Flip the colors. Print blue.

No. The pixel inversion runs in your browser. Your photo never touches our servers — we don't run an image pipeline at all.

Duotone maps photo luminance to a two-color gradient (any two colors you pick). Photo Negative inverts colors first, then optionally tints. The starting point is opposite: Duotone treats the photo as tonal info; Negative treats it as color info to flip.

A photographic process from 1842 — coat paper with iron salts, lay an object on top, expose to UV light. Where light hits, the paper turns deep cyan; where the object blocks light, paper stays white. This tool fakes the look digitally.

X-ray mode strips color entirely — it converts the inverted result to luminance-only and crushes contrast. That's the point: real X-rays show only density, not color. For a tinted invert, use Cyanotype or Darkroom modes.

Blends the inverted result with the original. At 100%, you get pure inversion. At 50%, half-and-half — the photo looks faded and surreal. At 0%, the original photo passes through unchanged.

Yes — JPG export at full source resolution. Cyanotype and Blueprint modes print especially well on cream paper (the slight off-white softens the deep blue). Pure Negative prints best on glossy photo paper for that authentic 35mm-strip feel.
