Exposition Mars la Rouge à Grenoble - RdV le 3 mars !

Depuis le 18 février, et jusqu'au 14 mars, j'expose mes photo-montages de Mars à la libraire Arthaud à Grenoble (23 Grande Rue), sous le titre MARS LA  ROUGE, en référence au livre de Kim Stanley Robinson sur lequel se base mon imagerie de la planète rouge.
NOTEZ BIEN : INAUGURATION LE 3 MARS  DE 16H A 19H. Ce sera l'occasion de se rencontrer sur place !
Pour me suivre sur Facebook, c'est par ici !

Since february 18 until march 14, I exhibit my Mars photomanipulations at Grenoble's bookstore Arthaud, under RED MARS title, refering to Kim Stanley Robinson's book on which all this art is based.
The public inauguration of the exhibition will be next monday, march 3 from 4pm to 7pm.

The Space Elevator to Mars - Descent At Dusk

About 40 hours of work on this massive photomanipulation, made in high definition. I first built a 3D model (in Blender) of the whole area thanks to NASA topographic data (MGS MOLA), set the correct light and then photo-manipulated it carefully in Gimp, adding layers of color map (Viking) and high definition texture map (MGS MOC), plus adding the many details. The cable of the space elevator is also a 3D model.
So, we are in a travel cabin, descending along the cable of the space elevator, descending to Sheffield, the spaceport located on top of Pavonis Mons (the central volcano on the image). The time at the surface is dusk, and several large cities are appearing in the dark.
This image is entirely inspired by Kim Stanley Robinson's Mars Trilogy.
As always, made 100% open-source on Linux-Ubuntu, with Blender and Gimp.
I'd like to publicly thank Daniel Macháček for his fundamental help in the making of this image, as he taught me how to use the NASA data sets in the best way available. Whithout his help I doubt I would have been able to bring that realism in this picture. Please check out Daniel's astronomy photo-mosaics blog :
I want also to thank NASA and USGS for the wonderful and free data made available in such a cool way.
I mostly used MapAPlanet

Finally, let me recommend you the excellent website, where you'll get to know everything about KSR's books, past, present and upcoming. A site worth following, on FB and Twitter too !

Olympus Mons awakens

Another photo-manipulation that I just made.
This is the famous Olympus Mons seen from orbit as it is erupting gloriously.
To make this picture, I started with a 3D model (on Blender) : with a grayscale height map of the volcano (NASA data) used with the Blender's "displace modifier", I had a realistic setting of the light on this massive geology. I then rendered the lightened 3D model and photo-manipulated it (with Gimp) to add several light effects, the clouds layer and many improved textures (especially the caldera).

All made on Linux-Ubuntu.

Enjoy it in HD on my DeviantArt gallery ! (click twice on the image to see it in full details, especially the caldera)

In KSR's Mars Trilogy, there is no eruption on Mars, but I thought such mystical scene deserved a graphic try ! ;)
