How to fix AI hands without rebuilding the whole image

A hand problem is often a contact problem

The model must solve anatomy, perspective, grip, object geometry, and occlusion in the same small area. Describe the physical relationship instead of asking only for a perfect hand: which fingers are visible, where the thumb rests, how much pressure is applied, and which object edges remain unobstructed.

Use a narrow repair instruction

Keep the edit area as small as the tool allows. State the exact correction, then list the accepted elements that cannot change. Broad repair prompts invite a new pose, face, product, or crop.

• Restore one anatomically correct hand at the existing scale.
• Match the current wrist angle, skin tone, light, and depth of field.
• Preserve the product label, face, wardrobe, background, and framing.

Reduce hand difficulty in the source frame

For future shots, simplify the interaction before generation. A stable palm, partial grip, or object resting on a surface is easier than crossed fingers, fast motion, or several hands sharing one product. Production design is often more reliable than repair.
