In my opinion a picture comes from a desire, it develops into an idea, converging in the subsequent active commitment in realizing it, with will, deployment of resources, time, knowledge, money and, in case of mountain photography, a lot of physical/mental effort.
This undertaking is on the spot. Therefore, it is essential a great knowledge of the places we want to capture. What they potentially can offer and when... with all possible approximations, because we work in direct contact with the unpredictable forces of nature.
The study of the exposure to the cardinal points is essential, as well as the study of the night sky on special maps for stars shooting.
We also need mountaineering-survival equipment suited to the places where we want to venture.
Post-production must be never invasive, in full respect to the supreme art of nature and to the enormous efforts made on the spot. Rather a valuable support to compensate the intrinsic limitations of our cameras.
