Description

Image "bonus" de cet été, réalisée entre 5h et 6h du matin, sous un ciel voilé... et plus vraiment noir ! :)
Seule une image verte a pu être exploitée, les autres étant beaucoup trop mauvaises et altérant le rendu des couleurs. Pour contourner le problème, j'ai mélangé cette image unique avec une couche verte synthétique réalisée à partir des couches rouges et bleues (50/50).
Donc une petite image souvenir sans prétention ! :)

"Bonus" image made on 27th of August, between 5am and 6am under a veiled and no longer-really-dark sky !
Only one image for the green channel, too many defects on the others. I used a synthetic green channel made from red and blue channels (50/50), combined with the single real green image.
Just an image for fun (and test) ! :)
