No its more a case of politeness that if youve ended up with a massive close up of someones face that you intend to use then be nice and check with them first
There’s the moral element, the legal element, and also whether or not there’s any knowledge of what’s on camera. (Particularly with fish eye lenses on action cameras)
For the OPs question they would be wearing a video camera. Safe zone footage from head cams is very boring.
If it’s uploaded raw then it’s likely that few people will watch long enough to see
If edited then even at the minimum it’s likely to have safe zone footage cut out in preference to game footage.
But you do get videos of a days ‘story’ that could have safe zone footage.
For battery life it’s common to get into the habit of switching on & off to avoid wasting power and card space on the boring stuff
If you don’t want footage or pictures of your face out there, then help people out with that by letting the site know (they are the authority on what people are allowed to film/photograph on site)
If a camera is around you then a polite mention makes it clear
My interest in photos is different. I do like good action shots, but the majority of the best pictures I’ve taken are in the safe zone. I won’t be asking permission to take a photo - I’ve then lost the ‘real’ moment of that picture. I’ll lift the camera, allow for that moment of a ‘no face’ and snap the shot. You still have the option of saying you have an issue with it
(I’ve had that I think on only two occasions - and both of those were people who weren’t supposed to be there, they only asked that I don’t publish those photos but I deleted them as an unusable photo is no good to me and it also avoids accidental publishing)
However - I would be taking those on the basis of ‘officialdom’ and you would have already consented that photos are being taken.
Candid safe zone photos are the ones that I have sold most often - so they can give a nice photo to their mum, or new profile photo. The rest would have to have caught a particularly interesting action shot, or the full set of a team etc
My pictures also go to my general use, they may be for the site/event, Facebook galleries, portfolio and also photography competitions some which have gone to art gallery exhibitions.
If I’ve taken the photo legally then it’s my property to use.
In street photography there’s the same situation, there’s no disclaimer with the small print giving consent. It’s just the shot being taken, I’ve had some refusals but most of the time there’s no issue.
