Rule of Thirds
Imagine your picture is divided into nine equal segments with 2 vertical and horizontal lines. Place the most important part of your picture on the lines or on the points created by these line segments. (some cameras will offer this function)
Balancing Elements
After using the rule of thirds find other objects to fill in the other line segment and/or points so that the picture isn’t as empty.
Leading Lines
Humans are naturally attracted to lines. Think about what lines you could use in your photo, this lines will help attract the viewers attention to the subject. Different lines create different views about the same picture. There are various types of lines, straight, curvy, zigzag, radical, etc and all can be used as a way to get the viewers attention.
Symmetry and Patterns
Include symmetry and Patterns where they are not expected. You can also make the picture interesting if you break the symmetry and pattern creating tension and a facial point
Viewpoint
Take time to think about where to shoot your picture from. Don’t always shoot from above, switch it up and shoot from above, the ground, the side, the back, a long ways away, or up close.
Background
Find a plain and unobtrusive background that doesn’t distract focus from the subject. A background that makes the subject stand out.
Depth
Photography is a two- dimensional medium so choose your composition carefully. You can create depth by including objects in the foreground, middle ground, and background. You can also overlapping or deliberately partially obscure one object with another.
Frames
Place natural frames like trees, mountains, arc ways, and holes around your subject.
Cropping
Crop tight around the subject to eliminate the background distractions (noise). This will focus the attention towards the subject.
Experimentation
Take a lot of different photos of something, try different things. Use the best photo and delete the rest. Just like when you take a selfie, you may take your selfie in a bunch of different way, then evaluate. Do the same to your object.
