When I open up a RAW file shot with a Canon Rebel XTi in ACR, am I seeing the RAW data with the in-camera processing done to it? I read that the in-camera options are stored in a "header". Is there any point of applying an in-camera sharpening, contrast boosting or saturation when shooting in RAW? I did a few shots in the camera's default Picture Style and a few shots in a custom picture style where I turned the sharpening, contrast and saturation all the way up. On the camera LCD, the default Standard picture style shots looked normal, while the custom picture style shots looked way over saturated. However, when I opened up the shots in ACR, all of them looked the same. The oversaturated shots didn't look oversaturated anymore. Why does this occur?
