I recently attended a wedding as a guest (first time in a while!) where there was a crew of three videographers and a photographer shooting all day.
The videographers make excellent videos and I was impressed by the documentary style they have (cinecraft.com.au)
However, I did notice that if I were the offical photographer, nearly all of my shots bar closeups would have included the videographers. Their style is that one of them filmed with a 100-400 and was able to stand back, one of them shot a wide angle from a distance but the third videographer literally tailed bride and groom everywhere 1-5m behind with a lens I couldn't identify.
This is just theoretical question but if you were photographing the wedding, could you ask the tailing videographer to step aside? Would that compromise the video?
Or would it require some discussion between all parties beforehand as to what the bride and groom thought most valuable - a great video (vs a corny nonsense video like the one I have which I never watch!!) vs great photographs without being filled with other parties trailing along?
