Best Answer - Chosen by Asker:

Incident meters can also be used for available light!. I prefer to call them incident vs!. reflected light meters, but that's just how I was raised!. Incident readins are good for situations where you can not meter the reflected light from your subject, such as my Mt!. Rushmore picture which was made before they were clever enough to build meters that worked through the camera lens!. Probably 90% of my shooting in those days was done with an incident light meter!.Www@QuestionHome@Com

It looks like the Minolta IVF !. The white ball indicates it is an Incident meter!. Though if you know the answer, I am kinda confused as to why you would call it incident or ambient!. Wouldn't the question be Incident or spot meter!?Www@QuestionHome@Com
