[X] My Assistant

[Nirgal]

Hi all,

just discovered NASA's top secret additional X-filter files for the hazcam.
So now I can do full color Hazcam-pictures
nah, just kidding of course...

Just like to share my latest colorizing project:
this remarkable view with the Eyes of Spirit creeping
up the Hill...
(thank god this did not become the good-bye-roving image for Spirit:
seems that we got free of the sand-trap again !)

hope, not too red this time

Wow Nirgal they look great. Just out of curiosity how long does it take you to colour an image this size

spent the last 2 days on it ... where large part of the effort was to write
further improvements of my special software that assists me in the
colorizing process.
It's all still very experimental at this stage ...
but the results so far look promising.
Unfortunately, without multiple filter bands it's still a lot of manual handwork
ad involves excessive fine tunig with hundreds of different color hues...

but it's a lot of fun nevertheless ...
reminds me of the fun I had as a child with colorizing the painting book.

Now Mars is the new painting book

Well, you certainly have a gift for it, Nirgal. We all realize that there is some artistic license in what you're doing, but I for one don't mind a bit.

If you really want to play with trying to make it look *exactly* like it would look to a human being standing on the surface of Mars, there is a nice discussion of the color hues of the Martian surface in the NASA publication on the Viking landers. I don't have the book anymore, but it was one of their SP- series. One section late in the book shows the same scenes with three different color corrections -- one as if seen in white light, one as if seen on the surface of the Earth (with the blue fill you get from the terrestrial sky), and one as if seen by a human being standing on Mars, with the low light levels and the orangish light fill from the Martian sky.

What you're doing right now looks a lot like a cross halfway between the first two -- white light and Earth lighting conditions. But don't get me wrong -- I really enjoy your vision!
