Wow Amazing pictures. My usual questions when seeing such picture-quality: Did you use some special whitebalance-settings and diffusors (like an umbrella)?
@ Gerald: I always use Auto White-Balance, but Sony is known as very good for this. In case of problem, I always work with raw files. I don't use diffusors but I often use my flash even in sunny conditions.
What a great trip it must have been, I recognize some places and makes me dream about going back..... Great shots and great findings. I have to spend some more time arround Oukaimeden, I missed the viper and the Timon because I was there during the hottest period of the day. Well done Matthieu
