Source description
Facezoom
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.
V1.1:
Trained at 1024px vs 768px Produces more consistent crops Better details
Less face elongation
Prompt
f4cezoom
Can add other face modifications, expressions, eye color etc as modifiers. Anything that kontext can do as standard.

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
Sometimes faces may be slightly elongated
Doesn't work as well for landscape orientation
Mixed results with multiple subjects
Trained with Ostris AI-Toolkit
