Thanks for your extensive reply Mel, I appreciate it.

I am also not interested in taking pictures of beautiful girls wearing only their panties. My self preservation instinct tells me that my wife would not appreciate that so much
I'm interested in taking pictures of strangers, but not necessarily portraits. I want to get better in taking good candid pictures that tell some story. That is one of the reasons I got my 55-250 mm lens, so I can take pictures of people in their natural behaviour, not thinking they are posing for some photo.
But I really like your approach, and I think it is a good idea to talk to them and have their permission to take the picture. Actually I just did it once, and I had the excuse that I wanted the picture for a photography contest, which was true. The difference is that I used my Olympus point and shoot to take the shot. I truly believe that pointing to someone with a SLR is more intimidating for the subject, isn't it? What is your experience? Do you think most people gets defensive when you ask them to pose for you?
