Subject: Long-Snouted Spinner Dolphins (Stenella longirostris) come closer to shore during the early hours to rest, play and mate. In the afternoon they leave the tranquility of the shallows and head for deeper and open water where they start their nocturnal hunt on schooling fish and squid. Due to the tuna fisheries they are now globally endangered.
Technique: When making underwater videos it is always a bonus to add some out-of-the-water footage (drone images in this case). Filming the water surface brings an extra challenge; light reflection. These reflections are easily dealt with by using a polarizing filter. Light reflections are impossible to remove in post-production so prevention is key.
