I have recently updated the site with some new mosaics and others to be followed but meanwhile I'm starting to get optimistic about the Everest Panorama. For now I'd like to share the fullres uncorrected panorama as I feel it's interesting in a way, though composed of raw images.


see AwalkonMars home_go 'progress on 360 panoramas'

or directly;

L256 false-color 100%

L2 red channel 50%
L5 green channel 50%
L6 blue channel 50%

there. Is it true color? Nope. Is the picture you took yesterday with your digital camera true color? Nope. L256 is 3 filters, just like your ccd- or cmos sensor is filtered by red, green, blue. An inboard algorithm makes color of that information. Different brands produce different hues, even through identical lenses and settings. I'm tempted to state that the 3-filter and surely L234567 color, when calibrated properly produces better true-color than any prosumer camera you're going to buy.

Take a look at an 'informative' sol318-325 pan I did;
Latest 360°
Notice the differences only a few hours of difference make. All right, saturation could be too high, as well as contrast. But still.

Now I started 'correcting' this Everest pan with quite some optimism but gave up. The Nasa/JPL version is a better approximation than my messy raw-pan( ) but we'll be glad when we get the calibrated data for this..

Mars' surface changes in brightness, color just like any other planet with something of an atmosphere.
When you have perfectly calibrated color-you want to make the entire pan look that way, ..you go changing brightness, in the separate channels. There's no perfect pan anyway - you have differing directions and darkness of shadows.
