Bulent, If I understand your question correctly, you want to know if there's a standardised way of tuning a raw converter to the specifics of a particular camera, and whether these settings are portable between different software. The short answer is no. Partly because softwares approach the issue in different ways, and partly because SilkyPix have, in my firm suspicion anyway, access to information in the raw files that other converters have not. Adobe Lightroom use "presets" which can include many types of processing, and can be applied to your images when you import them to your computer. For the "curves" tool you can tweak it manually, but there's also an option to choose between "linear", "low contrast" and "high contrast". I suspect the rendering you get as default in SilkyPix is "linear". Adobe also has a level of correction called "camera calibration" which address colour biases inherent in the imaging chip or the camera firmware. This too may affect the rendering of the tonal range. I know converters like LightZone and PhaseOne RawOne have different interfaces (though RawOne and Lightroom has a lot of common heritage). It's been a few years since I used either of them, and can't recall whether they can apply presets in bulk the way LR does. For SilkyPix (or Pentax Digital Camera Utility), some "preset" functionality seem to be built in, such as camera settings for highlight protection and shadow enhancement, or colour space emphasis in White Balance settings (eg. "landscape", "bright", "portrait" etc.). In principle, those functions should not be active when shooting raw files, but SilkyPix is able to read the camera settings out of the file anyway. It might be that SilkyPix' understanding of proprietary data gives it an edge in the processing.
