I am a photographer whose body of work spans two decades and covers almost five continents. Spain, Rwanda, China, Vietnam, Argentina, Brazil or Mexico are some of the countries where I have been. I have contributed to many publications, conferences and exhibitions as a professor of Fine Arts at the University of Barcelona.  I would like to think that no area of photography has escaped my attention even though my principal interest can be Documentary Photography.  Black and white and color images of various types including pinhole, panoramic, medium and large formats can be found in my portfolios.
