Subject: A Pink Whipray (Himantura fai) lies on a sandy bottom where it is getting a rapid clean by Bluestreak Cleaner Wrasse (Labroides dimidiatus). Although the Blacklip or Sunburst Butterflyfish (Chaetodon ) aren’t considered cleaners, they use the presented opportunity to get their piece of the pie.
Technique: To avoid spooking the subject with my camera lights, I turned them off and increased the ISO, resulting in quite a noisy image. I used an orange filter to filter out the blue. The noise was easily removed in post-processing by applying a noise reducing generator. Fine-tuning the colours and adding a bit of contrast resulted in a satisfying shot.
