I joined the PhotoBlog Community today and first thing I searched for was Candid street photography and it landed me here.
I like doing candid street photography and have been doing it for the past two years.
I found a great candid street photographer named 'Thomas Leuthard' at Flickr.com. His work is very inspiring. I'm sharing a link to number of free ebooks Thomas has written about candid street photography. These books really helped me a lot in my initial endeavors.
There are videos available as well where we can see the genius himself at work..
All I can say is that a good candid shot becomes the best one if the shooter had a little more guts...
But I always use a camera that has a DELETE option... just in case you know...
I'm sharing my Photoblog and Flickr link below, in case you are interested in having a look:
Hope this helps.
