Restrict a scene's light sources in the prompt to practical (diegetic) sources that are visible or implied in-frame — sun, windows, lamps — rather than letting the model invent artificial extra lighting. Named as the specific fix for the common "plasticky" or "plopped-in" look, where characters read as artificially lit against their environment rather than sharing its light.
Apply by naming the actual in-scene light sources explicitly ("practical light only, sunlight through the window") instead of generic lighting adjectives. Complements "Cinematic" Decomposed into Camera/Lens Parameters (lens/camera specificity) and Tighter-Frame Rule for Reduced AI Artifacting (another concrete fix for a named AI-video artifact) as part of the broader pattern of trading vague quality language for a specific, checkable constraint.
