The Problem: Digital Crop Modes Are Compromises
Cropping in post or menus mid-shoot both break the flow. zeta9.de moves the format decision physically before the shutter.
A Physical Tunnel Creates a Cognitive Tunnel
The haptic format choice before the shutter closes a feedback loop that continuously optimises for the predefined goal. At the same time, the top's tunnel blocks peripheral vision and creates a cognitive tunnel — focus narrows, load drops, flow emerges.
