I apologize for not letting this matter rest, but I still do not understand... According to what I know, there are two major differences from a RAW file to a OOC jpgeg file. The first is that the RAW file needs some camera/sensor specific interpretations, which are taken from the input profile. The second is that the RAW file is linear, while the JPGEG file already has (standard!) gamma curve applied. A combination of (standard!) gamma curve plus input profile should thus give a natural image. If it does not, something must be wrong according to my knowledge. If there is a third factor, please explain what this is to me. I apologize if you think this thread annoying, I just wish to understand who is wrong, and where exactly the error is.
