Note: Please hold off on downloading this file for the moment; I accidentally updated an early version. A newer (better) version is on its way.

Fixed a problem with the intial upload.

New version modifies the limits of the sliders to [-1, 1] and indicates "clipping" (intensities <0 or >1). I removed "lightness" method, because it uses an approach that is inconsistent with other methods in the app.
