I watched this series of Eric Kim videos a while back, and found them extremely interesting. Here's a link to the full playlist, It's 6 videos, nominally part of a Street Photography 'course'. The videos start at lesson 3 (1 and 2 are just slide decks). For me, week 3 (i.e. the first one) was exceptionally useful - Street Photography Styles. Whatever you think of Kim's photography, I think the videos are worth a look, especially if you're starting out in street photography (Week 5, video 3, introduces some classic street photography work).
