Knobroom is a direct manipulation add-on for Adobe Photoshop Lightroom 3, allowing access to Lightroom photo development settings with a MIDI-controller.
Main motivation for developing Knobroom is improving ergonomics, which in the end will improve your creative workflow. Sliders are quickly accessible and easily adjustable without causing mouse-related injuries or stress on your wrist.
Currently Knobroom is in ALPHA stage, meaning it is not yet recommended for production use.
