Photo to stencil

Turning a photograph into a stencil is a translation problem. A photo holds continuous tone, soft edges and colour; a stencil holds only lines and filled areas. Something has to decide which edges matter, which shading gets dropped, and where a shape should close so it can be cut or traced. These guides compare the ways of making that decision: an AI image model that redraws the subject as outlines, a threshold or posterize filter in Photoshop or GIMP that keeps only the darkest pixels, an online converter, or tracing by hand on a light box. Each method is tested on the same kind of source photos, with notes on where each one breaks: hair, low contrast, busy backgrounds, and subjects with no clear outline. The goal is not to sell one method but to help you pick the fastest route to lines you can actually trace, cut or transfer.
