Photographer Bob Carlos Clarke has died aged 55 after being hit by a train on a level crossing in southwest London.
Police say they are not treating the death as suspicious, following a report by a witness at the scene.
The award-winning photographer worked in many areas of photography, including fashion, advertising and photojournalism. He has also captured many portraits of high-profile celebrities.
Carlos Clarke was one of the first photographers to use the Olympus E-System, which received its UK launch in his London studio.
Among those paying tribute was former Guardian picture editor Eamonn McCabe who described him as ?Mapplethorpe without the mystery?.
A spokeswoman for Olympus said: ?Bob was a great character and a true professional. Without doubt he was one of the most provocative and creative photographers of the twentieth century.?
Carlos Clarke left Ireland in 1964 for the West Sussex College of Art where he became interested in photography. He went on to the London College of Printing before taking a degree at the Royal College of Art in 1975.
Danny Chau, who prints Carlos Clarke?s digital images, said the photographer had been planning a ?major exhibition? involving Asia and UK-based photographers.
Steven Brierley, sales director of Ilford Photo said: ?He was a very charismatic person, a real live wire who bounced from one creative idea to another. He had phenomenal energy and was a lot of fun to be around.?
Carlos Clarke died on 25 March after being hit by a Waterloo-bound train at the White Hart Lane level crossing near Barnes.
An inquest into the death has been opened and adjourned to a date yet to be fixed.
