Also, watch out for the optical illusion that a gray material will look green when surrounded by a red material. I checked the RGB values of that "green" material and it's actually brown or orange (R and G roughly equal but R always greater than G, much lower blue), it just looks green by comparison to the bright red dust. I would not recommend attempting to determine mineralogy from Mastcam photos. You can tell dust-covered surfaces (red) from less dusty surfaces (gray, blue, or green-looking), and you should be surprised by stuff that looks white. Some rocks appear to have different colors when compared to each other, but that's about as far as I'd go in interpreting color. I would certainly not guess at mineralogy.

Zelenyikot: nice work!

Zelenyikot
yes but ChemCam doesn't do color.
You just make it look like it does.
So the amount of green depended on you're method which would reflect on the reason for making it, which just so happens to fill a void .

So do you think it's olivine?

Actionman, I did not invent color. Color pictures taken from the Mast camera. I would not want to speculate about types of stone. NASA zap the 'Stonehenge', so I suggest to wait for the release.

Here is my take on a Glenelg panorama from Sol 64. I realize that the data for the nearly full 360 degrees is available now, but at the time I stitched this together, this is all that was available.

Zelenyikot, very nice work. I really like the Chemcam images with Mastcam colour. That was an excellent idea.

Thank you. I am glad that I can at least thus join the great cause of Curiosity and your feedback is very important to me. I will try to continue in the same direction rolleyes.gif

What do you like smile.gif

Colored ChemCam from 71, 77, 79 sol. And ChemCam anaglyph ( trial).

P.S. Good day to you today.

Thanks for the coloured chemcam shots.

I don't think there's any real stereo in your chemcam anaglyph - the rover would need to move between the frames to get a different viewpoint. There are differences between the two frames, but I think they're just due to the moving shadows and to differing optical distortions across the field of view (since the pointing has changed between the frames).

In principle the viewpoint does change a bit as you change the pointing, but chemcam is pretty close to on the RSM axis, so the effect should be very small.

I was wondering as well how you generated the anaglyph.

fredk, yeah, I just tried. This two consecutive shots ChemCam. The camera does not move.



MAHLI anaglyph for 89 sols. New bright obоects smile.gif



P.S. I look forward to when MSL will hit the road. It seems to have all the Rocknest investigated smile.gif

Nice shadow reduction Zelenyikot - a part I somewhat failed on rolleyes.gif

Imprint of the APXS - sol 88:

I wonder if they did aim for the bright particle which looks like mica?
