Fingerprint Modality
Capture Your Ridges
Your fingerprint pattern becomes a uniquely articulated composition
Step 1 of 2 — Macro Capture
Position One Fingertip
Hold a single finger 5-7 cm from the rear camera. We auto-trigger only when the readout below is all green.
Finger shape & placement
Press the pad — not the tip — flat onto the rear camera. Cover the flash with the side of your finger so the light passes through your skin and lights the ridges from beneath. Hold still ~1.5 s — we capture a 3-frame burst and keep the sharpest.
