Vellatura
Misura
A trial of measurement — not a reading.
Four taps — the inside of your forearm, your cheek, your hair at the root, and your bare lip. Then three questions, already answered, for you to correct.
Before you begin
Open your phone's camera app and turn off beauty mode, filters, portrait enhancement and skin smoothing. Many phones apply these to the front camera by default. If they are on, every reading is wrong in the same direction and it will not show up anywhere.
The rear camera is usually unprocessed and truer — use it with a mirror, or a helper.
