I don't always ask, verbally, but I try to see if the person(s) are ok with me taking pictures right now, through eye contact or whatever.
When people are shirty because of 'that stupid camera' in front of their face it will show on the picture anyway later.
When there's consent, the pictures are usually much, much better.
On the other hand I know some people who are pretty successful with a rather forward approach,
and sometimes you need to be forward like that to get the picture, yes,
still it's nice if you can avoid acting like an asshole I think.
