The document discusses three photography techniques: double exposure, light writing/drawing, and motion blur/movement. For double exposure, the photographer likes overlapping images to create blended, interesting compositions, and can use one image as a frame for another. For light writing, the camera shutter is left open as a light is moved across the frame, recording its trail and standing out against a dark background. For motion blur, movement is captured as lines of softness or color against a crisp background, and the photographer prefers images of moving vehicles to people as they add more vivid color and lines.
