Human Focus Photography

Human Focus Photography is a general-purpose LoRA trained on diverse photographic portraits and lifestyle images. It is intended to reduce bias, enhance realism, lighting, and natural detail across a wide range of subjects, making it well-suited for portraits, street scenes, fashion, and candid photography styles.

Workflow is included in the sample images.

Training for v1.0 took around 17 hours on my 5090
