Hi, emilio. Thanks for your interest in the photo of the Gum Arabic Tree. I myself was surprised by the yellow in the photo (the saturation was not touched, but I did take the photo with Canon's vivid colors option). The tree trunk, particularly when young, has a more intense red-orange color which you can see in the photo. The yelllow may have something to do with the angle of the light - that photo was taken pretty well at midday.

I'll keep my eyes open for photos of building reflections. I recall seeing one that impressed me on fotolog, but I can't recall the name of the flog.There's also an interesting church that reflects nicely in a glass building in a square not too long from here but I've never been able to photograph it to my satisfaction.

Jim
