DOCUMENTATION

This module allows to invert scanned negatives and simulate their print on paper, based on Kodak Cineon densitometry algorithm. It is better than the old invert module because it takes into account the Dmax of the film and allows white balance adjustments, as well as paper grade (gamma) simulation. It also allows density correction in log space, to account for the exposure settings of the scanner. Finally, it is applied after input colour profiling, which means the inversion happens after the scanner or the camera got color-corrected, while the old invert module invert the RAW, non-demosaiced, file before any colour correction.
