Does anyone white balance using the style of balancers that clips on like a lens cap? Any suggestions on brands/models? Thanks.
Lens cap style white balancers?

Somebody once told me, one of those white paper coffee filters that cost $2 for a hundred, are exactly the right color and transparency to use as a lens cap white balance filter. A rubber band is the preferred attachment device.

I made one using two super cheap UV filters with a coffee filter in between. The coffee filter worked better than the lens cap but not as good as the Expodisc.
I wonder how that could work? For example...
If we metered the actual light source (like with the light reflected from a neutral white or gray card), and set white balance for the light, then anything in the scene in that light should be rendered without color cast. For example, if the scene were somehow all bright red, it will still appear red in any light, assuming with the proper color balance that makes that neutral card be neutral in that light.
If we cover the lens with a filter, it sees the light reflected from the scene, not the source. In this case, the bright red scene. And if we make that red light be neutral,then our red subject becomes white or gray, not red.
Since that can't work, I suppose you must have to aim the filter at the light source, not at the subject? So you take the camera and filter to the subject, and aim it back at the light?

Yes... That's how you use all the disk/filter type constructs to set the WB, you aim the camera at the light source....
