Need a practical next step? Start with Body Fat From a Photo, then compare against How accurate is AI body fat estimation from photos?.
If you want broader interpretation beyond body fat context, run an AI Body Analysis App check-in using the same photo rules below.
The quick checklist below covers the highest-impact setup details for desktop searchers comparing photo guides: front, side, back, mirror selfie, camera height, distance, lighting, and relaxed pose.
Set up your photo protocol in 2 minutes
Use this checklist once, then reuse it for cleaner weekly trends.
Front, side, back, and mirror-selfie rules (quick checklist)
- Same lighting (bright, indirect)
- Same distance (mark the floor)
- Same camera height (mid-torso)
- Same angles (front / side / back)
- Same time of day (morning is easiest)
- Same relaxed pose (not flexed)
If you do only one thing, keep distance + camera height constant.
Front photo rules
- Stand tall with arms relaxed
- Keep full torso in frame
- Avoid low camera placement (distorts proportions)
Side photo rules
- Maintain neutral posture (don’t over-arch)
- Keep stance and foot placement consistent
Back photo rules
- Match distance to your front/side photos
- Don’t twist to exaggerate lat width
For lower-body tracking, keep one optional legs angle consistent:
Mirror-selfie rules
Mirror selfies are usable if you standardize setup:
- Use the same mirror and phone lens each check-in
- Keep camera centered and at consistent height
- Avoid dramatic perspective by standing too close
Shirtless male/mirror-selfie estimation notes
If your goal is to estimate a body fat range from shirtless male mirror selfies, keep these constant:
- same mirror
- same camera height
- same stance
- same lighting direction
Then compare trends over 2-4 check-ins instead of judging one photo.
Clothing, lighting, and distance mistakes
- Changing clothing fit changes visible definition
- Harsh lighting can fake leanness
- Small distance shifts can mimic progress
Treat each check-in like a controlled test, not a new photoshoot.
Use LeanLens with this setup
Once your setup is repeatable, LeanLens outputs become easier to trust:
- confidence context is more meaningful
- range comparisons are less noisy
- next-step guidance is easier to apply
