Very "raw" thumbnails 3D view...
Needs work but boy, just... beautiful... And have to say a HUGE "thank you" to the MSL team for taking and sharing the pictures with us. -------------------- |

Very "raw" thumbnails 3D view... Can't wait for the 3D view. It's going to be quite a challange to stitch it up, headache free. I expect some projections will work better than others in stereo.On another topic, isn't it remarkable how similar in colour the top surface of the HGA appears to the Martian soil? That could be relevant to the colour discussion in the other thread. But in the pre-launch views I've seen, eg: http://photojournal.jpl.nasa.gov/catalog/PIA14131 http://photojournal.jpl.nasa.gov/catalog/PIA13308 the colour looks much lighter. Maybe the HGA was covered in a different material before launch? |

Great work mcaplinger and MSSS! Can we assume that this is a best current cut of what the Gale environment near noon would look like with our own eyes, then?
... Maybe the HGA was covered in a different material before launch? I wonder if the Hi Gain antenna surface isn't somewhat reflective and the angle is giving us a bounce toward the mountain color. The antenna pre-delivery and photos in this technical paper seem to show different colors depending on the environment. |

Can we assume that this is a best current cut of what the Gale environment near noon would look like with our own eyes, then? No way, nor do we represent it as such. This is raw camera color and then whatever the hugin level matching did to it, with a big patch of fake sky. If you look at the raw frames you can see the exposure was all over the place, each frame was autoexposed. All that said, the rover body came out pretty white so I don't think the color is too far off. I'd have worried more about that if we had more time, but it took a while to get all the tiepoints right. BTW, the idea for the self-portrait came from my colleague Mike Ravine, who also did all of the hugin driving after I gave him the blemish-removed, desmeared images. -------------------- Disclaimer: This post is based on public information only.

I would love to see you and your colleagues' attempts at revealing the true colors of Gale as you characterize the cameras and integrate the global lighting effects as you've analyzed them. If that is one of your interests with the data, please let us know if ever such an image (or images) is (are) released. It is remarkable to get your perspective on this mission as you and your colleagues do the work. Thanks for sharing it! |
