What composition really is: deciding what the audience sees first, then next
Composition is arranging the things in the frame to guide the audience's eye. Same people, same scene — arrange them differently and the audience's attention and emotion change completely.
A few of the most common: symmetry (left/right or top/bottom mirrored) = order, stability, ritual; rule of thirds (put the subject on the lines that split the frame into thirds) = natural, comfortable; leading lines (use roads, railings, or light to pull the eye to the subject); negative space (leave a big empty area around the subject) = loneliness, room to breathe. (The rule of thirds isn't only about the intersections — you can also place the horizon/subject along a thirds line.)
Symmetry vs. negative space: two opposite emotions
Symmetry feels controlled, orderly, even oppressive (Wes Anderson's frames are almost all symmetric); negative space feels lonely, free, full of room to imagine. To show someone trapped by rules, use symmetry; to show them small or alone, put them in a corner and leave the rest empty.

Using a road, railing, or light in the frame to pull the audience's eye all the way to the subject — which composition technique is this?
答案:Leading lines
Using lines to guide the eye to the subject is leading-line composition.
You want to convey a character's oppression at being firmly trapped by rules and systems. Which composition fits best?
答案:Strict symmetry
Symmetry brings order, control, even oppression — best for 'trapped by rules.'
True or false: the rule of thirds is an iron law you must obey, and putting the subject dead center is always wrong.
答案:False
The rule of thirds is just a safe starting point; many masters use dead-center composition for strong impact. Rules serve emotion, they aren't iron law.
