The Carl Zeiss Award, which has been running since 1991, is awarded for the photograph or set of photographs judged to have been the most instructive in the BBRC's assessment of rarities during the previous year. Once a final shortlist had been agreed, voting members of BBRC selected this year's winner and runners-up: each member simply ranked all the contenders in the list, and the one with the most points was the winner. A very strong shortlist this year reflects the still-increasing value of photographic documentation to the record-assessment process. As usual, the list included a mixture of images that were instructive in terms of the identification of difficult or poorly known species and subspecies together with those that simply provided categorical proof in support of a record that otherwise might not have been accepted.
