Achroma

Achroma is a monochrome camera for photographers who see in contrast.
See your image in black and white before you press the shutter. Achroma gives you a live monochrome viewfinder, purposeful composition tools, and complete tonal control while you shoot—so the photograph is made in the moment, not rescued afterward.

Compose with intention
