En ce moment, vous avez le privilège de contempler plusieurs planètes du système solaire au cours d'une même soirée.
Un alignement planétaire est assez rare car toutes les planètes doivent se trouver dans une même portion du système solaire et quand on sait que pour plusieurs planètes il faut des dizaines d'années pour faire un tour complet, on comprend mieux la rareté de l'évènement.
Ici j'ai capturé Mars, Jupiter, Saturne, Vénus. Uranus et Néptune sont également dans le champ mais non visible, il faut s'équiper d'une paire de jumelle ou d'un télescope et savoir où regarder.
J'ai recréer les trajectoires orbitales de chaque planète à la manière de Stellarium (Logiciel et app de cartographie spatiale). C'est cette trajectoire (nommé le plan écliptique) qu'emprunte les planètes dont la Terre autour du Soleil.

Sao Paulo has many classic modernist masterpieces. Most were build during the socialist spring in the sixties. An unique epoch -the dominant political ideology was perfectly aligned with the normative orientation of the Brazilian modernist architectural movement. It all ended with the ’64 putsch that plunged Brazil in a decades long military dictatorship.
On display is here the Copan building (1963) on the Avenida Ipiranga, Sao Paulo. It’s an example of the first phase of Brazilian modernism, has 32 floors / height 112 m, 1160 apartments, 5000 people. It is the biggest structure in armed concrete of São Paulo. The eye catchers of the building are the curved concrete brises soleil.
It’s designed by Oscar Niemeyer, though he left the project before completion. His design follows the lines and principles of the modernist philosophy , envisioning a place where people with different ways of living and cultural identities could coexist in harmony. To facilitate that, various areas for recreation and meeting were projected, such as as a cinema, a theater, a big restaurant and a hotel. Due to problems with the building permit and bankruptcy, the building process was halted for a few years and the project design modified - the hotel, the theater and the big family apartments weren’t realized.
A pic from a second phase (also known as “Paulista Brutalism”) modernist building in Sao Paulo by J.B. Vilanova Artigas is here.
The pics were taken at the end of a very long walk through the city which had filled up the CF card of the Canon. That meant that I had to use Fuji F30. As consequence I had to make do with only moderately wide angled shot. With the radical angles / framing on display here, I tried to compensated for that.
A pic of the Copan in its urban context is : here.
I was initially interested in aligning the crop lines in such a way that leads the eye to the windmill yet I was not interested in making the mill the dominant element. Once this was set up I waited for a suitable cloud formation that would draw the attention to the top right.
Le Lac de Siguret est un lac naturel d'origine glaciaire : il est posé sur le plateau qui domine le hameau de Siguret, et est entouré de champs cultivés, de prairies, et de sous-bois.
