The key to photorealism isn't the subject, but the Light. AI is trained on professional photo captions, so it understands technical lighting terms.
Prompt Light Dictionary
Avoid 'good lighting'. Use these specific terms:
- Volumetric Lighting / God Rays: For light piercing through dust/fog, giving spatial dimension.
- Rim Lighting / Backlight: Light from behind the subject, separating object from background (silhouette).
- Subsurface Scattering: KEY for real human skin. This simulates light penetrating skin layers (ears glowing red when backlit).
Prompt Example:
Portrait of an elderly fisherman, hyperrealistic, weathered skin, subsurface scattering, rim lighting, volumetric fog background, shot on 85mm lens --v 6.0
