Over the last two decades, many efforts have been devoted to the search for brown dwarfs, and various ways of finding them have been developed. Deep photometric surveys in nearby open clusters is one approach that has provided a large amount of candidates. These clusters offer a number of advantages (a single known distance, metallicity and age)
