Works fine, but usefulness is limited,
Verified Purchase(What's this?)
This review is from: JJC White Balance Filter, WB-F1 (Electronics)
This product is two pieces of plastic (the lens mounted in a holder), so there's not much to say about it. It's simple and does what it's supposed to.
However, it's advertised as a solution for all your white-balance problems. That's simply not true. At best, it beats "auto" mode. The problem is that it measures the incoming light spectrum, which means you have to have your camera set at subject's location pointing back toward where you intend to take the photo, and have the zoom set as wide as possible to get the best sampling of the incoming light.
In many cases that's impractical, and it's still an approximation anyway since light will be hitting your subject from 180 degrees. You're better off with a good white/gray reference card.

What you say is true. Incident light is the light falling on the subject. In most cases this simply means that as the photographer, you simply turn around and face the light. However in confined areas such as a studio, it is necessary to position the camera with WB filter as close as possible to your subject and pointing back towards the place from which you will be photographing.

No matter which disc you use, either the Expo Lens cap or this flat wide oversize unit, you need to sit where your model sets to get the correct light reading, by aiming back at your camera tripod. It's MUCH more accurate then a white card, trust me. For me, since I use 4 different cameras and 6 different lenses, I like this one better. The price had nothing to do with it initially, but I don't mind saving the extra $$$.
