Light Scope - Lux Meter vs ColorHints Mosaic Usage & Stats

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.

ColorHints Mosaic

Color Hints Mosaic creates a mosaic or pixelated version of a photograph. The mosaic you create can be shared with others, saved, or printed. To create a mosaic, simply - take or choose a photograph - choose the tile shape, the number, and aspect ratio of the mosaic tiles - select the Mosaic tab to see the results Too many colors in the mosaic for your purposes? Just tap the “Limit” button and then adjust the slider to choose the number of colors that does suit your purposes. Or, use the Mosaic editor to choose exactly the colors you want – including using a palette to assign colors to the Mosaic. Create mosaics to use for - pixel quilt designs - pixel quilt designs - tile patterns - knitting patterns - cross-stitch patterns - beading - mosaics from glass, wood, or other media - minecraft art - posterization - student art Want to share your mosaic? Share directly from Color Hints Mosaic via social media or Air Drop, save it to iBooks as a pattern, or send it to another App, like Color Hints or QuiltSandwich (from NNN Software). Want a printed copy? Print your mosaic as poster as large as 200" (500cm) on a side. Or, print an annotated version of the mosaic complete with a table of colors.
