Ooooh!.

I was brousing the last 500 "raw" images and spotted an overexposed F-ring shot with a trace of G-ring, so I contrast-stretched it to see more.. there was something in the foreground...

Then I decided to contrast a badly auto-contrast stretched Saturn nightside image.

In the well exposed images in this series, the midplane of the E-ring appears DARKER then the ring just above and below the midplane. Beyond this bright zone of the E-ring that I presume is at Enceladus' orbit, the ring brightness descreases, but this dark centerline disappears faster than the ring fades. To the left, towards Saturn, the ring brightness drops somewhat, it doesn't widen, so we're nearly in the ring plane..... and the faint dark band pretty much disappears! "Go Figure!"

Stunning images, apart the "quantization" artifact... so I worked on them to have smoother realistic gradients.

Enjoy!
