Subject: Luna in False Colour
|
Dear Group,
With clouds being the norm the past few days, I decided to sit down and
pursue something I had in mind for some time, namely a false colour
version of the full moon where subtle colouration is emphasized during
digital processing so as to bring out features of the lunar surface
which have a geological theme.
Using my photo of the apogee moon early last month, I have produced the
following false colour image of the moon:
http://www.perseus.gr/Astro-Lunar-Scenes-False-Colour.htm . The deep
blue colour represents areas on the lunar surface which are rich in
titanium and which are believed to also hold oxygen which is significant
if colonization is to occur at some point in the future. In contrast,
orange areas are completely devoid of titanium.
I think Felepe Alves was the first to pursue this technique and, unless
I am mistake, he also had a brief article in S&T describing his technique.
Clear skies!
Anthony.

It's not really false colour though is it? It's enhanced real colour.
The methodology is explained here - http://www.colormoon.pt.to/

You could find a job promoting more positive perceptions of let's say
certain types of cosmetic surgeries ;-)

Tell me all about the axial tilt of the Earth,the analemma and the
Equation of Time -
http://www.perseus.gr/Astro-Tips-Analemma.htm
I loathe using Huygens work to counter this late 17th century
'analemma' junk but the alternative is far worse for humanity -
http://www.xs4all.nl/~adcs/Huygens/06/kort-E.html
If I can stand the indignity of celestial sphere astrologers running
amokj with the great Western insights then you can suffer the original
core principles that never mention the analemma,a figment of somebody
else's imagination.

Excellent, as usual, Anthony.
I have two questions: In your digital workflow, why did you convert to TIFF
at the start, istead of manipulating the RAW and finally converting to JPG
for the web?? and second, why is there such a pronounced orange-ish cast to
the image??

George,
I realize that we can import directly into PS CS2 and this is something
I have done before. Just a matter of (bad) habit to convert to TIFF
first with this particular example.
Anthony.
