  • Comparison of high-end tele zoom lenses

    During my recent safari in Kenya, I got the occasion of seeing some of the best tele-zoom lenses in action (I was the one with the smallest photo equipement).

    All inkjet papers were not born equal. For example, their surface can be varying a lot from one paper to the next. Maybe, you thought that the only difference was in the weight of the paper, whether it was glossy and its price. Oh boy! Were you wrong… As a matter of fact, paper manufacturers…

  • Nuclear war in Iran in 2006? It’s gonna flash!

    In a private circle, I had made the prevision that the United States of America would initiate a military action against Iran in 2005. Time proved I was a poor prophet. But, now, I wonder whether 2006 is time for celebration of my failure. From voices usually well informed, we hear repeated stories that the…
