I had a fun experience with the Instagram-effect recently. I tried to visit an arboretum earlier this year (don't judge me, it's interesting!) and I couldn't get near the viewing platform because someone had a crew lighting their shots for Instagram. They asked me to wait for a couple of minutes to get finished, which I did. Ten minutes later a crowd had built up on the ramp and I just pushed past and said "all right good work today everyone we got what we need that's a wrap!". It's nuts.
It's also weirdly disturbing to me that the presence of someone with an expensive looking camera was enough for a lot of them to just walk on past instead of enjoying the day out they paid for.
In my experience, professional productions are usually very intentional about not getting in the way of people just trying to go about their day. We were filming at a busy coffee shop in January, and we held for filming whenever a customer wanted to buy a coffee. The producers were pretty serious about not disrupting the business we were filming at.
Why would you be judged for that? Botanical gardens are great.
I'm a naturally nice guy, but these people were making my vacation less enjoyable for no reason, and I felt an instinctive urge to ruin their experience as well.
Museums are usually closed on Mondays, why not make "photographer Tuesday" a thing for instance?
