“ Hello Matti, let me join in the discussion in a constructive tone at all. As you can read from my "signature" I am convinced that all or almost all photographers, including myself, are a little daffodils paronoici, and those who do fotonatura maybe even more. But considering that almost all are, and luckily, naturalists believe and practitioners. You start by saying that from zoos, circuses, etc.. I have the DASPO! (The last time I was there armed with shears to cut the nets) ... joke of course, but it is only to be understood that the naturalist has an understandable aversion to animals photographed in captivity. Myself I have a skepticism and not posterei ever, except that does not even photographer, pictures of animals in environments that someone called and checked that I think are areas of constriction. When I see some photos I will only observe with sadness and did not comment. Said cI also understand that not everyone has the good fortune to attend the Masai Mara and the Serengeti and I am also convinced of the freedom of criticism in the field of civil and polite discussion. Ultimately, you should accept criticism, even the beasts (there may be a naturalist convinced), but collect only those targeted to the technical aspect. I wish you a nice trip in African parks! In the meantime, I suggest you attend the parks in your city (Racconigi, Stupinigi, the PO) and practice there. And 'better a nice picture of a "banal" stork or a swan or a coot, but free rather than a picture of an animal in captivity, the picture might be technically valid, but the animal will always and clearly his state of compulsion! Best of luck! „
