As Eric says...."Reversing the same incident meter and pointing its cone AT the subject invariably gave a less precise exposure.
Of course the cone took a very wide angle of view. The very quality required for accurate incident reading!"

This why you need to point the invercone back from subject to the camera shooting position.
This makes incident light metering more difficult, but provides a more effective measure of exposure.

Of course they are totally useless when photographing the moon. :lol:
