I don't know what demosaicing is, but here's what I do know: The pic made with the istD and the 18mm lens was shot using the highest quality JPEG set at whatever the normal settings are for contrast, sharpness, and saturation, and received no further processing afterwards other than to be resized. The aperture chosen was the same for both lenses, 4.0 or 5.6 iirc.. The pic made with the 28mm lens was scanned straight and resized in PS. There was no sharpening or other adjustments used on the images except that a curves adjustment was used to bring the tonality of the images closer to one another.
