Auto exposure values for the same scene whether saving as JPG/TIF or RAW will be uniform. The difference is that the camera uses a prescribed formula to determine how it will process the RAW data captured to produce a composite JPG or TIF file based on solely on the in camera contrast setting and colour space. In the RAW process the photographer makes visual decisions as to where the optimum highlight/low light clipping lies and where the mid-tones are placed. > I guess the most important thing I got from your response was that the > histograms of the same scene, shot in Raw and JPEG will be different. Definitely correct and if you cycle through all the available colour spaces in the PS PCR convertor you will see the histogram change accordingly. It's worth having a play with even if you can't yet adopt a RAW work-flow as you main modus operandi.
