Nudibranch Photography – Mustard´s Masterclass

Master nudibranch pictures with Alex Mustard.

The Allure of the ‘Little Things’ Underwater

The decorations are up and presents are piling up below the tree, as I write on this chilly December morning. And for sure members of the family, the main focus may be very a lot on the smaller parcels. Because because the skilled know, the very best issues in life usually come within the smallest packages. The identical is true underwater, as a result of the longer we dive the extra our focus shifts and we study in regards to the wealthy rewards from diving slowly, wanting shut, and appreciating the little issues in life—the basic place to begin for wonderful nudibranch pictures.

Perhaps the most-prized tiny treasures are nudibranchs – vibrant, shell-less sea slugs. Despite some being smaller than the tip of your thumb, their gaudy colouration and kaleidoscopic patterns make them irresistible to underwater photographers. And whether or not you’re exploring coral reefs within the tropics or shipwrecks in British waters, you’ve a superb probability of recognizing these fascinating critters, in case you take the time to search for them.

Nudibranchs enchantment to photographers not simply due to their stunning colors, but in addition due to their fascinating biology. Nudis are hermaphrodites with a specialist mating behaviour and egg laying, harness a variety of dramatic defence mechanisms and promote them via hanging color, and show a outstanding variety of meals selections.

Essential Gear for Nudibranch Photography

Gear issues with sluggers for the easy purpose that they’re small and normally tucked down on the seabed. The place to begin is an effective macro lens, in calm, clear waters an extended focal size lens is best, however in decrease visibility a shorter focal size works greatest. While nudis are available in a variety of sizes, many of the greatest pictures require a bit bit extra magnification than a straight lens will give, particularly once we wish to fill the body with a head on pose. You don’t want a super-powered underwater dioptre for this, and this the place lower-powered, however high-quality supplementary lenses shine. Two I’d advocate testing are the Nauticam MFO-1 and the Kraken +6 lenses.

The various strategy is to realize that further magnification contained in the housing, both by including a skinny, autofocus appropriate extension tube to your lens, or utilizing a high-quality, non-underwater, supplementary close-up lens, just like the venerable Nikon 5T. Both of those choices are low-cost to purchase, however they do require a port extension, which frustratingly brings the overall worth near these the costly underwater lenses.

Nudis are normally connected to the underside and sometimes tucked down, not in the very best place for a photograph. So the very best strategy is a single, snooted strobe, to have the ability to highlight the slug and go away the environment at midnight. The outcomes are extremely efficient and permit the viewer an unobstructive view. I might simply warning that some photographers grow to be so targeted on the peerlessly posed portrait that they miss the larger story of the place the nudibranch resides and what it’s doing.

While nudibranchs are typically gradual transferring, once we wind up the magnification and shoot them with a razor skinny depth of discipline, they really transfer via our slim aircraft of focus annoyingly quick! It is essential to focus exactly on the rhinophores, that are the distinctive, antler-like chemo-sensory organs on their heads. I prefer to us monitoring autofocus on most topics, however with nudibranchs I are inclined to favour a spot focus that doesn’t try to comply with the topic, to make sure I get the main focus nailed.

The Nudi-Hunter’s Guide

Before we get to the capturing, the primary problem in nudibranch pictures is discovering them. And there’s undoubtedly a knack. Nudibranchs should not distributed evenly via the oceans; there are particular hotspots and particular seasons the place you’ll see way over your justifiable share.

In the tropics, the Philippines – significantly round Anilao – is a famend vacation spot, although many different locations come shut. In colder waters, nudibranchs could be much more quite a few, although biodiversity is decrease.

In the UK, for instance, it’s not unusual to drop in through the spring and discover the kelp lined in tons of of slugs, usually all from a single species. Nudibranchs are carnivores and feast on non-moving invertebrate life, so one of the simplest ways to seek out them is to search for their prey. Non-moving invertebrates typically thrive in areas of water motion, which they depend on to convey their meals. Therefore, our greatest probability of discovering slugs is in areas of present, significantly on pinnacles, wrecks, and rubble. Often, the very best giveaway is their giant, brightly colored egg ribbons, as they normally lay them near the place they’re dwelling.

The greatest strategy to study to seek out nudibranchs is to dive with devoted ‘nudi-hunters’. Around the world, nudispotting occasions happen, from liveaboard journeys in Indonesia to the favored Nudibranch Safari in Gulen, Norway. The nudi-lover sub-culture is a surprisingly vivacious department of diving, all the time eager to incorporate new members and educate them within the ‘ways of the slug’.

Composition and Perspective

The most-dramatic angle to shoot nudibranch portraits is from lifeless forward, framing the slug because it comes in direction of the lens. The goal is to have the rhinophores sharp within the foreground, framed towards the colorful slug behind. A vertically framed image is one of the simplest ways to fill the body with this composition, though being extra awkward, this orientation is taken much less. We ought to goal to get out digital camera proper all the way down to ‘eye’ degree, which provides the strongest reference to the topic and throws the background additional away. Both components enhance the influence of our image. If the slugger is on the transfer then watch and anticipate the second it crawls up and over one thing for that decisive second.

As a rule of thumb, the front-on angle works greatest with ‘sausage-shaped’ Dorid nudibranchs, whereas the aspect angle fits Aeolid nudibranchs – those with ‘lots of sausages on their backs’. Other angles additionally work effectively. If the nudibranch’s sample is totally on its again, shoot barely down on the topic. When the nudibranch is on a very photogenic background, attempt a totally top-down angle.

Capturing Behavior

Behaviour permits us to take our pictures up a notch and luckily nudibranchs are normally as much as one thing, when you study to recognise it. We recurrently see them paired up, proper aspect to proper aspect, mating, or going spherical in circles, laying their attribute spiralled egg ribbons. Sometimes, you’ll even discover different animals hitching a experience, akin to stunning emperor shrimp.

Photographing nudibranchs is each addictive and rewarding. Their variety, magnificence, and interesting behaviours supply infinite alternatives. So dive gradual, look shut, and let the ocean’s reward you with the very best presents.
