Originally posted by blue birdThe image on the left was taken shortly after or during such a storm and the diffuse light with almost no
shadows is visible. In contrast to this, the image on the right, shows sharp shadows and clear blue sky, the normal condition on Mars.
Well the one thing I have noticed is that while NASA shows the "red", those that try to convince us that the sky is "blue" do exactly the same
thing NASA does, only in the other direction...
Image one is clearly adjusted to show the darker red that NASA likes, while the other one is so clearly enhanced to the blue side that everything has
a blue tint.... so neither image shows true color
What is more than interesting is 'red' sky - but that was not the case back in '76 as we can see from Viking images - original data no
corection!!!
Only problem with that is that the Viking Rover shown in your image is blue as well... but it is really WHITE...
Now then I too have a Mars Color image....
The image below taken by Spirit Rover is one from NASA and is "Radiometrically Calibrated" This image represents true color on Mars. These images
are not generally released to the public yet are not difficult to find. However for the time bring you will have to track them down yourself as we are
not ready to hand over this source just yet...
Now I have done field work in geology for most of my life and the bluish black rocks and the sand in the image below look just like the volcanic
Scoria, a type of Basalt in the desert sands here in Nevada... This summer I will go and take some photos of the area so we have a direct
comparison.
In the meantime below is a small sample of Scoria or Vesicular Basalt. You can see the bluish black natural color of this material and it is readily
found on Earth as one of the more common lavas...
This gives me a pretty good reference to be able to see that the image above is indeed true color on Mars...
Now the image below...
Mars or Earth... you decide...
