Light is a huge tool for photographers to use to convey mood and tone of the photo. For example, using darkness can signify something negative or heavy in mood, while light can signify something more happy.
I love how light is used to convey mood and whether the photo is supposed to be happy or sad.
This tool was from “Photography Life”.

Depth between subjects of the photo creates a contrast between the objects to emphasize differences between the two and what they mean. Depth and contrast are closely related, in my opinion, and both of those tips were separately mentioned.
This tool was from “Digital Camera World”.
I like how depth can change the size of the object. I love using depth to make smaller objects to larger, especially compared to other objects that are supposed to be much bigger.

Perspective can give context to the viewer and impact the view of how they are intended to perceive the subject of the photo. For example, looking down on the focus of the photo suggests inferiority or smallness, while looking up at the subject makes it look dominant.
I was already a fan of using perspective because I love how it can help shape how the audience feels about the person or object in the photo. It is one of the biggest tools to give personality to the subject.
Above is the link to the article that I read about perspective.
