They construct a foam nest on a tree branch above a still water source. Eventually the foam liquefies when the eggs are ready to hatch.

Not all frogs survive to make the nest. The Akamata is the most common snake on the Okinawan Islands.  It feeds on venomous habu snakes, baby sea turtles, lizards and frogs.

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)

Here are some of my favorite wide-angle macro images photographed in Okinawa-Japan.

Crabs With Beach Trash Homes – Okinawa, Japan

Featured

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 nature 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.

Below are some of my favorite images photographed on a portable field studio board (MYN Technique). The crabs are safely placed on a white studio board, photographed and released back into the natural environment (MYN Technique).

It’s important to photograph the hermit crabs in their natural habitat.  I prefer to photograph them using a wide angle lens to achieve a unique perspective.

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.

Our trash is becoming a serous problem on our shorelines! Let’s keep our shorelines clean!

Have a great day!
