Watching this week's episode, I think TAR should relax their trying to avoid seeing the cameramen and sound guys in shots. When Amy & Maya (I think) passed Brooke & Robbie in the taxi, we saw the cameraman clear as day in the front seat and that was great. It really added to the excitement.
But for example at the Detour, when the three teams were in a mad dash to get to the scaffolding first, I feel like we missed some great shots because they probably had a cameraman or two in them. That seems to be the case a lot of the time, otherwise usable shots that must be thrown out because of either of the crew members being seen.
I think after 25 seasons, TAR doesn't need to be as careful or active in trying to hide them anymore. Sometimes, especially in the more frantic scenes of the Race, it adds a lot to the excitement and avoids the need for abrupt quick cuts.
