Author 's note :
TU:19h00
Altitude du soleil: ~ +17°30
Traitement de l'image en niveaux automatiques suivi d'un léger rééquilibrage de la balance des couleurs.
Opération classique qui dégage le ciel de son voile réfractant, le phénomène et sa structure nuageuse, en une impressionnante 'profondeur'.

Une petite erreur dans l'heure:
TU: 17h00 et non 19h00

Adjust the brightness and contrast of your monitor so that you can see each step separately.
Pay more attention to the black steps here. The darkest step should be as dark as you can
make it while still being able to distinguish it from the next lighter step.
