## Description

A print you would frame, and the negative to make a real one. Seven cyanotype looks, real print sizes, and a digital negative for contact printing. No subscription.

Cyanotype turns any photo into a blueprint print: the deep Prussian-blue, sun-printed look of the original cyanotype process, on paper, with a matte if you want one. One look, done properly — plus the tools a real cyanotype printer uses.

THE PRINT Pick a photo and watch it develop: the pale coated sheet turns to Prussian blue the way a real print does in the wash. A darkroom pipeline maps your photo's tones between deep blue and paper white, with film grain, a hand-coated paper wash and a soft vignette. Press and hold to compare with the original.

SEVEN LOOKS, LIVE ON YOUR PHOTO Classic · Deep Sea · Sun Print · High Contrast · Faded Archive · Night Blue · Tea toned (the tannin toning printers do with tea). Every preset is a thumbnail of your actual photo, so you choose with your eyes.

MAKE IT A PRINT
• Print sizes: free, square, 4 × 5, 5 × 7, 8 × 10, cropped to the paper
• Matte borders in three widths
• Tone, Grain and Wash sliders
• Save a look and apply it to the next photo with one tap

THE DIGITAL NEGATIVE For people who make real cyanotypes: export your photo as a full-resolution negative, inverted and mirrored for contact printing on transparency film. No calibration curve is applied. Your chemistry, your curve.

Full resolution on export, saved to your photo library or shared anywhere. No account, no subscription, nothing leaves your phone.
