Options explained
- Style
- Grayscale keeps natural shades of grey for a classic black-and-white photo. Two-tone forces every pixel to pure black or white for a high-contrast, stencil-like effect.
- Threshold (two-tone only)
- The cut-off between black and white. Lower keeps more white, higher makes more black — tune it until the shapes read clearly.
