Six negative modes — pure 35mm invert, cyanotype, blueprint, X-ray, darkroom red, sepia negative. Intensity slider for half-strength blends, contrast control. Nothing uploads. For real cyanotypes, buy paper and a UV box.

where flipped colors land
for 35mm look
Pure Negative mode flips colors the way a real 35mm film negative does. Use it as the artwork for a music release, a band poster, or to demonstrate the analog aesthetic. Pair with Film Grain at low strength for the strip-of-film feel.
for botanical
Cyanotypes (Anna Atkins, 1843) are the OG blue prints — silhouettes of plants on UV-exposed paper. Run a flower or fern photo through Cyanotype mode and you've got a digital version of an Anna Atkins specimen plate. Print on watercolor paper.
for plans
Blueprint mode pushes everything toward deep blue with white linework. On a sketch, line drawing, or hand-drawn floorplan, it produces an authentic engineering-blueprint feel. Frame for a workshop wall.
for medical aesthetic
X-ray mode produces a high-contrast B&W invert — bones-and-shadows feel without an actual X-ray. Useful for medical-themed editorial, horror movie posters, or designed visual metaphors of 'see-through'.
for drama
Darkroom mode tints everything red, mimicking the safelight under which black-and-white prints are developed. Layer over a portrait for a moody, photo-school-aesthetic shot. Good for creative-process content (behind-the-scenes of an artist's work).
for art
Sepia Negative mode inverts and warms — looks like a damaged tintype or a botanical-illustration negative. Great for journal-page art elements, scrapbook backgrounds, or atmospheric mood-board pins.
in case you're wondering
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.

OpenFor real cyanotypes →
Real cyanotypes are made by coating watercolor paper with potassium ferricyanide and ferric ammonium citrate, exposing under UV (sunlight or a UV box), and rinsing in water. Permanent, archival, and astonishingly blue. About $30 in chemistry to start.
