A good way to make a light trap is a cone painted with

So the camera looks into the pointy end?
Otherwise it seems to me that the light gets reflected back.


Yes. Think of an ice-cream cone. Look at the inside,
and paint it glossy black. A machined metal (like aluminum)
works very well.

Wouldn't machined (or even moreso, polished) metal reflect much more
light?
Why did you pick glossy black?
