Camera choice changes apparent density and recession. If you alternate between selfie and rear camera, you are comparing optics, not biology.
TL;DR
- Use one camera/lens setup and lock it for the full cycle.
- Rear main lens is usually more stable than selfie lens.
- Distance and angle control matter as much as camera choice.
- Consistency wins over hardware quality.

What to track first
- Select one lens and keep focal behavior constant.
- Use fixed tripod/phone support where possible.
- Mark subject-to-camera distance.
- Capture the same zones every session.
Decision checklist
- Did lens choice match prior captures?
- Is head tilt and camera height consistent?
- Are lighting and exposure comparable?
- If any setup element changed, flag that session as low-confidence.
Track-first next step
Start with a clean baseline and compare weekly captures in 4-8 week windows before changing your routine. Use the start path if you need the fastest way to build a reliable baseline.
