Last year I took a guided tour of Costa Rica, touching on five ecological zones in two weeks. With regard to photographs, guided tours offer some advantages. Relieved of the responsibility of deciding where to go, what to do, when to do it and what to eat, you can devote your mind fully to looking at things. The negative side is that you have little control over the position of your body in space: you don't want to give the guide anxieties by wandering off. Therefore, what's over there will forever remain over there. The working mode is to be on alert for images that may disappear in a second, taking pictures out the window of the bus if necessary. (As a footnote, the animals in the pictures appear in their natural environment.)
