User Quickstart Guide
As with the original ExpoDisc, a larger ExpoDisc can be used with smaller filter size lenses by simply holding the ExpoDisc over the lens during the white balance procedure.
Note, some smaller lenses may require use of a step up ring. Specifically we have heard feedback from customers that when using an 82mm ExpoDisc over some 72mm lenses, the filter and lens rings do not line up well. In this case a step up ring should resolve the problem.
The ExpoDisc is tested by hand on a transmission spectrophotometer and individually adjusted using custom formulated materials to ensure an 18% total light transmission across the visible spectrum. This neutrality is important because using a non-neutral tool for white balance can actually add undesirable color casts to images. Each ExpoDisc 2.0 includes a quality control card to certify its neutrality.
"When I got home from my engagement session, I uploaded everything and culled right away. I woke up this morning and started "editing"... 15 minutes ago. And, now, I'm done. I keep going back frantically feeling like I'm missing something. Why did it go so fast?? Why don't I have to really edit anything?! I had heard that the ExpoDisc was awesome for nailing perfect while balance, but what I didn't realize is that it also helps to achieve the perfect exposure too! The ExpoDisc is a game-changer for my business, and it was so much easier to use than I thought!", Tina Kraemer, Pure In Art Photography
