while a 'raw' pan, this should provide a somewhat more realistic perception of the scene....


What's more realistic in terms of what a human on Mars would experience, an "enhanced" color version or a "accurate" black and white shot?

The rift between artistic license and what's "real" can be a distant one. Here's my revised attempt to bridge the gap:


Your colors are very nice!
But maybe you could move a "sun" a bit on a left, even behind the edge, so the shadows on the left would look more natural...

In re the truly lovely images of Husband Hill from Spirit's winter quarters:

Very nice, but not quite right. The automatic gain compensation of the imaging processes (stretching contrast, etc.) has rendered the extremely relatively dark El Dorado / Ultreya feature to be the same albedo as the surrounding, much brighter, hill and valley.

This would be a *perfect* image if El Dorado / Ultreya appeared as dark, in relation to the surrounding terrain, as it should be.

-the other Doug


This is my attempt at a "near true color" composite, using the Sol 811 R7 R1 filter data (with a synthetic green channel mixing 50% red 50% blue) and partly enhanced / synthetic sky.
Fortunately, the Sol 811 pancam data seems to be complete now (without the missing data rectangle in the
dune-area of el-dorado)

here is the half-resolution JPEG; full res available on demand (running out of web space ...)

Very nice, Nirgal! People might be confused though: that is the daytime mosaic, and then there is also the sunset mosaic. Are you going to do the sunset mosaic too? And then a nice animated GIF switching between the two? The last should only be, oh, 34GB large in full resolution ;-)

As for the sunset panorama we already have those wonderful breathtaking b/w colorization interpretations done by Dilo, Aldo & Nico ! smile.gif

As far as a multi filter "near true color" version for the "sunset pan" can not be done from the Sol 813 data alone, because we only have one filter (R1 or L7) per camera eye ...

However, I tried to combine the color-only information of the R7R1 day time panorama taken on Sol 811 with the illumination-only information of the b/w sunset pan (separation and recombination of AB-channel and L-channel of LAB color space)
in order to colorize the sunset panorama: here is the result



(I deliberately kept the overall illumination low as to preserve the original darkish sun-set mood)

Here is a detail crop of the interesting dark dune pattern:



edited: if the color of the dunes appears too bluish (wich is probably due to the individual contrast stretching of the uncalibrated JPL JPG's) one could further reduce the blue
color channel in the final images ...

To eliminate any confusion -sol 813 false-color R1-7 using synthetic green;



edit: looks like we're having another pano-party tongue.gif

Congratulations, Nico: this must be the best Version of all (incl. full resolution and straightened horizon, simply perfect work !)

smile.gif smile.gif

How nice that good old injured Spirit, even in Winter rest, still gives us "fuel" for such great panorama parties smile.gif

One Question: Did you also use the combination of Sol 811 color and 813 illumination data ?

Thanks Nirgal, indeed an injured rover won't stop us -as long as the cameras work...

I didn't use the combination of sol 811/813 data. I will try it out though -but right now I'm awaiting my pizza delivery laugh.gif

What I like about your latest is that you kept the illumination low -and the 'mood' in the color range is very inspiring!

Spirit surrounding scenery has a bomb of very nice images and looks forward that the next time the Oppy's scenery site will too have ones nices when it approaches to any anomally tall ripple (soon) or close to a small crater previous with bright albedo to VC and VC itself.

These panoramas are indeed all excellent - but all suffer from vignetting, which is made more obvious when the individual frame edges are visible in the sky. Could I suggest a further refinement might be to dodge and burn a few selected areas just to tie everything together?

I've done a quick and dirty example!

You are right Bob and your quick & dirty example sure is improving the result.

It must be said though that thanks to Michael's anti-vignetting tool a great deal of vignetting has probably already been compensated for.
If anyone is interested in further improving my version, feel free to mail for a layered .psd file for download.

I'll probably wait for the calibrated data to give it another go.
