True Fluorescence – Underwater photography by Shawn Miller

” Fluorescence is the absorption of electromagnetic radiation (light) at one wavelength and its re-emission at another, longer wavelength ” Dr Charles Mazel. I attached a link to his website at the bottom of the page for more info.

In order to photograph fluorescence you will need a excitation source (blue light), barrier filter and a camera.

Patterns, textures and colors ! Underwater Macro Photography by Shawn Miller

Okinawa offers some of the best Scuba-Diving in the world. I really enjoy the Art of Underwater Macro Photography.  Macro subjects can always be found, it just takes some imagination and good framing to create beautiful underwater abstracts.  Pattern’s, textures and vibrant colors generally stand out in underwater photography.

Equipment used 

  • Camera: Canon 70d with Canon 100mm&60mm
  • Housing: Ikelite underwater housing
  • Stobes: Ikelite DS160 & DS 200
  • Modeling lights: Light&Motion Gobe 800, Sola 3800 and Sola 1200
  • Specialized lights: Light&Motion Sola Nightsea

All images were taken in the beautiful waters of the Ryukyu Islands. Underwater Photography by Shawn Miller.

Ryukyu Long tailed Giant Rat – Ryukyu Islands

The Ryukyu Long-Tailed Giant Rat (Diplothrix legata) is an endangered species found on Amami, Tokuno and Okinawa Island. This rare species is currently listed as endangered on the IUCN red list of threatened species.  It’s biggest threats are deforestation, feral cats, dogs and the introduced mongoose. I often see it crossing the road during the night in the Yanbaru forest. Please pay attention to crossing wildlife and drive at a safe speed.

People often ask me what is the purpose of conservation photography? Having the ability to affect some form of positive change in the environment and make a global difference with the photographs. Hopefully, the images will inspire people to care more about nature and make a positive difference in the environment.

Nudibranchs – Colorful sea slugs of Okinawa

Nudibranchs are shell-less gastropods. They are some of the most bizarre-looking underwater animals found in our oceans. They can be challenging to find due to their small size and confusing patterns. Nudibranchs are slow-moving, delicate and lack a protective shell. Some are extremely distasteful and bright colors warn predators that they are toxic. Some even have the ability to ingest stinging cells and use them as a form of protection.

The best way to find sea slugs:    Move slow!  Search around sponges, hydroids, sea squirts, anemones, soft coral, rocks and reef ledges.

Train the eye:  They can be challenging to find, I recommend tagging along with experienced divers that already have an eye for finding them.

Below are some of my favorite images of sea slugs. Photography by Shawn M Miller.

Okinawan Sword-tailed newt – Endangered species by Shawn Miller

The Okinawan Sword-tailed newt (Cynops ensicauda popei) is an endangered species found on the main islands of Okinawa an Amami. It is currently listed as endangered on the IUCN red list of threatened species. This amphibian is decreasing in numbers due to deforestation and road kill.

  • Scientific name: Cynops ensicauda popei
  • Distribution: Okinawa and Anami Islands
  • Habitat: Forests, wetlands and freshwater streams
  • Diet: Amphibian eggs, tadpoles, snails, worms and insects
  • Average size: 100-180mm
Sword tailed newt with stripes

They all have bright orange bellies, which serve as a warning sign to predators that they are poisonous. When threatened they produce a transparent skin toxin.

  •  Poisonous animals are toxic if you eat them or ingest their secretions.  Irritations may occur after handling these newts if you have open wounds. Avoid rubbing your eyes or placing your hands in your mouth.

The government has designed specialized wildlife steps for animals that get trapped in roadside drainage ditches. These steps allow the newts to crawl out safely.

The Art of Underwater Motion by Shawn Miller

As an underwater photographer, there will be a time when you feel all your photographs look similar and you might lose interest for a while. Creating motion in still photographs will definitely give you a new challenge and purpose. The goal is to try to show some type of motion in a still photograph. The photographs emphasize the energy, power and or speed of the subject moving. Dramatic motion images will provide depth and variety to your portfolio.

Try panning or dragging the shutter underwater 

  • Move the camera in sync with the moving subject while the shutter stays open. A slow shutter speed will be necessary to achieve this.
  • Once you understand this technique try adding flash at the end of the exposure to freeze the motion of the subject (Rear curtain sync).
  • Get creative and add a spin the camera

  • Distribution:  Northern Okinawa-Japan
  • Habitat:  Forest streams 
  • Diet:  Insects, worms, snails and small reptiles
  • Average Size:  100mm -125mm

Capturing fluorescence – Fluorescence enhancement photography by Shawn Miller

Featured

All photographers experience a time when their work becomes redundant and lose vision. The Light & Motion Sola Nightsea has opened up a new style of photography for me. Recently I have been blending the Light&Motion Nightsea blue light with ambient light underwater and getting beautiful vibrant results.

Some of my Fluorescence enhancement coral images were featured in The Blue Planet 11 publication. It’s always nice to see years of hard work finally pay off.

The Art of Wide-Angle Macro Photography by Shawn Miller

Wide-angle macro photography is popular with wildlife photographers. The technique allows the photographer to document the animal in its natural habitat and show the full scene it lives in. The photographs have great impact and deliver a bug eye perspective using a wide angle lens. I generally use off-camera flash with a custom soft box to make these photographs. Lately, I have been testing a variety of on-camera flashes to achieve a different perspective. One of the biggest challenges is lighting the subject evenly with soft diffused lighting.

The most popular lenses used for wide angle macro photography ( WAM )  

  • Tokina fisheye 10-17mm f3.5-4.5
  • Nikon fisheye 10.5mm f2.8
  • Sigma fisheye 15mm f2.8 E
  • Venus Laowa 15mm f4 –    (Manual focus only)

The Tokina 10-17mm Fisheye is my favorite lens in my bag and has been my go-to lens for the project “Crabs with Beach Trash Homes”
