Objective, Subjective, Figurative Description
Objective description is primarily factual, omitting any attention to the writer, especially with regards to the writer's feelings. Imagine that a robotic camera is observing the subject; such a camera has absolutely no attachment or reaction to what is being observed.
Subjective description, on the other hand, includes attention to both the subject described and the writer's reactions (internal, personal) to that subject.
Figurative description relies on creating likenesses between objects, often through simile (e.g. like a snowflake...or fragile as a snowflake...) or metaphor. Such likenesses allow the reader to perceive the object more precisely.

(Notice how "objective" the narrator in the piece is; his or her eyes scan the scene, but there is no emotional response provoked by the scene).

Cut from the sturdiest oak, the table was tough, smooth, and long enough for my mother, my two sisters, and me to work or play on at the same time. Our favorite light blue ceramic tile, stationed in the right corner, was the table's sole defense against the ravages of everything from a steaming teapot to the...
