These were easy to do, no tripod needed or fancy smancy camera attachments. Both were shot a few years apart, yet same technique. Canon 50D for top, Canon 5DMIII for bottom. Both with 24-105 f4 L lens. both at 1/4 second handheld. Experiment with a few different exposures and shutter speeds when you do it. Top is created while zooming out. Bottom created by zooming in. Colors done by playing with all the sliders in Lightroom.
Do this while twisting the camera and you'll see why ND filters are necessary.
