How to take comparable progress photographs
Control angle, distance, expression and lighting so weekly images support honest implementation review.
Use the same three views
Capture front neutral, left three-quarter and right three-quarter. Keep the camera at eye level and use the same lens when possible.
Match distance and framing
Use the previous-photo ghost overlay and align face size and center position. A closer camera changes visible proportions even when the person has not changed.
Treat lighting as evidence quality
Face the same diffuse light source. Large brightness, shadow or color-temperature differences limit any visible comparison and should be disclosed.
Measure implementation, not attractiveness
A weekly report can describe completed actions, routine consistency and whether a chosen styling direction was implemented. It should never produce a beauty percentage.
