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.

Recommended settings

Flux guidance: 3 (2.5-3.5)

Denoise: 1 (0.95-1)

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

• Sometimes faces may be slightly elongated

• Doesn't work as well for landscape orientation

• Mixed results with multiple subjects
