Metaphors, similes, and creative imagery can be useful, creative tools for relaying emotion. In case you don’t remember, a metaphor, according to Reedsy, is “a literary device that imaginatively draws a comparison between two, unlike things. It does this by stating that Thing A is Thing B.” A simile compares things, usually with as or like.
Filmmakers carefully construct image systems similar to how writers use motifs in fiction: with color, placement, sound, or emblematic imagery. They are used to subtly manipulate the emotional state of the viewer.

Take the time to add these skills to your writer’s toolbox because they will help you become an emotional master.

I have a strong bias against the term “wordsmithing” because it’s often used to imply that a writer is like a mechanic who simply tunes up a story or an article that needs help–like there’s no art in the process. Nonetheless, this post from Jane Friedman’s site has some good ideas for those of us who are constantly trying to improve our stories, essays, and articles.
This post includes a fair number of examples that show just how “creative imagery” is used. C. S. Lakin does a good job with this post, one that veterans and emerging writers alike can read for fresh inspiration.
I find that these how-to posts remind me of techniques I learned a long time ago but haven’t actively thought about for years. They’re kind of a jump start.
