In my country, the Netherlands, you have to get permission if your spreading somebody’s picture, whether it is a public space or not. It is the same in the rest of Europe.
The famous GDPR: general data protection regulation.
Taking the photos is no problem, spreading them is. Before the GDPR there was a difference between public space and private space, but now there is not.
Recently there was a funny discussion in my country.
There is going to be a big bazaar, where all sorts of food are presented. The organization asked people that are planning to visit the place to stick a red round label at their forehead, available at the entrance, to ensure that the professional photographers that will be hired will know whose faces they should blur when publishing the pics.
Lots of people objected to that ridiculous opt-out.
So basically Alrik acted right and I acted wrongly.
I frankly forgot all about this GDPR when posting the photos, it is rather new.
When posting I only though of how I would like to be treated when photographed in public…
