possible they judged it a poor shot or just wanted a little extra drama and action for the camera.
i've been told clients sometimes ask the PH to back up their shot. some of the pro's on this sight can probably comment more accurately on that.
haven't seen the video so speculating.
personally never had any PH do ANY shooting, 4 ele. hunts and 3 buffalo, 3 different PH's. which doesn't make me an expert by any stretch of the imagination!
i've never had a video camera along on any of my hunts, but it sure seems like there's much more talking, shooting and interaction between the parties involved. and rightly so, they need to get the viewer involved and keep it exciting.
not my thing but to each his own.
