Doug: "Polar....then for extra fun, a Phil-o-Polar"
Yikes - that's Phil on steroids! - or is is Viagra? And that pucker looks a little worrying. I would have compressed the foreground a bit before polaring to remove that! Phil -------------------- ... because the Solar System ain't gonna map itself.

ElkGroveDan beat me on that comment.
The problem arises when you start to alter any part of one image, then you open the pandora box of speculation if anything you see in one image are real or if it have been altered in one way or other. And I dont talk about changing the colour (or even colourisation) making a 360 degree panorama out of a set of images of course. But as soon you move and copy a piece of rock or in this case sand, and present it as one actual image, then you really have gotten on loose sand. If theres something thats unwanted on the image it should simply have been cropped instead. |

All true But, we must admit they publish also all original images, both raw and pds... so you have the untouched material in your hands too!
Perhaps, for the purpose of a press release, these small changes are tolerable... -------------------- I always think before posting! - Marco -

They DID get the full pan out for the 1000-sol anniversary. Big pans are prone to little stitching artifacts and such, especially in the near field.
Try getting the Endurance pan perfect as an exercise:rolleyes: Nico -------------------- photographer, space imagery enthusiast, proud father and partner, and geek.

Yes, but when you have a gore in the image, you have another issue. It is even more unrealistic to look at an image with a big blacked out gore in it (or even a little one, for that matter), or to have areas missing a color filter appear discolored.

That faked section in the false colour McMurdo pan is certainly disappointing. They did a good job capturing the region in question on the natural colour pan, so it seems to me that they could've done a much better job of the false colour pan by matching the (false) colours as best as possible using whatever filters that didn't contain the shadow - heck, we've got all the filters here!
In other words, use whatever filter frames are available for the region in question. I'd say it's far less dubious to have some small region formed from different filters than the rest of the pan, and then colour matched as close as possible (this is false colour, after all!), than to paste in different topography! In fact, I'm willing to bet that many an imaging wizard on this forum could do a very good job matching false colours with the real topography... |

It appears that they used part of the deck pan to patch the true color panrama. As the deck pan was done in L456 rather than the full filter set it was probably easier to use it to match the true color image. The false color image, which likely uses L257 to get the maximum color contrast may have been more difficult to match. Or the images used to patch the true color image may not been transmitted yet when the false color panorama was stitched together.

In order thats MI, MI pulled away, APXS, Mossbauer. Cunning use of conjuncton time - big fat integrations on the dust capture magnets.

Spirit is bored from making all the images at the Winter's Haven and is now playing with her instruments. Uh, oh. There must be something related to this "issue". |
