It is quite rare for me to see that there is no choice but to publish significant amount of technical data to accompany these shots.
Both were made with K10D set to auto white balance, PEF RAW format. The lens was SMCP 50/1.2 stopped down to f/8, f/9 with -0.7 to -1Ev of exposure compensation. The time was around 14:20. During post-processing I only changed contrast and clarity as the original images were somewhat dull in appearance.
It was probably the most peculiar weather that I've witnessed in Israel so far.
