I've always felt that composition in street photography is tough. You have to capture the moment, and yet compose it well, e.g following rules of 3rds (just an e.g., I know that in the right conditions, "rules" can be broken) If not, I feel that the photo that comes out will just be another photograph of a person walking by. There are a lot of photos that I see on flickr that somehow lack an impact. I can't quite put my finger on it, and explain it explicitly.
I know that there are a few of the street photogs here who do it consistently well. Maybe you guys can share on how you managed to achieve such consistency.
I am not talking about just methodology here like shooting from the hip, but also how you trained yourself to see and capture good street photographs.
Hope this will spark a lively discussion from those whose passion is street photography.
