Product Highlights
  • Quickly Set Your Camera White Balance
  • Works for Still and Video
  • Provides Accurate, Consistent Color
  • Calibrated and Certified for Neutrality
  • Use in Ambient, Studio or Mixed Light
  • Easy to Use, Durable, Compact

The ExpoDisc Neutral 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.

ExpoDiscs do not screw in. They lack front threads and were designed to be pushed-on over the lens threads in order to facilitate a quick white balance.

Helps eliminate undesirable color casts from images
Color corrects RAW or JPEG files
Calibrated for neutrality in the visible spectrum (400nm to 700nm)

    I had been using a grey card to perform my WB's. When I bought the Nikkor 80-200 f2.8 I spent the money and bought this on impulse that day. Best impulse buy I have ever made! It takes a little to get use to as it's tad different from how you use the grey card. I have used it on my 50mm as well to balance works awesome! This makes a great present for the holidays or birthday, but you or the person you get it for will not be dissapointed!

    I like using the ExpoDisc for shoots when I have the time to take the reading- using it for the wedding portraits inside the church. I've found that it's difficult to use in the reception venues since the lighting conditions change depending on where I am in the room. Overall it a good product when the lighting conditions don't change within the room.

      I used this for the first time on an outdoor "run & gun" video shoot that took place over one long day with endless lighting scenarios. This filter worked pretty flawlessly for correct color balance on the camera. I was very impressed with how quickly I could set the WB on the run.

        Purchased the 77mm ExpoDisc Neutral White Balance filter to help end my post white balance problems. Works great! Simple to use, I just followed the online videos, and got excellent results. Shot a NCAA Division I hockey game on a Canon 5DIII in a large arena with mixed lighting (mercury vapor, halogen, florescent, etc.) and got natural looking color without having to mess around in post processing. Superb results compared to presets. Really made setting a custom white balance a snap. The ExpoDisc has a permanent spot in my bag.

            I have watched many photographers online push not only the ExpoDisk but other white balance solutions as the only product you "really" need. I will confess that I own several! But after trying the ExpoDisk I have been completely sold. This is a no-brainer to use. Simply shoot one frame towards your main light (sun, strobe, or speedlight) and follow your camera's instructions to save that as your white balance. That's it! This past Saturday I shot an event that required me to move between 3 different rooms, all three with different white balances. Since I can save up to 6 custom balances, I recorded all three before the shoot and I was able to move back and forth with no problems. This was the first time I used my ExpoDisk and all shots were dead on. Do yourself a favor, get one of these.

                Simply as mounting the ExpoDisc over your current lens and setting your camera to manual white balance. Take a test shot and you're all set to go using that manula white balance setting for your lighting situation.

                  This really helps get the white balance dead on. No matter how fancy the cameras get they are still not as smart as someone with a brain behind the camera. I was shown the expodisc at a siminar and was skeptical at first but now own both the neutral and warming expodisc.

                      The ease of use is what attracted me to this product. Slap it on, take a white balance measurement, remove and shoot. The balance overall is good. The only issue I have is that with a clear filter on the front of each lens, the disc will not stay in place without a helping hand or gafer tape.

                      No more fooling around with built-in camera white balance settings. A must have tool for every serious photographers. I wished I got it sooner. The only negative, it will not lock in place on the lens, you've got to hold it or remove the lens UV filter to expose more threads for the locking balls to hold.

                              I'm not a professional photographer. I just bought more expensive cameras that I can afford and trust that I could get better pictures. How wrong it could be for me! A small tool that I should have had a very long ago is a very simple ExpoDisc. This indeed has given me a tremendous boost in my confidence when taking pictures.

                              I hope it would the same for you.

                              Comments about ExpoImaging ExpoDisc 77mm Digital White Balance Filter - Neutral:

                              I use the ExpoDisc to get quick and accurate custom white balance results from large coherent light sources. It is quicker than a grey card and, I believe, more accurate, although it is a little trickier to use, especially when there are multiple light sources of varying quality or temperature.

                                I knew about ExpoDisc but had not bought one because I thought I could always tweak the WB in Lightroom if it was not right. That was until I started photographing oil paintings. The colors were never right and only got worse when I tried to adjust them in post. Paintings are tricky, and artists want the colors exactly as they painted them. Then I borrowed an ExpoDisc from a friend and was sold. I immediately ordered one for myself. Be sure to watch the video about using ExpoDisc and take the reading exactly how they say to do it because it makes a big difference.

                                This product is very useful for when I bounce my flash off different coloured surfaces. WB is spot on! Only issues is the lanyard that comes with it is pretty short and I need to take if off my neck, all the time to set the WB. In addition, the EDisk does on fit tightly on the lens, not sure if it's because I use a Len filter. Overall very happy with product and Would recommend

                                  Coming from an optical imaging background, this product allows me to calibrate my white balance using the color temperature of the available light that will reflect off my subject as I would if I was in a optics lab. I prefer this method over correcting for white balance in post processing. I use this product when I see that the light source has changed over the course of the day and/or if clouds roll in or even if I am in shade. I love the way my whites are more truly white!

                                  Work great when photographing portraits however not as useful when doing weddings or children when things are constantly moving and the light with it. Works great for multiple light sources that can confuse the camera. Not great in lower light. Pricey for what it is
