I thought perhaps Aperture took a second to apply some in-camera processing to the image, but the only option I have turned on is ActiveD Lighting, which I am told has no affect in Aperture.
the opposite is true. When Aperture loads the images, you see the jpeg previews with the in-camera preprocessing, and afterwards the previews of the naked raw files generated by Aperture, without any adjustments done.
If you prefer the processed jpeg with in-camera adjustments, you might consider to use the jpegs as masters/originals and not the raw.
