I photograph native cultures in Africa and Latin Aimerca (photos of traditional, tribal, rural, village life: daily activities; indigenous people). I am not forcing action, but instead letting impromptu situatios happen, getting a feeling as close as possible of life in villages or of interaction with the environment, trying not to impose my presence in the pictures. I also enjoy taking pictures of nature with, as far as possible, an emphasis on the relatinonship between the elements of the picture, taking an ecological approach: tropical biomes and ecology: photographs of rainforest and deforestation, savanna, desert, aquatic, mountain vegetation: life forms, foliage flowers) in tropical countries (Latin America, Africa, some Asia). When economic aspects of Brazil cross my way of course I photoraph them. As my main markets for stock photography are textbooks and travel publications, I am careful to correctly identify photographs with scientific name whenever relevant and possible, consulting a specialist if necessary. I will do additional research if requested. Links to related scientific articles in blog, if available and verified for legitimacy. Besides the main galleries of tropical cultures and tropical nature, I present smaller galleries of Europe and USA, of Asia and of automobile racing and rally.
