Landscapes are always on my mind! I'm constantly composing images in my head no matter where I am. Being outside is the key to capturing then!
Flowing water always attracts me (and often makes me pee) to find the right location, set up my tripod and play with my shutter speed, stopping the flow in a variety to stages.
Have done this on paper, canvas, metal and acrylic. Lots great in all mediums!
