You hit the nail on the head! Exactly — it’s a hardware-software bridge.Nack doesn't just 'add a filter'; it uses the flash as a calibrated light source to measure surface orientation.

It's the best way to show how Nack extracts 16-bit depth that is invisible to the naked eye in a standard photo.Thanks for the insight, it really helps to refine how I present the tech!
