As a writer of fiction, my priority is to make what is unseen easy to visualize. I do so by simplifying the concepts and generalizing the descriptions.
What things look like is important. This is a problem as words, however. Elaborate descriptions are inappropriate. An illustration should be provided if the exact details are so important. The story is brought to a halt otherwise.
Some ideas cannot be illustrated. They are matters of preference. For example: “The most beautiful woman in the world” can be contradicted by a picture, no matter the picture. If a subjective concept is important, what is visualized should be left to the imagination of the reader.
Pacing is especially important in action scenes. The gist of what is happening should be described, not the details. The emotions and sensations of the characters involved are what make action in prose dramatic. Exact measurements and positioning are generally irrelevant. No one in such a situation would mind such things anyway, instead acting reflexively or intuitively.
Less is more in reading or writing prose. The gist is what makes everything imaginable. Generalizations give the feel that makes things seem as they are. If a detail is mentioned, it should be important, such as to hint at significance. Extraneous details should be omitted entirely. The mind of the reader should not be overwhelmed by irrelevancy.
A picture speaks a thousand words, yes, but using a
thousand words to draw a picture is not only inefficient, it is too much. A
book should never be longer than its actual story.
