Achroma

iPhone / Photo et vidéo

Achroma is a monochrome camera for photographers who see in contrast.

Built for deliberate black-and-white work, Achroma gives you a live monochrome viewfinder, classic composition guides, selectable lenses, and a focused shooting experience that keeps the image at the center. Shape the frame with rule of thirds, golden ratio, or rangefinder overlays, then capture the moment in clean, expressive tones.

Every photograph can be tuned before it is taken. Adjust shadows, contrast, exposure, grain, clarity, highlights, vignette, and toning in real time. Begin with crafted looks like Mono, Noir, Silver, and Ash, or create your own visual language with custom presets.

Achroma also treats the gallery as part of the photographic process. Favorite your strongest frames, filter by preset, search notes, group by date, and keep your work organized by numbered captures. Add voice notes with transcription, revisit location details, and export raw HEIC files or framed images ready to share.

For street walks, quiet studies, portraits, fragments, and everyday light, Achroma is a camera made for slowing down and seeing more.
