Erhm, the film isn't neutral to begin with. So a pure white inversion, on a non-neutral image, will not give you a non-neutral result. If you use the colorpicker in the area between the negatives (resulting in green being subtracted) works fairly well (resulting in a reasonably neutral image). This is basically how the plugin is supposed to be used in the first place. And if you want a perfectly neutral end-result you'd need to keep the monochome plugin enabled at all times anyway. I've attached a style which worked well for me to illustrate. Regards, Pascal de Bruijn
