Boom Headshot! Zooms into a face and enhances detail. Works much better than vanilla kontext.
In comparison images, the cropped original is an auto bbox crop with yolo which is something you can use but this lora could probably replace a face crop + upscale in your workflows.
That's it. Don't add anything else.
Flux guidance: 3.5 (2.5-3.5)
Denoise: 0.95 (0.90-0.95)
Strength: 1.25 (1.00-1.25)
Limitations
It's not magic, heavily pixelated or noisy images won't work well
Seed variability, if it doesn't get the correct crop you want try a different seed
Eye color and fine facial features sometimes inconsistent. My training resolution is GPU limited, may try and find a solution...
