Know when the camera is still adjusting
White balance, exposure and focus sometimes need a moment. Opsino shows when these settings are still active. Wait briefly, hold your iPhone steady and measure again.
Improve the light or the surface
Very dark or overexposed areas contain little usable color information. Movement, several colors in the circle or a shade near a naming boundary can also trigger guidance. Opsino indicates when better lighting or a more even patch may help.
