Gen-4 Image
Gen-4 Image creates images from text and visual references. Its product controls include resolution, seed and an Aesthetic Range setting for variation across a set of results.
References can describe different parts of an image
The reference workflow can combine a character, environment and style from separate images. Saved references can be named and addressed in a prompt. Runway recommends neutral expressions and even lighting when a subject must be placed into different scenes.Gen-4 Image reference controls
Sketch references can indicate composition, object placement and gaze. They are inputs to the image model, rather than finished output. Review whether the generated image preserves those intended relationships.Gen-4 Image reference controls
Control exploration separately from the subject
Aesthetic Range varies from zero to five in the product guide. Higher values allow greater creative variation. The Vary action produces another set from an existing result. These tools serve exploration; they should not be confused with a promise of exact identity or layout preservation.Creating with Gen-4 Image
