This tool lacks a proper calibration method
This tool does what it says, but measurements might be completely wrong if you don’t know how to calibrate it. It should have instructions on how to calibrate the cameras to collect accurate measurements.

Описание
LightScope is a comprehensive solution providing professional light measurement and analysis using your device's camera sensor.
【Key Measurement Features】
• Illuminance (lux) Measurement: Calculates accurate illuminance by analyzing EXIF data from the camera sensor. Illuminance is derived using the formula: (F-number² / (Exposure Time × ISO)) × Calibration Factor.
• Luminous Intensity (candela) Calculation: Automatically calculates the luminous intensity of a light source based on the set distance. Uses the formula: Illuminance (lux) × Distance².
• Color Temperature (K) Analysis: Precisely measures color temperature in the range of 1500K~15000K by converting RGB values to XYZ color space using McCamy's formula.
• Real-time Histogram: Visualizes the balance of shadows, midtones, and highlights through 16-level brightness distribution analysis.
• Contrast Ratio Measurement: Evaluates the ratio between the brightest and darkest parts of a scene according to WCAG accessibility standards.
• Noise Measurement (SNR): Calculates the signal-to-noise ratio in dB to evaluate image quality in the shooting environment.
【Advanced Features】
• Image Capture and Storage: Captures camera images at the time of measurement and stores them with measurement data.
• Full-screen Image View: Zoom, pan, and rotate captured images for detailed inspection.
• Gallery Saving: Save captured images to your device's photo library.
• Measurement History and Trends: Save all measurements chronologically and visualize trends with graphs.
• Camera Full-screen Mode: Hide panels to focus on the camera view while checking key measurements via a mini info panel.
• Perfect Dark/Light Mode Support: All UI elements automatically adapt to the system theme.
【User Settings】
• Illuminance Calibration: Adjust the calibration factor for more accurate measurements based on your environment.
• Distance Setting: Set the distance to the light source for precise luminous intensity (cd) calculations.
• Front/Rear Camera Selection: Choose the appropriate camera for your measurement situation.
【Technical Features】
• Support for measuring various light source types: natural light, LED, fluorescent, incandescent, etc.
• Algorithm optimization for stable color temperature calculation even in low-light environments
• 10-frame moving average filter for measurement stabilization
• Center-weighted image analysis for accurate evaluation of main subject quality
• Automatic exposure quality assessment based on histogram analysis
Perfect tool for photographers, videographers, lighting designers, UI/UX developers, and anyone who needs accurate light measurements.

가이드가 없어서 어려워요..
측정중에 카메라 줌을 땡겨서 확대하니까 폰과 측정거리는 똑같은데 조도값이 엄청 상승하네요.
오 업데이트 멋집니다
개인적으로 조도 측정기를 구매했는데 오차가 얼마나 나나 볼게요
