Hi gang,
I have a general question re: dome ports. I gather that the reason to use a dome rather than flat port in u/w imaging is to widen your angle and cut your physical distance to the subject. Is that about right?
If my cam/housing with a flat port currently has no vignetting, how can I find out if a 60* or 90* dome port will cause vignetting?
I don't really understand how the dome changes the focal length or angle. Can somebody explain it?
Thanks.
