Tips for best results
- Soft, even light — face a window or use a ring light
- Hold steady and look straight into the lens
- Remove glasses — contacts are fine to leave in
- Sit where your webcam can focus — about a forearm away on a laptop
- We crop tightly to your iris — your face doesn't need to fill the frame
