I usually find this turtle crossing the road at night or early in the morning.

This was a large turtle with a previous injury more than likely caused by a vehicle. Look close to see the cracking in the shell.

The truth is I have seen more of these turtles dead than alive. Please watch your speed and pay close attention to crossing wildlife.

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.

Laowa 12mm f/2.8 Zero-D Lens for Canon EF

The Laowa D-Dreamer 12mm lens is a technical lens with great optics. The specialized lens is manual focus and manual aperture selection. I decided to see what it could do underwater.

The lens was used in combination with a Canon 70d DSLR, mounted in an Ikelite housing with an eight-inch dome port. For all the underwater shots, I preset the aperture to f11 before I locked it in the underwater housing. I tested it under ambient light, with the use of modeling lights and underwater strobes. I only had time to test it four times underwater due to bad weather and family obligations. It was challenging for sure. By the fourth dive, I started getting the hang of using this manual lens underwater.

1st issue – Reflection when shooting into the sunlight. (see the bottom right corner)

I made an anti-reflection lens ring cover to reduce reflection and eliminate the letters and numbers in my image.

2nd issue – Locking on focus. Many of my images were soft due to user error and malfunctions. The focus ring kept slipping off. I adapted with some orange nonstick stretch tape to prevent it from slipping again.

If you plan to use this lens underwater I would recommend a camera body that has focus peaking. I tested it without the function and had some difficulty underwater. Below are some of my favorite photographs using the Laowa D-Dreamer 12mm lens underwater. Okinawa, Japan

To be expected the Laowa 12mm f/2.8 Zero-D lens was a lot easier to use on land. Below are some of my documentation photographs of the marine debris washed ashore on local beaches.

I hope these photographs will inspire people to care more about nature and make difference in the environment
