We present two versions of the ToneZone tool, which allows users to explore image tone ranges. The original ToneZone tool is a dual-mouse, dual-cursor tool, while a modified version requires only a single mouse and cursor. Both tools are designed to encourage non-experts to explore the powerful interaction of tone range manipulation.
