The way I have this photo set up implies a stark contrast between the light and the pitch black darkness surrounding it.
Balance
Both sides of these doors are symmetrical. Implying balance.
Texture
The rough and tough element of this piece shows texture.
Emphasis
Both of these trucks are painted black and white, but the strategic placing and the abundance of white emphasizes the white paint in these cars. Like if you saw these cars, you'd refer to them as "white cars", when they're really black and white cars. Pretty neat.
(Probably) Rhythm
The repetition of the cubic blocks, and the grey color with the variance of overall shape, and variance in texture adds up to bring rhythm to this part of the GHS structure.
Pattern
The figure of repetition and the lines bring out the pattern principle in this design.
Space
All windows in Glacier High are evenly spaced, including the ones in this example.
Color
The gold and black colors in this picture compliment each other to create a trophy that signifies strength, wealth, and accomplishment.
Form
These cubes are 3D shaped, implying form.
Unity
I like how these rocks, despite varying shapes, sizes, and colors, all form together to create one single texture. Implying unity.
Movement
To take this picture, I just started swing my mouse from the table. The way the mouse and mouse wire are positioned implies that the mouse is swinging back and forth, which implies that motion is going on.
Value
This puts an emphasis on value by going from dark concentrated ink to a lighter shade.
Shape
The shape of this shape is in perfect shape to shape the consensus that this implies shape.
