Creating stunning images is a function of composition and exposure, light and shadows. These days however it is relatively easy for photographers to use software like Nik, Topaz, and OnOne to add painterly affects and texture to enhance an image during post processing.
On this image I used Topaz and within two minutes, added texture and turned a color image into black and white. There are countless tutorials on You Tube as well as on the manufactures web site. If you have never used these programs download a free trial and have some fun.
