Yet more from mars

Yeah, the horizon line does look rather unantialiased. If you zoom in, you can see that there is some antialiasing, but less than you would expect. The other weird thing is how monotone the sky is. There isn't any brightness gradient in the horizontal or vertical direction. (I checked and the sky is exactly 214R, 165G, 122B across almost the whole 360 degree panorama. There is a slight variation towards the top probably from the jpg compression and a small area in the southwest.) If you look at the sky on earth, you'll notice that it is fairly light near the horizon and it darkens as you look up - a brightness gradient. (Of course, we're not seeing very much of the martian sky in the picture either, so there might not be much of a gradient.) Or maybe they painted over the real martian sky to hide the flying saucers. :-D ------------------------------------------ Law of Nazi Analogies: As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches one.

I think all this is probably an artifact of the way the picture was assembled. I mean if you look at the ground, there are clear changes in colour where the picture has been stitched, so maybe the team simply decided that getting the shades of sky to look ok over the stitch lines was just to difficult, and so simply cheated - with the fill tool.

At the risk of provoking another pointless debate on global warming... The gradient effect you describe is a fairly recent phenomena, and is attributed (by some) to atmoshperic pollution. I believe historical records indicate (through artwork, descriptions, etc) that this wasn't always the case, and the sky, under normal atmospheric conditions, was more monotone.

Sorry to keep posting stuff relating to mars - but I do find it very interesting. Have a look at this image http://marsrovers.jpl.nasa.gov/gallery/press/spirit/20040113a/Horizon_hills_color-A11R1.jpg[^] This picture is about 7mb BTW. Amazing! But what surprised me is the horizon - look at it! It looks very unantialiased - I've never seen a digital photo that had jaggy edges like that. This all adds weight to my mars conspiricy theory; where NASA didn't actually send a space probe at all. They simply took the governnment money and spent some of it on a crack computer graphics team to fake these image, while the NASA finds itself $XX million in profit! Then again it could just be an artifact of how the mosiac was put together. Joel Holdsworth
LOL!!! You're really buying into this stuff, aren't you? Heck, they're filming just down the road from my house, off Silver Creek Road where Lauren and I went shooting last summer. They have to leave a guy out there at night to keep wandering burros away from the equipment, but he seems okay with that as long as we deliver the beer on time. I was down at the bar last night with a couple of the guys from the film crew, cutting and pasting photos together with cello tape for 'release' to the media today.:laugh: Yeah, we were a little toasted - sorry about the jagged edges. But they said they'll let me work the joystick this weekend (I had to buy a couple of rounds) - watch me do a loop with that sucker! Up and over... Wheeeeee!!!! Then maybe down a mineshaft. Until then, enjoy the 'Mars' pics!:-D "Another day done - All targets met; all systems fully operational; all customers satisfied; all staff keen and well motivated; all pigs fed and ready to fly" - Jennie A.

If you look at the photo, slightly up and to the left of the silver mast (left edge of photo), you will see a dolphin like creature, sporting an afro, and wearing sun glasses - must be a celebrity. :suss: :eek: Steve

It looks like they masked out the sky using a flood fill. But if it is a conspiracy, we need to create the CP Ganymede Rover mission with the guarantee that we won't have jaggies in our images!

Here's a quote about the assembling of the panorama (from Spaceflight Now): "In fact, being shown here is something that we assembled at one half the resolution and one quarter the number of pixels because the sheer number of pixels was slowing down our machine in getting it ready for you today." So, it's a rush job (with a better reslution picture promised in a few days) and throwing out 3 out of every 4 pixels would explain the aliasing.

You have good eyes! There was an old martian movie from the 60s that had the old Batman actor as the Captain of the ship that landed there. In the sand lived these shark like creatures that looked nothing like sharks but did look like the "dolphin" in this picture. It was on SCI-FI a while back.

Heh. I don't give that image much creedance. As easy as it is to work in advanced graphics packages like Lightwave and 3dsmax 5/6, one could EASILY bullshit up an "authentic" looking image. :suss:

Must have been a particularly smoggy year. :laugh: Of course, time of day could be a factor, too. Dawn or dusk (which may be the impression Da Vinci intended) would always produce a gradient effect, I'd imagine. No, I wish I could remember where I read or saw that. I really can't remember many details about it; I seem to remember something about photographs of the Grand Canyons showing the difference particularly well.

I will check your link out later when I can download 7mb without killing our line. But for now I found this Quicktime VR image: Fullscreen Mars panorama. Loaded snappily even for me and it is awesome, no jaggies either :) (Anybody who wants to give me grief about "Oh no, it is Quicktime" can redirect their hatred to Apple.
