I have noticed that C1-5 always seems to place the darkest point in a scene at 0 on the histogram, even if it is not true black in the RAW file. I know this to be true, because in Lightroom, the same point may be somewhere above zero. Is there some way to change this behavior? I have found in Preferences under Exposure something called "Shadow & Level Pickers," but there is no explanation as to what they are for or how to use them.
Having the darkest point always set to zero limits one's ability to deal with shadows, and I would like to be able to have more control.
