             How to take good underwater shots




                                                           When  taking  photos  underwater, using  ei-
                                                           ther  digital  or  conventional  cameras,  fol-
                                                           lowing basic rules is necessary. Before div-
                                                           ing,  prepare  yourself  and  the  camera.  To
                                                           achieve the most beautiful shots, you must
                                                           control  your  breathing  and  buoyancy. The
                                                           key to achieve this is having concentration.
                                                           Second,  compose  the  photo  you  want  to

                                                           take in your mind, then find the best spot
                                                           and angle for the shot. Sudden movements
                                                           may scare animals away so approach your
             subject with care. The virtue of patience is of advantage. Be patient while waiting for
             a good pose from the subject. Then, take multiple shots of a single subject. This will
             help you look for your best shot. Taking a close up shot is easy with digital cameras,
             but it is best to take the actual close up shot than using zoom to get closer to the
             subject. To shoot macros (with or without macro lens), the camera’s aperture should
             be set to its highest value for a maximum contrast. If having problems focusing on the
             subject, switch to manual focus and set it to the smallest available focal distance. A
             good impression of the reef and surroundings is delivered by wide-angle shots. Set
             the shutter speed to 1/125 or less, in order to freeze actions of most fishes. The best
             time to take good underwater shots is during the middle of the day where there is
             strong sunshine and clear water.
