Technical Specifications & Best Practices
- ✓When brightening a dark photo (e.g. 115%–130% brightness), also increase contrast slightly (105%–115%) to prevent shadows from looking washed out or milky.
- ✓For smartphone photos of paper receipts or text documents, boosting brightness to ~125% and contrast to ~140% dramatically improves OCR and print legibility.
- ✓Avoid pushing brightness or contrast past 160% on standard photographs, as extreme values can clip pure white highlights or crush shadow details.
- ✓All tonal adjustments run 100% client-side in your browser with zero file uploads.
