In response to the post about street photography, or rather, some of the comments made there by Stefan, I would be curious to hear some comments on how to be discrete in photographing strangers. I am interested in three topics, but welcome other comments:


First, what are your thoughts on getting over the awkward feeling of photographing strangers who know you are photographing them (just do it a lot?)?


Second, what are some tips to avoid detection (obviously size of camera/lens, color...Stefan said take a girl when you are shooting children)?


Third, are there any legal issues with photographing strangers? At what point do you need a photo release?


And of course I welcome any humorous or shocking stories of related situations. Thanks!
