ExpoDisc v3 Professional White Balance Filter (77mm) - Easy White Balance

This is a terrific time-saver, as no color balancing in post production is needed, whether JPG or RAW to start with. This decrypts the trickiest lighting I've encountered, which is in gyms, stadiums, and their entry halls. No more purple performers! Works great! Love it! Buy one and you will too.

Very easy way to get an image to using to set CUSTOM WB in a digital camera. Yes, I know you can use a gray card, setting the FOV to include just the card and then take an image but with this, snap it on, point it towards your subject and take image. No muss, no fuss, no extra hands needed. Set WB and you're done. No need to frame up anything in the VF or dig out a gray card that either someone has to hold (I usually shoot alone) or set it on something (hard to do sometimes depending on where you're at). And since I use KASE magnetic filters on my lenses, I bought the 82mm version of the ExpoDisc and simply mounted an 82mm KASE screw-on filter magnetic adapter ring on it. A note here is doing it this way also provides me a way to mount the ExpoDisc without having to screw it on and off any lenses. Using a KASE 77-82mm magnetic step-up ring I already carry with me to allow sharing 82mm filters with 77mm lens filters, I simply magnetically pop on the 77-82 step-up ring onto any lens with 77mm front threads that I already have setup to work magnetically, then magnetically pop on the 82mm ExpoDisc on the front of the step-up ring, take the image, set the WB and I'm ready to go. Very quick and painless. I've used the ExpoDisc handheld version for several years and it works great. So does this version and once attached (however you do that) it doesn't require any extra hands.

Had to watch YouTubers to get a good idea how to use it. Once I followed a few steps, it truly works! I think it's a bit expensive and needs a bit of a handle to hold it over any lens. But I will use it every time! I use it for shooting artwork like watercolor and acrylic paintings.

I use this product because I shoot indoor volleyball and the light sources vary greatly (color, intensity, flicker, etc). Setting your camera's White Balance for the erratic light sources in these situations is essential. I have Version 1 of this product and it is AWESOME. I bought it over ten years ago and I still use it today with great results. I needed another ExpoDisc because I have a new mirrorless camera kit a that has it's own ExpoDisc. I tried to buy another Version 1 or even a Version 2 ExpoDisc (either new or used), but I couldn't find anything. So I bought Version 3 from Amazon. The product page lists all the improvemenrs to Version 3 over previous versions. It arrived next day in good condition. But upon inspection the latest version of this product is a serious step back in build quality. 1) Version 1 was made of thick metal and glass. Version 3 is thin plastic. I mean thin. 2) Version 1 had a nice snap/snap out in feature for use on a lens. This allowed you temporarily attach the device to the end of the lens, shoot into the light source, and then set the WB. When satisfied with the WB setting, you store it away. It doesn't stay on the camera. Version 3 apparently can thread into the lens like a filter. I'll never do this because it is made of plastic and I only need to use it for a few seconds. Who needs to have it mounted continuously? 3) Version 1 had a well made carrying case that was both stiff and well padded (no worries about having it in a crowded camera bag). Version 3 has a flimsy carrying case. No rigidity, almost no padding. It won't protect the thin plastic Version 3 ExpoDisc in a crowded camera bag. 4) Version 1 had a nice corded lanyard. Version 3 has a cheap cloth lanyard. Basically, EVERYTHING has become cheaper on this product as it went from Version 1 (awesome) to Version 3 (cheap). This isn't rocket science. This is a straight forward product with no moving parts. It serves an important but simple purpose. There is no huge leap in technology here. Yes it got lighter, but because the materials they used are cheaper and thinner. And the price didn't drop. I think I paid nearly the same amount 10+ years ago for a far better product. Shameful. Do yourself a favor, if you want this product, find Version 1. It is excellent. This version is NOT.

This version is definitely a vast improvement over version 2. I shoot in raw and in nuetral flat on nikon z7ii and did a few test pics just to get my feet wet and the white balance set compared to version 2 the colirs are are more rich and deep compared to a a flat look across the spectrum with V2. Considering I shoot in nuetral flat this is surprising when popped into lightroom and photoshop. My mainstay and money maker is black and white with the wider color spectrum set with setting white balance gave the test shots when converted to black and white more control when I set the color sliders for b&w color balance producing a richer b&w photo.

Unfortunately I never got to try it because it broke immediately. Decided not to repurchase after reading the reviews that may people were dealing with the same thing

Works well for setting white balance but I would suggest not using the bayonet step ring because it's all but impossible to remove. There are instructions telling you how to remove it but they don't work. It's also made of very soft plastic so it's very easy to damage.

This is good quality, I’m much happier with the result than the cheaper kinds. It also comes with its own case and lanyard. I personally believe it’s worth the cost over the cheaper ones.

This has helped better than a grey card for doing my WB on the fly. It has come in handy already on a shoot, and now there is no turning back.

Expodisc upgrade. V3 is an improvement over V1 and V2. Its major improvement is in being designed for use in the manner that they best used (Held over the lens, not clipped onto the lens).

Well made, excellent instructions…highly recommended.

Accurate white balance if used correctly.
