Description

Salut à tous ! 
Voici l'image qui jusque là m'a donné le plus de fils à retordre au niveau du traitement !! ce n'était pas une sinécure... près de 30h de photos et autant de traitement...
mais je suis plutôt satisfait du résultat ! on dit qu'on progresse à chaque photo, je le pense, et j'espère m'améliorer encore de longues années !
bon ciel à tous !

Hi all !
Here is the image that so far has given me the most problems in terms of processing !! it was not an easy task ... nearly 30 hours of photos and as much processing ...
but I'm pretty happy with the result ! we say that we progress with each photo, I think so, and I hope to improve myself for many years!
good skies everyone!
