I think most people today would opt for Adobe Lightroom CC—if they are not going for expensive stuff like Phase One. I´m using three steps: 1. Silverfast 6.6; 2. Adobe Bridge CS4, Camera RAW 5.0; 3. Adobe Photoshop CS4, First I produce a scan that picks up as much material from the roll as I possible can, then I use a combination of tools (things like CR: Basic, Sharpening/Noise reduction, Hue/Saturation/Luminance; then PS: Dust cleaning: Clone tool, Unsharp Mask/High Pass (Copy "Background" layer. Radius around 6 to 7 for a face; layer blending mode: Soft Light, often 67%, great sharpening filter used with care), Crop, Levels, Curves,Color Balance, Hue/Saturation etc) in the creative Suite 4 to get to my intended final result. Which might then look like this 100% screen crop of a 5120X4067px scanned TIFF:
