Framing :D

These two photos are framed using the photographer's surroundings. Both are landscapes with either natural or artificial borders and both are examples of what a frame is.

Rule of Thirds

These are examples of photos that use rule of thirds. When the photo uses a line (typically the horizon line) to create the idea of thirds in the picture it is called rule of thirds.

Simplicity

Simplicity is the lack of detail to provoke a stronger message in the image.
