Landing the perfect underwater macro shot isn't easy: light behaves differently beneath the waves, and flitting fishes aren't always willing subjects. But with a bit of practice and a lot of patience, closeup photography can bring the hidden lives of the ocean's smaller inhabitants into focus. 

During a recent workshop in Lembeh, Indonesia, our friends at WetPixel set off to accomplish this feat – and the resulting images are beyond beautiful.

The workshop was taught by renowned photographer Alex Mustard, who led participants on a few dives each day during the event. "The pace was quite tough!" says the WetPixel team. "However, as the images below show, the results were outstanding. They are a visual feast!"

From colourful cuttlefish to well-camouflaged pygmy seahorses, the crew managed to capture some of the most vibrant marine life that Indonesia has to offer.

Smaller than a paperclip, pygmy seahorses are so well camouflaged that they weren't discovered by scientists until their coralline homes were brought into a lab in 1969. This pink and white morph is found exclusively on the coral Muricella plectra. Image: WetPixel Full Frame/used with permission
