Asked by: Oleksa
ExpoDisc 2.0 77mm White Balance Filter V2 uses multiple layers of materials to achieve an 18% light transmission across the visible spectrum, and do the final calibration and QC on a transmission spectrophotometer to certify the results. You will get more accuracy on your camera dynamic range and white balance.

question

Is it best to aim at light source or just in the room where pics will be taken?
Asked by: Anonymous
There is no right or wrong when it comes to this. My best advice is to take a few test shots the first time you use it to become familiar with it. I most commonly aim it towards the light source for my test shot, but there is nothing wrong with aiming it at your subject matter either for a reflected type reading.

question

WHY ONLY 77mm?? ANY PLANS FOR A TOOL LIKE THIS IN 52 TO 72mm??? BIG MARKET OUT THERE BESIDES 77mm!!! JIM D SMITH
Asked by: Anonymous
Unfortunately, the other sizes have been recently discontinued. 77mm is the most common of the larger filter thread sizes, and will cover the area of any lens with a smaller thread size. All you need to do with a white balancing filter is hold it briefly in front of the lens to gain a proper balance. Its not a type of item that you would leave on the lens all day to require a dedicated size.

question

Before taking the test shot, do you set the camera to AWB or Custom White Balance? Or something else?
Asked by: Anonymous
I'm an amateur photog. Having said that, it's not quite as simple as setting your camera to Custom White Balance. I don't have my ExpoDisc2 info sitting here in front of me, nor do I have my Canon "how to" book. However, using the ExpoDisc2 with something like a Canon T5i or Canon 80D is fairly easy, but contains about 10 separate steps. Don't let that scare you. After doing it four or five times it gets easy. I laid out my steps and typed them on Word. I keep a copy of those steps in my camera bag all the time - just in case I might overlook a step. Once you get the hang of it, setting the CWB on your camera will take you about one minute.

will it work on a film camera ?

will it work on a film camera ?
Asked by: Michael
Yes, although without the instant feedback of a digital camera. The resulting “gray” photograph can then be used as a WB reference when scanned into software for post-processing. Color variables are introduced via that process, so accuracy may be affected, but that gray is still gray.

question

Would this work on a Sony AX-2000 video camera?
Asked by: Anonymous
You will need to use a 72-77mm step up ring http://bhpho.to/1orAEU6 to use this filter with the Sony AX-2000, and remove the factory hood. One could also just hold it over the lens front to check the white balance. It is not something that you keep on the camera.

I hesitate what expodisc I have to buy, 77 or 82 ...

I hesitate what expodisc I have to buy, 77 or 82 mm. My larges lens I usually use is 77 mm, but I have a Rokinon 14mm with more diameter. What I ask myself, if the expodisc will work with the 14mm Len, due to the curve surface and the petal-type lens hood, I believe, the light will get throw the sides between the hood and the expodisc when I hold the filter in front of the len. What will advise me?
Asked by: Anonymous
I would get the larger one. The 77mm might work for the larger lens, but both discs are the same price, so why take chances?

question

Would this expo disc work with a 82 mm Sigma lens?
Asked by: Anonymous
In this case, it would be best to get the ExpoDisc 2.0 82mm White Balance Filter, B&H # EXWBF282, which can be screwed into your current lens or held in front of a lens with a smaller front diameter. https://bhpho.to/2lWzPyX
