I currently use ACDSee Photo Manager 12 and Silkypix Developer Studio 3.1 SE for my PP. But each has shortcomings, so I end up using both. (Edit: Come to think of it, I also use Picasa for cutting video files from time to time.) As to Silkypix, it has no tiered exposure adjustment tool (a la the "lighting" tool of ACDSee). It only has the "contrast" tool, which doesn't let me bring only the shadows up or only highlights down. As to ACDSee Photo Manager, it doesn't let me adjust the white balance by choosing a specific color temperature like Silkypix. In addition, it doesn't process Panny's RAW format. So, in order to streamline my PP workflow, I think I'll buy a "pro"-version PP software. And since I'm going to invest, I'll also look into Adobe Lightroom. In my new PP software, I need the following criteria. RAW development for micro four thirds and canon (I have an S95) white balance adjustment by choosing a numerical color temperature "tiered" contrast adjustment (i.e., bring up/down only shadows, midtones, highlight) file name filtering (e.g., show only JPEG files, RAW files, etc. Picasa is really good at this.) very basic video editing tools (e.g., move start/end points. Picasa does this well.) Do any or all of Light Room, Silkypix Pro and ACDSee Pro fit the bill? If so, which one would you recommend and why?
