About

Chroia

Read full description

A camera that reproduces risograph printing — multi-plate color separation, halftone dot screens, and intentional plate misregistration, rendered live in your viewfinder and applied in full the moment you press the shutter. SIX REAL PRINT PROCESSES * Riso Duotone — pink + cobalt ink plates, overprinted * Flat Screenprint — halftone-free spot color * Offset Newsprint — a genuine CMY rosette, vintage press texture * Photocopy — Xerox-style decay and scan noise (free) * Engraving — single-plate crosshatch * Mimeograph — blocky ink blotches Each one is a genuinely different rendering pipeline — not one filter with six color presets. EVERY VALUE IS A SLIDER Ink color, screen angle, dot width, and misregistration strength — nothing is hardcoded to a preset. Dial in your own look. LIVE PREVIEW, FULL PRINT AT CAPTURE The viewfinder shows a fast live approximation; pressing the shutter applies the complete multi-plate overprint — every ink plate, composited with the same intentional plate misregistration real risograph and offset printing has. FREE TO START Shoot with Photocopy at no cost. Full Unlock is a single one-time purchase ($5.99, not a subscription) that opens the other five mechanisms: Riso Duotone, Flat Screenprint, Offset Newsprint, Engraving, and Mimeograph. EVERYTHING ELSE YOU'D EXPECT * HEIC capture, saved straight to a dedicated "Chroia" album in your Photos library — no separate account, no cloud * The mechanism you shot with is written into every photo's own EXIF * English and Japanese from day one No ads. No tracking.
