Hey guys, so here is something a bit unconventional but I've been finding REALLY helpful! I've never thought about doing this before, but google maps!
So here's what I've been doing, going to major cities and going to the street view level and BAM, I have a 3d image of people and architecture, look at this I used today -http://maps.google.com/maps?hl=en&ie=UTF8&q=healthcare+94102&fb=1&gl=us&h q=healthcare&hnear=San+Francisco,+CA+94102&view=ma p&cid=664428915857926981&iwloc=A&ved=0CBoQpQY&sa=X &ei=j3aGTLDaI5KCygThye21Aw
And the best part is, I can go back to this same street tomorrow and find a different image, with different lighting and people.
Obviously it's better for gesturals (in terms of drawing the people) but still I thought was a good idea.
Thought I'd pass the tip along .
