Quick improvements:
- Light: Put a soft light 45° to your face; avoid overheads. Raise brightness instead of ISO.
- Angle: Camera at eye level, centered. Avoid “desk up the nose.”
- Background: Add depth with a lamp or plant; avoid bright windows behind you.
- Settings: Lock exposure/white balance in webcam software; use 1080p if available.
- Network: Hardwire with Ethernet or use 5GHz; close heavy uploads.
Result: brighter face, less grain, and a background that doesn’t blow out.
