Most digital cameras these days have a multi-exposure mode. If you like the idea of impressionistic or abstract art, set your camera to multi-exposure mode and fire away. Move the camera a little between exposures, or zoom in and out, or swing the camera around to another point and superimpose new images on the previous ones. You may get a lot of junk, but you also may get some keepers.
Gear Photos were made with a Nikon D750 and a Nikon 70-300 mm f/4.5 - 5.6.
