Re: How do you do that Spotlight/Light Beam effect

I suspect it is a post-processing job. If an optical spot was used to illuminate the subject, it would not be as sharp around the edges on the background- unless she was almost touching the background. The shadow on the background indicates that the light was coming in at an off-camera angle of about 30- degrees- that would not cast a perfectly symmetrical circle on the background.  If it was a cut-out circle adhered to the background ho do you account for the fall-off at the bottom of the frame?  The subject's legs and the cove of the cyclorama show at a different opacity. Maybe some kinda overlay?

If an optical spot was used to cause a similar effect on the background it would have to be co-axial with the subject, hidden behind her, and there would have to be sufficient depth of field to render the beam with a sharp edge.
