ExpoDisc attach to my lens? The ExpoDisc was designed to make white balancing your camera easy. To help accomplish this, the ExpoDisc quickly attaches to the lens using an innovative friction mount design. When gently pushed into a threaded lens or filter, three small spring loaded ball bearings located around the filter ring slide over the lens threads to hold the filter in position until removed. Do I need to buy an ExpoDisc for all my lenses? No, if you have multiple lenses you can purchase an ExpoDisc to fit your largest lens. When using smaller lenses, simply hold your larger ExpoDisc flush over the end of the smaller lens. What ExpoDisc filter sizes are available?  ExpoDisc Professional Custom White Balance Filters are available in standard filter sizes, including 52mm, 58mm, 62mm, 67mm, 72mm, 77mm, 82mm, as well as 4x5.65 Video Format Filters.  Every ExpoDisc is individually hand calibrated, tested and certified in U.S.A.

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 have designed their cameras with multiple white balance functions, including Custom White Balance, Automatic White Balance (AWB), and factory Preset color temperature settings for Sun, Shade, Tungsten, Fluorescent, Flash, and Cloudy. When shooting, photographers must select one of the camera's fixed white balance settings to apply in-camera, or to apply later in post processing if using the RAW file format.  Unfortunately, Auto White Balance (AWB) often produces maddeningly inconsistent color results, and the color temperatures assigned to the camera's Preset white balance settings often do not reflect real world lighting conditions, causing a color-cast.  Using the 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. The custom white balance procedure requires a neutral reference like the ExpoDisc to measure the color of light accurately.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Simple and effective
*by B***N on March 11, 2012*

I wrote a glowing review of the Whibal card not long ago, and while I still use and really like that item, I also enjoy using my Expodisc. When I'm not using flash, it's quicker and easier than my whibal because I simply put the disc over my lens, point to the light source and shoot. I've found both the Expodisc and Whibal to be excellent white balance tools.An added benefit, for me, is using this as it was originally marketed, which is a basic incident exposure device. After using it this way, I must say I'm impressed with how much more accurate my exposure's come out as opposed to relying on the reflective metering and histogram reading inside my camera. I'm sure more sophisticated (and expensive) meters would be even more accurate, with better functionality, but for me, I'm thrilled not having to spend as much time in Lightroom trying to fix the arguments my camera has with the software program as to which exposure reading is correct. Of course, I try and stay out of it, but usually side with Lightroom, as it has a monitor to prove its point.....Luckily the ED has done a good job of helping them kiss and make up.This doesn't mean I still don't take some bad shots....I absolutely make errors (especially with flash) that make my camera and computer team up on me where I have to sleep on the couch. However, I'm a happier guy these days with better white balance and exposure from the get go.If you're needing an excellent white balance product that you can use everywhere and won't cost you a lot of money, but you want something with a bit more research and engineering behind it than a napkin, then the Whibal card is hard to beat. As I said, I love it and use it when I'm taking studio shots and also when I'm using flash.If you're needing an excellent white balance device that's a bit handier to use when you're on the go, I've found the Expodisc to be great. I know, I can't carry the Expodisc in my wallet like I can a Whibal card, but I also can't carry my camera in my wallet either, so usually when I have my camera, I've got the ED handy via lanyard. As I've already noted, getting an incident exposure reading is nice too. Especially when you're trying to take photos under multiple light sources, with natural light not being one of them. After trying a recommended Pringles lid, I'm glad I opted for the Expodisc.Like the Whibal, Expodisc took the time to make a professional website with helpful video and written descriptions on what the disc is for and how to get the most out of it. I appreciate details like this, as I want to know what I'm getting and how to use it properly before I'm going to spend money on it. I also like the hand-documented calibration measurements I received in my Expodisc box. Nice!I can now see why so many people rely on the Expodisc, and highly recommend this to anybody that's been on the fence and overwhelmed with which white balance product to get. My personal recommendation: Get a small Whibal card you CAN keep in your wallet, and get an Expodisc you can wear around your neck when your planning on using your camera and you're constantly changing photo subjects. Whether you get one or the other, or end up buying both, you'll be getting a very nice and easy to use white balance tool.Disclaimer: I don't really believe my computer and camera have feelings, nor do I think they want me to sleep on the couch....But if your camera could talk, what would it say????

### ⭐⭐⭐⭐⭐ Excellent
*by M***J on May 8, 2013*

I'm a semi-pro photographer and I was looking to speed up my workflow, particularly with weddings. I was using auto white balance in camera and color correcting in post processing. You can imagine how time consuming this process was. I saw several photographers recommend this product and I was skeptical. After a few sessions my verdict is: it really works!!I use it to take my exposure reading first, then custom white balance on my Nikon D800. That's it. You can change your exposure and don't have to take another white balance. If you change areas or the light changes, you have to take a white balance reading again. It takes a little practicing just to get fast with it. It's worth the 30 seconds it takes. The color is spot on and I don't adjust white balance anymore. I get that done during the session or event.You can take the white balance by standing where your subject will be standing and pointing the camera where you will be standing OR by pointing the camera towards the primary light source. In my experience both methods worked. I find in a shaded area, it's best to point towards the primary light source so that your white balance isn't too warm. Some people get caught up in the exact method, but really either works. You can watch video tutorials on their website.The other benefit of this method is that I can show a quick preview to the client from my camera and the photo looks really nice. Not all cold and dark like it would with auto white balance. If you're debating getting it, just do it! I must have for semi-pro or pro and good addition for photography lovers. I would order again without thinking about it.

Actually a very good, accurate, white balance reference product. However, does little more than the $1-or less gray reference card that you own. Don't get me wrong, this device does produced a very high quality white balance reference. If you are a professional photographer, you probably have this or something like it and definitely need it. If you are not a professional, check your closet and see if you have one of those "collapsable gift boxes", (you know the kind where you get a shirt or a hanky for Christmas). I can't tell the difference in any of my photos using either of the devices. The procedure for the WB reference is definitely different, but the result is almost identical. Auto white balance in any DSLR camera is risky. This is especially true in portrait modes. If you are unsure of the color of the card, or don't like the results of the reference, buy a gray reference card from your local photo supplier.
