Illuminate is a bidirectional SDXL concept LoRA that controls the apparent illumination of an image while attempting to preserve its underlying subject, composition, and scene semantics. Negative weights progressively reduce illumination and visibility; positive weights increase illumination, exposure, and the apparent amount of light present in the scene.
Unlike a simple post-processing brightness adjustment, Illuminate operates during generation, allowing the model to reinterpret lighting in a scene-aware manner.
Range
Recommended experimental range: -4.0 → +4.0
Intent
The intent is not merely to make pixels darker or lighter. Illuminate is intended to provide generative control over the semantic concept of how illuminated a scene is.
Ideally, that means it can alter things such as apparent light availability, exposure, shadow depth, highlight prominence, visibility of surfaces, and the model's interpretation of the lighting environment, while leaving unrelated concepts compara…
