Frequently Asked Questions
How does the C-41 Color Negative Film inversion work?
True analog color film negatives have an orange/amber dye mask. Our C-41 engine subtracts the orange film base, normalizes the RGB channels independently, and inverts the tonal curve to produce accurate, vibrant positive photographs.
What is the Sabattier Solarization effect?
Solarization (the Sabattier effect) is a darkroom phenomenon where shadows and midtones are partially inverted while highlights remain positive, creating unique metallic halos along high-contrast boundaries.
Can I convert white scanned documents into OLED dark mode?
Yes! The Document Dark Mode preset converts blinding white pages into deep blacks while preserving sharp, high-contrast text and signatures for comfortable night reading.
Does inverting colors affect transparent backgrounds in PNGs?
No. The Preserve Alpha Transparency toggle protects transparent areas so your cutouts and logos remain transparent without turning solid black.
Are my images uploaded to any remote server?
No. All bitwise pixel calculations, color space conversions, and image compression execute 100% locally in your device browser RAM with complete privacy.
