Seriously; if I look at the fascinating surfaces of some planets and moons in our solar system - I would not be surprise. :)

Alice, Alice ...? The Alice with the restaurant outlets in the Netherlands?
Well, that's very long ago. I fear she won't remember me... :wink:

But the topic is called "Post your Celestia pictures!"
Therefore; here's a picture from that time... :)

I'm no expert at such things, but I think that you want to make such photos you need to take advantage of the atmospheric effects in Celestia.

In your solarsystem.ssc file, add something like this to throw a copy of jupiter over the moon:

Code: Select all

"Jup:Earth II" "Sol/Earth"
{
   Texture "jupiter.*"
   HazeColor [ 0.4 0.45 0.5 ]
   HazeDensity 0.3

   Radius 71492 # equatorial
   Oblateness 0.0649
   CustomOrbit "moon"

   # Overridden by CustomOrbit
   # EllipticalOrbit
   # {
   #    Period           11.8622
   #    SemiMajorAxis     5.2034
   #    Eccentricity      0.0484
   #    Inclination       1.3053
   #    AscendingNode   100.556
   #    LongOfPericenter 14.7539
        #    MeanLongitude    34.404
   # }

   Atmosphere {
      Height 300
      Lower [ 0.7 0.6 0.5 ]
      Upper [ 0.5 0.45 0.4 ]
      Sky [ 0.8 0.8 0.5 ]
                Sunset [ 1.0 0.6 0.2 ]
   }

   # IAU rotation not used for Jupiter; it is based on System III
   # (radio emissions), not the cloud positions. In Celestia, we're
   # more interested in having the Great Red Spot appear in the
   # (approximately) correct place.

   OrbitFrame {
      EquatorJ2000 { Center "Sol/Earth" }
   }

   BodyFrame { EquatorJ2000 {} }
   CustomRotation "iau-moon"
   LunarLambert 1.0

   # Overriden by CustomRotation
   # UniformRotation
   # {
   #    Inclination    23.4608
        #    AscendingNode 359.9949
        #    MeridianAngle  38.3213
   # }


   Albedo 0.51
}



Then in Celestia, control time to rotate things to the time you want them (day or night, and phase of the Jupiter) and then use Ctrl+G to go to ground on the earth, and then look at Jupiter (or whatever) from the ground. Then save off a screen shot, and edit in the GIMP from there.

Here's my first attempt at it, seeing Jupiter in the sky above the Grand Canyon. Interesting to me that no matter how enormous jupiter is, if it's not lit by the sun, it's not there in the glowing blue sky. I'm sure other more talented people could do much better (like blending the clouds across the planet) but I think it demonstrates the promise of the technique.

You'll never see a planet or moon in the sky appear darker than the sky itself.

You also need to match the angles of illumination. In the picture above, the light on Jupiter seems to be coming from the upper right in front of the observer, but the light on the deadwood seems to be from almost straight overhead or perhaps even slightly behind the observer..

Ah thanks, good feedback, so one more quick hack at this. I didn't play with colors in the Gimp: just made sure that it was close to noon on earth when I captured the picture looking up at Jupiter... darkest stripe on Jupiter is now (RGB) 132,157, 214 and the blue sky near it is 90,149.207, so I think i fixed the brightness issue.

The angle of illumination is closer (right time of day) but not quite right (that's not where jupiter was in the sky). The way to get it right, I now realize is start with a picture which has the moon in it, then go that time and place in celestia, and everything will just line up automagically.

The stars were generated using Rassilon's generator, there are many planetary systems. The nebula is Rassilon's Rosetta, re-coloured on a new mesh.

My advice on placing Celestia objects in photos:

Take a screenshot of the desired object with nothing else surrounding it (eg, stars turned off), and if viewing it from the surface of a moon or planet, turn OFF the atmosphere rendering. Make sure the object(s) you are taking a screenshot of is surrounded by pure black.

Next, instead of cutting and pasting a selection, add the screenshot as a completely separate layer on top of the photo, resizing if needed.

Finally, look for the "mode" in which the screenshot layer is in. It should say "normal". Click on it, and you should see a list. Select "screen". The object should then look like it is being viewed through an atmosphere in real life, for the most part.

Experiment with the layer "modes" to find a setting you like best.

You're welcome. :)

Now for a new screenshot from me, 100% Celestia, and once again, I'm up to no good. :D

This was inspired by a dream I had, which kinda had a sad ending.

I also got a different cloud map, because I got tired of the Blue Marble one.
