The Art of Wide-Angle Macro Photography by Shawn Miller

Posted on December 20, 2014 by Admin11

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”

Ryukyu black-breasted leaf turtle, Yanbaru forest

Posted on November 10, 2014 by Admin11

The Ryukyu black-breasted leaf turtle (Geoemyda japonica) is an endangered species found in Northern Okinawa. This turtle is decreasing in numbers due to poaching, deforestation and roadkill. The turtle is highly valued in the pet trade market and needs to be protected. It has been designated as a National Natural Monument of Japan and is currently on the IUCN red species list as endangered.

Scientific name: Geoemyda japonica (Fan, 1931)
Distribution: Okinawajima
Habitat: Leaf littered wetland forests
Diet: Worms, snails, insects, crustaceans, and fruit
Average Size: 140mm- 160mm

Crabs With Beach Trash Homes – Okinawa, Japan

Posted on October 19, 2014 by Admin11

Crabs with beach trash homes is a series I am currently working on. I photograph Blueberry hermit crabs (Coenobita purpureus) that have begun to use beach trash as their home. The crabs are photographed in their natural environment and also on white for the Meet Your Neighbours global biodiversity project. The images are used for environmental awareness and educational purposes.

Blueberry hermit crabs are commonly found on local beaches in Okinawa. Most crabs are blue but occasionally have color variations of purple, pink, orange and or gray. They prefer to have a seashell as a protective home but when no shell is available they adapt.

Before plastic caps filled our shorelines, hermit crabs adapted using tree nuts if no shells were available.

It’s becoming more common to find crabs with beach trash homes. I have friends combing local beaches in search of more crabs for my series. While these are cute images, our trash is becoming a serious problem to the ocean and the animals that call the shoreline home. I often find hermit crabs using a variety of plastic caps from twist top pet bottles, laundry detergent containers, small propane tanks, sports water bottles and beauty supplies.

Possible reason why Blueberry crabs adapt with beach trash

Limited number of available shells causing them to make due with the best homes they can find. This is a good example of adaptive behavior.

Hermit crabs are very social animals and often fight over shells. Having a protective lightweight shell that covers the abdomen (soft parts of the animal) is crucial for survival.

Hermit crabs are scavengers and take advantage of any food washed ashore. They mainly feed on dead fish, barnacles, other crabs, algae, insects, plants, fruit and various seeds. The screw pine (Pandanus odifer) is one of their favorite foods. I imagine long ago these vital plants lined our shorelines in abundance. Numbers are decreasing due to deforestation.

Eventually the fruit drops to the ground and the sweet smell attracts the hermit crabs

The hermit crabs feed on the the fresh keys and help with seed dispersal. They both benefit in this relationship. The Pandanus tree provides shelter, shade, food for the hermit crabs.

Eventually the keys dry, turn brown and litter the local beaches. The dispersed keys provide a perfect environment for hermit crabs to blend in with.

Hermit crabs prefer to be in a shell that protects the entire body from predators. Sometimes they have to temporarily adapt with a much smaller shell. The retracted hermit crab tightens up to protect itself. Ball up, play dead and blend into the environment, minimizing the risk of being preyed upon.

Could this be a form of masquerading or just coincidence ? It resembles (mimics) the shape of the screw pine seed to possibly avoid detection from potential predators.

I also photograph the hermit crabs using a dedicated macro lens. I mainly use the Canon 60 mm or 100 mm macro lens to concentrate on the subject. These crabs are fairly small and it’s important to have a lens that will focus close and deliver high quality sharpness.

School project ” Crabs with beach trash homes ” My family and I collected trash on a local beach in Onna village. This is just a small portion of our beach trash findings. The kids did a great job creating a project with impact.

Otis Brunner found this hermit crab flattened on a beachside parking lot. As you can see the plastic doesn’t provide much protection.

Behind the scenes photograph ” Crabs with beach trash homes ” I have documented over sixty crabs with beach trash homes. If you would like to see more images check out my Flickr account.

Slow Down! – Let’s Protect The Okinawa Rail

Posted on August 26, 2014 by Admin11

The Okinawa rail is a flightless bird found in northern Okinawa. It is a protected species and declared a living natural treasure. It is currently listed by the International Union for Conservation of Nature (IUCN) as an endangered species. In 2012 populations of this endemic bird were estimated at 1500 by the Environment Ministry. As of October 2016 populations have declined to 480 mature individuals according to IUCN assessment.

Scientific name: Hypotaenidia okinawae

Common Name: Okinawa Rail

Distribution: Northern Okinawa

Habitat: Forests

Diet: Small insects, worms, snails and fruit.

Average Size: 31cm

Threats: Habitat loss and the threat of Jungle crows and mongoose.

The rail is often found feeding on the side of the road. It feeds on worms, snails, and insects.

When defending its territory, the rail will become aggressive and flare its wings.

If you are lucky you can catch the Okinawa rail feeding on the fruit of the cherry tree.

They roost high above the ground to avoid predators like the habu snake.

Okinawa rail roosting ( Hypotaenidia okinawae)

In 2014 I stumbled upon Scientists handling an adult Okinawa rail in the wild.

Awareness signs are posted along the main roads in northern Okinawa for their protection. I think they should also include speed bumps in the designated crossing areas for the rails.

The speed limit is only 40km/h so watch your speed for the protection of the wildlife. The rails are often seen feeding on the side of the road.

I have observed these birds crossing the road on many occasions. They have no problems crossing when people are driving the speed limit. Speeding decreases your reaction time, slow down and pay attention to all crossing wildlife.

What to do if you find an injured rail.

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.

Facing extinction – Ishikawa’s Frog (Odorrana ishikawae)

Posted on June 13, 2014 by Admin11

Ishikawa’s frog (Odorrana ishikawae) is the most beautiful frog found in Japan. It is only found in northern Okinawa and currently on the endangered species list. It is one of the many endemic species facing extinction due to habitat loss. Ishikawa’s frog is a designated living national treasure of Okinawa.

Scientific name: Odorrana ishikawae
Distribution: Northern Okinawa-Japan
Habitat: Forest streams
Diet: Insects, worms, and millipedes
Average Size: 90mm -120mm

This is my favorite frog on Okinawa. I have only seen about a dozen in the last three years.

shikawa's Frog (Odorrana ishikawae) Yanbaru forest ,Okinawa

They live around mountain streams in the Yanbaru forest. They hide in cracks and crevices in the rocks making it hard to photograph them at times.

They are also masters of camouflage. The unique pattern helps them blend into the moss and leaves on the riverside.

The Ishikawa’s frog was featured in Amphibian Love – an artbook for the frogs. Artist Leah Jay created this book to show the beauty and fascinating variety of amphibians, and bring attention the the Amphibian Extinction Crisis.

If you are lucky you might find a blue Ishikawa’s frog. The blue morph is absolutely beautiful.
