A simple photography composition tip: tilt your camera (Dutch angle)!
By tilting your camera, you make your compositions more dynamic. For example, see this picture of a boy I photographed inside a restaurant. I shot it with a 24mm lens, and I tilted the camera to the left. The photo feels off-balanced, like he will fall off and slide off to the left.
Better with wide angle
Practice the Dutch angle composition (tilting your camera) with a wide angle lens, like a 24mm or 28mm lens.
Have fun with it! Don’t take it too seriously. Experiment with your composition like a child, with a spirit of play!
A simple way is to just experiment with trees or architecture.
You can also look for lines, and make it tilted. For example this street photo of this woman in Japan through a dotted pattern. Note the line on the bottom is tilted.
