Hi there. I'm new so forgive me if this has been asked. I have a friend who has a Manfrotto tripod with some sort of boom which allows for great shots of things below the camera (with lens parallel to object on ground) but without getting the legs of the tripod in the frame. I've Googled my eyes out looking for this but am not sure where to find it. Doesn't matter where it is located. As long as I have a name or examples, I can look for it. Anybody have any ideas? Thank you in advance.
