Depends, I suppose. I tend to seek out people who don't know I'm photographing them. I absolutely don't want the individuals to inject my presence into their reactions. That ruins everything for me.

YMMV, of course.

This also does place a tremendous ethical responsibility on me to never intentionally depict someone in a bad or compromising context. As a practical matter it also normally precludes obtaining model releases. But I do this only as an avocation, so that doesn't come into play for me.
