I was on a few different photographers sites and came across this picture: http://www.picturenuts.com/Henry/#gallery/5._Photo_Expeditions/3._Saskatoon_Night_2008/img/4 (I'd post the actual picture, but it won't let me) Can anyone tell me how much post-processing has gone into this picture? How much of it was actually captured, and how much of it was created after the fact? I really, really like this shot, but have no idea how I can take similar pictures myself. Thanks - really looking forward to everyone's feedback on this one!!
