Shooting Nudibranchs

Published

on

In recent years we have witnessed a rise in the popularity of nudibranchs amongst the scuba diving community, both as a photographic subject and from a natural history point of view. Now that underwater photographers and non photographers alike are seeing these little creatures with a new understanding and renewed interest in their many fascinating forms and behaviours, we are also seeing a rise in tempting photo competitions with dedicated nudibranch categories. In fact very recently I had the privilege to see almost 900 nudibranch photos submitted from photographers in 33 countries to the nudibranch Photo Competition which I was involved in running. And perhaps the most telling sign of this rise in popularity is Alex Mustard’s cover shot of a nudibranch on a UK diving magazine back in January – not a diver, drysuit or bit of shiny tech diving kit anywhere to be seen; just a gorgeous Polycera quadrilineata.

Feeding into, and feeding from, this popularity are numerous macro specific  photographic trips and one or two nudibranch safaris being run around the world. A hugely popular trip based in Europe is the Gulen Dive Resort Nudibranch safari in Norway. This isn’t for the feint-hearted as water temperatures can be as low as 2 degrees C, but the clear waters and sheer numbers of slugs (both species and abundance) draws many scientists and underwater photographers to the annual event.

There is a great deal of cross-over between nudibranch photographers and marine scientists who share the same interest. The photographers gain insights into the behaviour, location and abundance of many species; and the scientists get access to many detailed images and greater number of in-water observations that would  normally not be possible.

Many photographers develop their own favourite style or technique for shooting in different situations; quite often this is led by the development of new kit, or simply what is considered a fashionable ‘look’ at the time. Taking images of nudibranchs is no different and their many shapes, sizes and forms make them suitable subjects for a variety of techniques.

The most basic approach is to see them as a traditional macro subject and apply  tried & tested rules of engagement: macro lens, high shutter speed, small aperture and strobes. Compact camera users need not feel left out, as many models have superb macro capabilities which can be further enhanced using additional close-up ‘wet’ lenses.

Moving beyond this method can open up a whole new creative world to the slug shooter. If you like velvety black backgrounds you might want to try using snoots on your strobes, using ‘inward-lighting’ techniques (where you aim your strobes back in towards the camera & use the very edge of the light cone to light the subject), and cutting your kit down to just a single handle and strobe to facilitate getting very close to your subject.

Going in the opposite direction and keeping some ambient light in your shots will often involve careful control of the strobe as TTL metering sometimes tends to overexpose in this situation so using your strobe in manual can yield much better results.

If you are shooting in temperate waters where ambient light levels are very much lower, keeping an adequate depth-of-field by using your aperture will necessitate using higher ISO settings & lower shutter speeds to let that light into your image. Playing to the strengths of your kit in these situations always pays dividends; if your image stabilization is better than your high ISO performance, then use slower shutter speeds, if not then ISO should be your tool of choice.

Taking a different view of nudibranchs is perhaps where you’ll start to see the greatest opportunities for amazing photos. Observation can be the key to getting interesting behaviour photos and as these critters can move surprisingly quickly, take some practice shots before you carefully approach the subject so you are ready for the action.

Almost every aspect of a nudibranch’s life can be used for behaviour photography; aggregations, mating, egg-lying, feeding, cresting a pebble or frond of weed and sometimes even swimming in midwater give plenty of chances if you know where & when to look.

Close-focus wide-angle is another technique which can be applied to the larger species of nudis. Again, compact camera users are not disadvantaged because many wideangle or fisheye wet lenses have very good close focusing abilities. The most problematic aspect of a CFWA nudibranch shot is getting the light to the subject; the ability to reduce the size of your camera rig and get your strobes as tight to your port as possible is the key. This approach can be used to include a diver in the shot, or perhaps more interestingly place the nudibranch in its habitat – often they feed and live in very colourful and interesting places which can be used to make beautiful images.

As is common practice amongst the majority of underwater photographers, a respect for nudibranchs and their habitat is paramount. This is not just for the benefit of the slugs themselves because if you adopt a sensible and conservation-minded attitude in the water then your images will benefit too.

Many species of nudibranch live on mucky/silty sites so poor finning technique or  buoyancy will disturb the sediment and ruin your photographic opportunities.

In every corner of the globe where slugs are found, using just one finger to steady yourself while keeping your body/fins away from the reef/wall/sea-bed should be your standard approach. Just because you can’t see a slug or its food or eggs doesn’t mean they’re not there!

If you shoot for competitions, nudibranchs are a surprisingly versatile subject in their own right and you don’t even need a dedicated category to benefit from their many forms. Lots of competitions have ‘abstract’, ‘behaviour’ and ‘portrait’ categories which all lend themselves to photos of nudis. Applying the techniques discussed previously you’ve also got opportunities in ‘traditional macro’, ‘super macro’ and ‘wide-angle’ categories too.

Sometimes competitions throw up oddly themed sections to test the entrants’ creative abilities. Themes like ‘reflections’, or ‘yellow’ and ‘camouflage’ can all be useful to the nudibranch photographer if you know your species and have the ability to go & find them!

If in-camera manipulation is permitted you can try your hand at a double (or more) exposure that places a close-up shot of a nudibranch onto a cleverly exposed sun-ball or diver silhouette. Tricky to pull off well; but stunning if done properly.

The increasing appeal of nudibranchs is perhaps, in part, down to the fact that there are still new species waiting to be discovered. Even in the most popular diving destinations in the world, every now and then something new pops up and gets the scientists, and photographers, all excited.

In completing the necessary dives for my recent iBook on nudibranchs of south west England, my buddy (and fellow author) Terry Griffiths and I stumbled upon a potential 4 new species whilst diving sites we had be visiting for many years.

It will take some time, and many more dives, to confirm; but the fact illustrates that there’s still so much more out there to be discovered.

Dan has been diving in the UK for over 25 years and has built up a vast knowledge of the marine life found in our waters. Taking underwater photos for the past 15 years has culminated in Dan twice winning the British Underwater Photography Championships.

Nauticam SMC-3

The SMC-3

Nauticam is proud to introduce the SMC-3, the latest evolution in our line of water contact optics! Designed as a renewed version of the acclaimed SMC-1, the SMC-3 boasts a lightweight build—now only one-third the weight of its predecessor—without compromising on optical performance.

Nauticam SMC-3

Tested with Nikon AF-S VR Micro-Nikkor 105mm f/2.8G IF-ED

Key Features

  • Ultra-Lightweight Design: Weighing in at just one-third of the SMC-1, the SMC-3 offers unparalleled portability for on-the-go use.
  • Superior Optical Performance: Enjoy the same exceptional clarity and precision you’ve come to expect from the SMC series.
  • Increased Working Distance: The redesigned lens allows for a greater working distance, meaning it’s easier to use and provides enhanced versatility.
  • Premium Materials: Crafted with advanced materials to enhance durability while minimizing weight.
  • Cost-Effective: Slightly more affordable than the discontinued SMC-1, the SMC-3 delivers exceptional value.

Uncompromised Optical Quality

The Super Macro Converter 3 is constructed from lenses that are precision crafted of specially formulated low dispersion optical grade glass, ground to the most demanding standards. These exceptional measures, enhanced by broadband anti-refective coatings effectively reduce common optical issues such as chromatic aberrations, coma, spherical aberration, and field deformation associated with underwater macro photography using traditional magnifying lenses. These optics are assembled in a rugged hard anodized aluminum housing, and nitrogen purged during assembly to eliminate fogging.

Stunning Magnification

When combined with a full frame camera and a 100mm or 105mm macro lens, the device converts the optical system to provide a maximum of 2.4X magnification factor. In other words, a subject area of 15.6mm X 10.4mm will fill the whole frame of a 36mm X 24mm sensor.

Improved Sharpness and Contrast

As the Super Macro Converter 3 is optimized explicitly for using together with a macro lens underwater, images captured exhibit exceptional sharpness compared with conventional magnification lenses. Thanks to the broadband multi-layer anti-reflection coating on each surface of the lenses, images also exhibit higher contrast.

Superb Light Transmission

All the lens elements installed inside the SMC are optically optimized to appropriate diameters so as to provide maximum light transmission. The SMC doesn’t suffer from vignette issues under even the most extreme conditions. The broad band multi-layer anti-reflection coating on all surfaces also greatly improves light transmission.

Optimized for Autofocus

By utilizing a specially developed algorithm in the optimization process, the SMC renders superior image quality over the full focusing range of the camera lens (which becomes ~50 to ~100 mm in front of the SMC). Also benefitting from the high brightness and contrast of the image, the autofocus system of the camera usually works acceptably well within this range.

Nauticam SMC-3

Ample Working Distance

Even at the maximum 2.3X magnification, there is still more than 50mm of working distance between the front element and the subject with 100/105mm macro lenses. This working distance is crucial when capturing behavior with skittish subjects.

Resolution

High resolution was a primary design goal of the SMC project. This has been achieved using computer aided optimization and high grade optical glasses with unique refractive and dispersion properties. Images taken with this new system exhibit very high resolution and quality. Results have exceeded expectations, and these images rival the quality of the macro lens in air.

Smooth Bokeh

The Converter retains the optical properties of the macro lens for the whole system underwater, resulting in a blurred (out of focus) background that has a pleasing smoothness and creamy look, without the normal purple and green fringing.

Avoiding Diffraction

Due to the overall superior optical performance of the SMC-3 it is possible to shoot larger apertures with excellent image quality. This avoids reaching the diffraction limit of high resolution sensors, and allows selective focus effects with narrow depth of field in super macro images.
