Palmprint Modality

Capture Your Palm

Your palm’s principal lines and texture map to melodic phrasing, harmonic intent, and rhythmic detail. Hold your palm flat with fingers spread, ~15 cm from the camera.

How to hold

Spread your fingers and align tips with the pegs — palm facing the camera, ~15 cm from the lens. Even light, no rings or sleeves over the wrist crease.

The shutter fires automatically once the detector sees a fully-open palm, well-centred, for 1.5 s.

Tips for best results

  • Hold your palm flat, fingers spread, ~15 cm from the camera
  • Even, neutral lighting — no harsh shadow across the palm
  • Frame so fingertips and the wrist crease both stay in shot
  • Remove rings, watches, or anything covering the palm
