Writer-Director David Lynch develops a film by coming up with 50 memorable images.
That obviously works for a screenplay because movies are a visual medium, but it’s also very effective for any novel or work of non-fiction. And you don’t need 50. Consider all elements of your project that have a visual aspect:
1. Objects
2. Clothing
3. Physical Qualities of Characters
4. Locations
5. Environmental Details
6. Events
7. Visual Metaphors
Visual motifs create continuity. They help make a project coherent, vivid and memorable for the reader.
SUPER-TIP:
Objects = Emotions
In film and literature, objects equal emotions. Think about what the object represents to you, what it means to various characters and how else it can be used in the story.
In “The Hunger Games”, the mocking-jay pin becomes a symbol of the bond between Katniss and her sister, then the birds themselves become a symbol of the bond between Katniss and her ally in the games, plus a practical tool for them to communicate with each other: a symbol that is visual, tactile and auditory.

Perhaps, auspiciously, semiotics is the name of the game here. I also think that interpretively, any flinching (such as gesturing) can evoke emotion.
