The best known quote by Socrates “I know that I know nothing” describes my attitude to Sigma Photo Pro very well. Just when I think that I know the RAW converter by heart, I discover something totally new. 😉 For instance, I haven’t paid any attention to the sliders “shadows” and “highlights” for a very long time as their effect is totally different than the effect of their equivalents in Lightroom. However, as I’ve recently found out, there’s also a reason why these sliders exist. Only you shouldn’t make the mistake of trying to darken or, respectively, brighten up or restore the highlights. As is generally known, crushed shadows and blown highlights are best handled with the sliders “exposure” and “fill light”. With “shadow” and “highlights” sliders, however, you can set the contrast and the saturation in a way that images appear similar to slide film. I’m sure you can also achieve similar results with Lightroom, but not as quickly and easily as with these two sliders in SPP.
