As an adjunct to the Tangents blog, the intention with this forum is to answer any questions, and allow a diverse discussion of topics related photography. With that, see it as an open invitation to just climb in and start threads and to respond to any threads.
Thank you Mgraber. I would be using a wire. Wasn't sure if the beam needed to be coming from the camera position. Sounds like ( if the beam is sufficient) it dosn't matter where it is coming from as long as the lens and camera can see it.
It appears that no one noticed my original post. I'm a bit new at this forum stuff so I'm not sure as to why there haven't been any responses to my issue. Was it something I said or am I the only one in the room?
