George, thanks for the link. The disguise section is really cute...funny stuff! I think, hope, they are only kidding.
I am a lady so perhaps it's easier for me to "intrude"...dunno. I do always ask parents for permission to photograph their kids, and no one has ever said no. They never even ask why...they are just flattered that I think their kids are cute. Perhaps a man would have a harder time getting permission however, with all the news these past few years about pedophiles. I think the best idea is not to use a disguise or fake personna, but just to be honest and say you love people pictures and find the person/s interesting. You can't go wrong with the truth, right?
I have a question. What do folks here consider to be a "candid" photo? I see that in some of these the subject is looking at the camera so is aware the pic is being taken, and in others not. I prefer to think of the former as unposed or informal pics. For example, this is one of my favorite photos, it's unposed, and she only noticed me as I was about to snap it. So, candid or not? Or does it matter?
I'd really like to know what everyone thinks about the definition of "candid" so I'll know what sort of pics to put in my upcoming gallery.
