PS some sample shots created by another photographer: http://blog.instagram.com/post/66187514665/howishootwater

Edit: I just discovered Flickr is filled with em. Some good examples on what happens when the number of shots you select (anywhere from 4-64 I believe) is less than optimal if you scroll down: https://www.flickr.com/search/?q=%23avgcampro

I use Avg Cam Pro in touristy situations with lots of movement. Take 64 shots and (moving) people simply fade away by the time you're done.
