SKILL: Blue Hour & Silhouette Lighting

Version: 1.0 | Hermes Agent Twilight & Shadow Cinematography

DESCRIPTION

Mastery of blue hour twilight cinematography and silhouette lighting techniques for AI-generated campaigns. This skill encodes the visual grammar of the liminal zone between day and night: the specific color temperature of deep twilight, the dramatic power of silhouetted forms, rim light separation, and the emotional register of shadow as subject rather than absence. Essential for creating images of mystery, transition, isolation, and grandeur.
