Composition determines everything - stream and waterfall

Photography is about subtraction. Simplicity is beauty, but simplicity is not equivalent to being simple. In the early stages of learning photography, beginners often fall into a common trap: trying to include all the beautiful scenery in the frame, grabbing everything without discrimination, which makes the picture look very messy. The viewer cannot distinguish the main subject from the secondary elements, and also can't figure out what the photographer is trying to express.
