My broadcast engineering duties had me at the Chiefs vs. Colts wild card game on Saturday, and while walking the field after the game, I noticed a small remnant on the sideline which was a sure sign that NFL Films had been present...
For the record, that particular scrap was 7218 (Vision2 500T), although I wouldn't be surprised if they shoot a variety of stocks at any given game. Also, I was curious as to whether they used any special filters under artificial stadium light, however none of the 16mm cameras I spotted on the sidelines during pre-game appeared to be outfitted with filters.
If there's anyone associated with NFL Films lurking about, give yourself a big pat on the back...you all do excellent work!
