Confidence levels explained
Every observation includes a confidence level so you know how much weight to give it.
Step by step
- 1High — the two photos are well matched for lighting, angle and distance, and the difference is clearly visible.
- 2Medium — the change is visible but conditions differed, or the difference is subtle.
- 3Low — lighting, framing or image quality made a reliable comparison difficult. Retake the photo in your usual conditions and try again.
