Interestingly, I was going to have a look on the PDS image catalogue these days. The Opportunity-pictures from Sol 616 are available now.

Using an similar technique as Mr. Harald Keppler (which was yelled down and the target of some childish jokes) some weeks ago, I got similar results: The R246- and R345-composites show distinctiv infrared colors which should due to a difference in chemical composition.

Another possibility would require a differential polarizing effect in optics and minerals, but I do not think so. I think, any effect due to time difference between the photos or glance refelction can be excluded. It is strange to see thes cobbles come alon in some changing appearance.

To make these pictures, the PDS-imagery was combined in photoshop as channels, then the saturation of the photo was increased by 80 percent and then auto levels to have more contrast in the picture. Nevertheless, the subtle color shading can be seen after the first step also without auto-levelling.

I am wondering about two special things:


1. Why was the Imager system of Cassini not set on a scan platform? I am really wondering that more than the half possibilites for RADAR-cartography are lost to do other experiments? This seems not an excellent technical solution.

2. Why was the Huygens camera build with such bad resolution? Also the "test images" done at the LPI parking area would give a lot of questions if people were not said that these things in the picture are trees.

Some experiments with a simple CCD-camera at 1/1000 of the illumination given on Earth shows clearly that better pictures could be done without problems, and there are better compression algorithms.

As the soviet space probe has shown during the 70s and 80s, it is possible to make panorama photos from a torrent surface during a flyby of the bus without serios problems.

I am really wondering on those funny self beloving of some ESA-"professionals" and the things told about these bunch of lousy photos they have gotten.

Some experiments with a simple CCD-camera at 1/1000 of the illumination given on Earth shows clearly that better pictures could be done without major problems.

I am working on that topic making cameras for supervision and examination for night and day.
