Bleg: Canon & Apple RAW processing

I’m having a camera issue that’s become more and more noticeable with recent software changes. The raw previews coming out of the camera appear substantially more exposed than when Aperture is finished processing them. The difference is hard to measure (there’s no easy undo for raw processing), but appears to be about a full stop of light, sometimes more. I often use a quick shoot-adjust-shoot loop that gives me the exposure I want, and Aperture is messing with the result.

The intuitively obvious search terms (aperture, raw processing, exposure) are not getting me very far in understanding what Aperture does to process the raw images, how I might alter the defaults (well, there’s adjustments pane>RAW fine tuning, but that offers up only boost, huge boost, sharpening & edge adjustments, Moire, Radius and De-noise. Those don’t seem to be incredibly relevant to the brightness of the image.)

Does anyone have advice for how to get the RAW images to process differently?
