|Storm over Luskentyre - Leica S, 30-90 @ 30mm, f/8, 1/90s, ISO 100|
It looks to me like the one slider increased contrast (at multiple scales) and saturation. Interestingly, since increasing contrast changes tonal relationships, I would actually have expected this control to be up in the "Basic" settings area rather than down in Effects (with Vignette). I find dehaze to generally do a good job on most images, so its actually the first thing I want to try, and then go fix up the tonal relationships afterwards. I haven't tried going negative on many images but on the ones I have I almost always want the ability to do it selectively (i.e. with the radial filter or brush). Overall, I like this new tool and I think it should just be called "bacon" because a little bit makes almost every photo taste better.
