Tone Hacker by Guillermo Luijk

In this thread of the Luminous-Landscape you can find Tone-Hacker. A small utility developed by the spanish photographer Guillermo Luijk.
Tone Hacker allows any user to easily "reverse engineer" B&W tonings from his favourite authors, and apply them straight into any B&W picture. It also calculates a standard Photoshop .acv curve file.
This utility can be downloaded for free from the author's website (follow Software - Tone Hacker):
