Lighting and shadows in clinical posture photography
Bad lighting is a silent measurement killer. Fix light before blaming patients or software.
At a glance
- Diffuse key light from both sides when possible.
- Avoid single overhead spots that carve false valleys on skin.
- Re-test exposure after painting walls a new colour.
Soft, broad light reveals landmarks
Hard side light exaggerates skin folds and hides bony prominences. Use large modifiers or bounce flash into walls. Aim for even illumination across the full patient height in frame.
Mixed daylight and artificial light shift colour and contrast
If windows dominate one side, rotate the patient schedule or add curtains. Asymmetric daylight creates shadows that look like postural asymmetry.
How many credits does each analysis type use?
Fast, Standard, Advanced, and Dynamic analyses use different credit amounts—there’s a dedicated guide in this hub; Pricing also has plans and FAQs on monthly renewal.

Glossy tiles bounce light upward unpredictably. Mats can help but change stance height slightly—document mat use consistently.
When PosturalCheck operators should reject a capture
Train staff to redo photos when landmark zones disappear in shadow rather than forcing analysis. Garbage-in consumes credits and erodes trust.
