SKILL: Resolution & Aspect Ratio Language

Version: 1.0 | Hermes Agent SD Prompt Craft (Technical)

DESCRIPTION

Mastery of dimensional control in AI image generation. Aspect ratio is not merely a crop — it is a compositional command that dictates spatial logic, subject framing, and environmental scope [^63^]. Resolution determines pixel budget and native detail. Each model has specific sweet spots, increment constraints, and optimal ranges [^58^].

ASPECT RATIO AS COMPOSITIONAL COMMAND

The Hidden Impact: When you specify an aspect ratio, the AI optimizes composition for that exact frame shape. Generating square and cropping later removes context the AI specifically included [^58^]. Match ratio to subject matter from the start [^63^].

Vertical Subjects (People, Trees, Towers):

• Ratios: 9:16, 2:3, 3:4, 4:5
• Why: Provides vertical pixels for full body, height, upward gaze
• Risk in wide ratios: Head cut off, body warped to fit sideways [^63^]
