Besides Street Photography my current favorite form of photography is Minimalism. I found out about Michael Kenna a few years ago, and my mind was blown. I used to leave my camera at home on bad weather days, now I look foward to them. Negative space is king.
Most of the below images were taken handheld, but a few were taken on a tripod with a 10 stop ND filter. I would suggest this method as much as possible to create the desired effect.
