Nature photography that captures new perspectives of the ocean, sky, or forest is a great way to experiment with texture. Aerial photography of the ocean can be unrecognizable, as the colors and shapes of the waves blend together. The geometric shapes of an industrial building may look like a patterned textile if you shoot it from the right angle. Whatever you choose to capture, taking a subject out of context and focusing on its textures and tones can help you create amazing abstract work.
Capture objects in motion.
Traditional photos are taken with a fast shutter speed and capture a single moment, frozen in time. When you add motion to the image, it creates some abstraction, and with a slower shutter speed, you can create long exposure photos. When you leave the shutter of your camera open for longer, you can capture the motion blur of a car traveling down a street. By keeping the camera still, you can record the motion of the car in your shot and keep everything else static. The car will look like a streak of color across the image, while the rest remains recognizable. Now consider exploring the motion blur of continuously moving things, like water or smoke. By bringing new elements into the image, you can transform ordinary things into the ethereal.
