IDENTITY PRESERVATION INSTRUCTION
Using the uploaded photo as reference, preserve the person's exact facial features, face shape, eye color, skin tone, and unique characteristics while transforming the overall appearance into a medieval alchemist character.

TRANSFORMATION DESCRIPTION
Transform the person into a medieval alchemist from the 15th century. The subject should be wearing authentic period clothing including a weathered leather apron over a linen shirt, dark woolen trousers, and fingerless gloves. Add alchemist accessories: a leather satchel filled with glass vials and flasks, a brass or copper astrolabe hanging from a belt, and a weathered grimoire or ancient manuscript in hand or tucked into the belt. Include a small wooden table with alchemical equipment in the background (alembics, retorts, mortar and pestle). The face should have subtle weathering effects appropriate to a working alchemist - slightly smudged with charcoal or soot around the cheeks and forehead, maintaining natural skin texture. Add a warm, golden glow emanating from a nearby crucible or magical light source that illuminates the face dramatically.
