This is Part 2 of 10 Part Underwater Natural Light Photography Series.

When shooting underwater using natural light, the euphotic zone is your playground. This is the uppermost layer of water that sunlight penetrates, and it’s where natural light photography truly comes to life. Understanding how light interacts with water in this zone is essential for creating stunning underwater images.

What is the Euphotic Zone?

The euphotic zone is the part of any body of water that receives bright and clear sunlight. Even in turbid, murky water, there’s always a euphotic zone—though it might only extend a few inches deep. In the tropics, where water clarity is exceptional, the euphotic zone can extend well beyond 260 feet—far past recreational diving depths.

This zone is where sunlight, or ambient light, allows photographers to capture natural, vibrant underwater scenes. For those relying on natural light, the euphotic zone is your best friend.

Here are two examples of wildlife thriving in very different Euphotic Zones: the pink dolphin of the Amazon River and the lemon shark of the Bahamas. Each represents the unique beauty and diversity of life in their distinct aquatic worlds. The pink dolphin thrives in the dim, low-light conditions of the Amazon River, navigating its murky waters with remarkable adaptations that allow it to flourish in this unique environment. In stark contrast, the lemon shark thrives in the clear, sunlit waters of the Bahamas, where high visibility and abundant light create the perfect conditions for this sleek predator to navigate and hunt.

How Light Behaves Underwater

Light behaves very differently underwater than it does on land. Water is about 800 times denser than air, which causes light to scatter and absorb quickly as it penetrates. The deeper you go, the more light—and color—you lose.

Here’s how color disappears at different depths:

  • Red vanishes around 15 feet.

  • Orange fades by 30 feet.

  • Yellow disappears by 60 feet.

  • Green is absorbed around 100 feet, leaving only blues.

This means that the deeper you dive, the more muted and monochromatic your images will appear. Natural light photographers need to work within these limitations to create vibrant and well-exposed photos.

Tips for Working in the Euphotic Zone

  1. Stay Shallow:
    The closer you are to the surface, the more light and color you’ll have. For the best results shoot wildlife above 30 feet where reds and oranges are still visible.

  2. Time Your Dives:
    Early morning and late afternoon offer soft, diffused light that can add mood and dimension to your photos. Midday dives provide the most light penetration, which is great for capturing vibrant colors at deeper depths.

  3. Understand Water Clarity:
    Clear tropical waters extend the depth of the euphotic zone, while murky or nutrient-rich waters will reduce it significantly. Adjust your expectations and camera settings accordingly.

  4. Position the Sun Behind You:
    Just like on land, keeping the sun at your back ensures your subject is well-lit and shadows are minimized. Unless you are going for an artsy image and then you want your subject to be backlit by the sun.

The Challenges of the Euphotic Zone

Natural light photography in the euphotic zone is not without its difficulties. Clouds, tides, and weather can all affect light penetration. Additionally, the further you descend, the harder it becomes to maintain vibrant colors without proper camera settings and techniques like custom white balance (which I’ll cover in a future post).

Why the Euphotic Zone is Worth It

Despite the challenges, the euphotic zone offers unparalleled opportunities for natural light photographers. The sunlight filtering through water creates breathtaking effects, like god rays that cut through the blue, or the shimmering light patterns on the ocean floor. These natural phenomena can add depth and drama to your images, creating compositions that feel both authentic and otherworldly.

Why Choose Natural Light for Underwater Photography?

When it comes to underwater photography, strobes are often the go-to choice for professionals. They bring out vibrant colors and allow for incredible detail in any lighting condition. However, there’s another side to underwater photography that’s often overlooked but equally exciting… Natural Light Photography.

This approach leverages ambient light from the sun to create images with a more organic and authentic feel. It’s less intrusive to wildlife, offers greater freedom of movement, and provides a unique challenge that pushes your skills as a photographer.

Let’s dive into why natural light photography is worth exploring.

One of the biggest advantages of natural light photography is the freedom it gives you underwater. Without strobes and bulky strobe arms attached to your camera rig, you’re far more streamlined. This makes swimming easier, especially when free diving or dealing with strong currents.

More importantly, it allows you to move fluidly and follow wildlife with minimal disruption.

Animals are often spooked by flashing lights, but with natural light, you can get closer and stay longer, building trust and capturing more intimate moments.

Natural light photography is less intrusive, which can be a game-changer when photographing sensitive marine animals like sharks, whales, and dolphins. Without the startling pop of a strobe, they are more likely to stay calm and tolerate your presence.

Some of my favorite moments underwater have been with animals mere inches from my dome port, calmly going about their lives. It’s these moments that make natural light photography so rewarding—it’s not just about capturing a shot but trying to experience a genuine connection with the wildlife.

Of course, natural light photography comes with its challenges. The underwater environment absorbs light and color at different depths:

  • Red disappears around 15 feet.

  • Orange fades by 30 feet.

  • Yellow is gone by 60 feet.

  • Greens fade by 100 feet, leaving mostly blues.

This means your ability to capture vibrant images depends heavily on factors like depth, water clarity, and time of day. Cloudy skies or low light conditions can make it even more difficult, requiring careful adjustments to your camera settings.

Despite the challenges, natural light photography is incredibly rewarding.

It forces you to think creatively, adapt to your environment, and work within the constraints of the available light. But, when you nail the exposure, composition, and timing, the results are nothing short of magical.

To me, natural light images have a raw, authentic feel that strobes can’t replicate. They reflect the beauty of the underwater world as it truly is—dynamic, ever-changing, and awe-inspiring.

Photo of the Day: Cenote Diving for a Morelet’s Crocodile in Tulum

1/250, f/9, ISO 1600

Today’s photo takes me back to an unforgettable cenote dive in Tulum, Mexico. I had the opportunity to go searching for a Morelet’s crocodile with a local guide and friend Tamara, who knew just the right spot where one of these elusive creatures is often sighted.

What made this dive unique was being able to use scuba gear. Typically, my crocodile encounters happen while snorkeling, but here I had the rare chance to explore the lagoon with a tank on my back. Cenote diving is an adventure in itself, with stunning swim-throughs, intricate rock formations, and the magical effect of light piercing through the water to create ethereal god rays.

We swam through the cenote for a while without any sign of the crocodile.

Just as we were beginning to think it might not show, we entered one of the cenote’s caves. Deep inside, in a small breathing hole, we finally spotted the croc. It seemed to be hiding there to escape the crowds of snorkeling tourists.

1/250, f/9, ISO 1600

Our bubbles inadvertently disturbed its rest, (sorry buddy), and it swam out of the cave and back into the lagoon. I followed it for a while, capturing different angles as it swam off. This Morelet’s crocodile was very calm, clearly habituated to humans. It allowed me to get close and take some fun shots.

I love crocodiles, their prehistoric features make them such fascinating and photogenic subjects.

1/200, f/9, ISO 1600

Photographing Morelet’s crocodiles in a cenote presents a unique challenge—low light, murky water, and the need for precision in settings. Unlike shooting in open ocean or bright sunlit environments, cenotes create a dim, shadowy atmosphere where every camera setting becomes a delicate balancing act.

One of the biggest obstacles was managing light without sacrificing clarity. The thick overhead canopy and deep water columns absorbed natural light, forcing me to make critical adjustments on the fly.

To compensate for the darkness, I had to lower my shutter speed while still keeping it fast enough to freeze any sudden movement. Bumping up my ISO was unavoidable, knowing that noise would creep into the image, but it was a necessary trade-off to maintain exposure.

I kept my f-stop at 9 to ensure the entire crocodile remained in focus. A wider aperture would have helped let in more light, but losing depth of field wasn’t an option. I wanted the full length of the animal sharp.

This meant dealing with increased noise in the shadows, a challenge that would later require noise reduction editing in post. But in that moment, it was about getting the shot, adjusting in real-time, and working with the limited natural light.

Photographing a predator like this in such conditions forces you to trust your instincts, adapt your settings, and embrace the imperfections that come with shooting in extreme environments.

1/200, f/9, ISO 1600

I spent about half an hour photographing the croc, enjoying the animal and the scenery before leaving it alone to continue its day.

It’s been a while since that adventure, but I’m due to return for another opportunity to capture this amazing animal in its natural habitat. Cenote diving is a unique experience, and sharing space with an animal like this only adds to the magic.

Through the Lens: Capturing Wildlife Moments That Tell a Story

Wildlife photography is so much more than just taking a picture. It’s about telling a story—one that evokes emotion, inspires awe, and sometimes even drives conservation efforts.

Through your lens, you’re not just capturing an image; you’re sharing a piece of the natural world that many people will never experience firsthand.

Great wildlife photography begins long before you press the shutter.

It starts with understanding animal behavior, researching the environment, and having the right gear for the job. Having good guides that know when and where to find your subject can make all the difference in the world.

Timing your trips around migrations or mating seasons can provide incredible opportunities to witness unique behaviors.

Equally important is your equipment. While you don’t need the fanciest gear, having the right lens and a camera that performs well in low light can help make your shots better.

HOT TIP. Always carry extra batteries and memory cards—you never know when the perfect moment will happen. If nothing else I shared doesn’t resonate, remember this tip… I learned this one the hard way.

Capturing dramatic compositions is key to creating images that stand out.

Use natural light to your advantage, whether it’s the golden glow of sunrise or the soft hues of sunset. Pay attention to your background and how it might complement your subject.

For fast-moving animals, mastering your camera’s focus settings is essential. Practice panning with moving subjects to achieve sharp focus on the animal while keeping a sense of motion in the image. And don’t be afraid to experiment—sometimes, the unexpected angles produce the most compelling results.

Wildlife photography comes with a responsibility to respect the animals and their environment.

Always keep a safe distance and avoid actions that could stress or disrupt the animal’s natural behavior. Remember, a great shot is never worth compromising the well-being of the wildlife you’re photographing.

While portraits of animals are beautiful, my personal favorite images are behavior shots.

There’s something magical about capturing an animal in action—whether it’s a whale breaching, a bird feeding its chicks, or a predator stalking prey.

Behavior images tell a story and bring the animal’s world to life in a way that static portraits simply cannot.

One of my most memorable shots was of a bobcat catching a bird while jumping through the air. The image was not perfect, however the long hours we put into trying to capture this wild moment is why this image will forever be one of my favorites.

Wildlife photography is a journey of patience, skill, passion, and a lot of luck!

Each image you capture is a window into the natural world. It is your chance to inspire, educate, and protect our beloved wildlife.

So grab your camera, step into the wild, and start telling stories.

Happy Thanksgiving (Or Just a Happy Family Day!)

I wanted to take a moment to reach out to all of you and wish you a Happy Thanksgiving, wherever you may be in the world. I know that not everyone celebrates this holiday—many countries don’t have a Thanksgiving tradition, and even here in the United States, there are ongoing discussions about its historical significance and the complexities tied to its origins.

I completely understand and respect those perspectives.

For me, however, Thanksgiving represents something simpler and more universal: an opportunity to gather with loved ones. It’s a day to pause, share time with family and friends, and appreciate the connections we have in our lives.

It also gives me a chance to share some of my favorite wild turkey images! I know not everyone appreciates these birds the way I do, but I think they are amazingly cool.

Their bold feathers, quirky personalities, and place in our ecosystems make them so much more than a holiday symbol.

So, whether or not you celebrate Thanksgiving, I want to take this moment to wish you a beautiful day filled with love, gratitude, and togetherness.

Wherever you are and whatever you’re doing, I hope your day is full of joy, connection, and peace.

Thank you for being part of this journey with us—it means more than you know.

Happy Thanksgiving, or simply, Happy Family Day!

A Fresh Start: Returning to My YouTube Channel

I started my YouTube channel back in 2011, inspired by a simple yet powerful idea: to share this incredible world without fences.

I wanted to bring people closer to the wild, to showcase the beauty and magic of this world that I love, and tell stories that matter.

But somewhere along the way, I got away from it all.

The truth is, I just wasn’t consistent with it. Recording video, editing footage, writing, crafting stories, and editing images—it’s a lot to take on, especially when you’re doing it all yourself.

It became overwhelming, and my focus shifted elsewhere.

Yet, despite stepping back—the love for sharing these wild places and incredible moments—never left me.

Now, I’m ready to return to the channel, to reconnect with what made me start this journey in the first place. Telling fun stories about the wildlife we encounter.

Of course my videos are not about perfection—it’s about sharing. Sharing raw, unfiltered moments, the challenges, the triumphs, and the beauty of the world I’m so lucky to explore.

I’ve realized that even if it’s not always polished, it’s worth it to share these stories. Because for every tiger sighting, every ibex photo, every encounter with a polar bear, there’s something deeper—a connection to nature that I hope inspires others to explore, protect, and cherish the wild.

I’m excited to get back into the rhythm of creating, even if it’s not always easy. Sharing these moments with you is what makes it worthwhile.

If you haven’t already, please subscribe to my channel, hit the notification bell, and join me on this journey.

Your support means everything. It helps grow this community of wildlife and adventure enthusiasts, and it fuels my motivation to keep going, even on the tough days.

A Heartfelt Thank You

For those who’ve been here since the beginning, like my buddy Steve Crawford, who is always encouraging me to share more stories… thank you! and to everyone who has been a part of this journey, thank you for sticking with me.

And for anyone just joining—welcome.

This is a new chapter, and I can’t wait to share it with all of you.

Let’s explore this world without fences, one story at a time.

The Double-Edged Sword of Ecotourism... Are We Loving Wildlife to Death?

Over the past decade, social media has transformed the way we connect with wildlife.

Stunning photos and videos of humpback whales breaching, polar bears roaming the tundra, or tigers stalking through the forest inspire millions to explore these wild places.

This surge in interest has fueled a massive growth in ecotourism, bringing much-needed attention and funding to local communities and conservation efforts.

But as more people flock to wildlife hotspots, it raises an important question:

Can we love an animal to death?

There’s no denying the power of witnessing wildlife up close.

These experiences foster deep connections and inspire a sense of responsibility for protecting our planet’s most vulnerable species.

Ecotourism provides vital economic support for local communities, often funding anti-poaching initiatives, habitat restoration, and education programs.

In my opinion, ecotourism is the key to the survival of many species.

The sad reality is that governments often don’t care about wildlife unless there’s money involved. They collect revenue either from ecotourism operators or from industries like fishing or hunting—and they don’t care which one it is… as long as the money flows their way.

This means that when wildlife has economic value tied to tourism, it’s more likely to be protected.

Ecotourism not only funds conservation efforts but also creates incentives for governments and communities to prioritize wildlife over exploitation.

Yet, there’s a darker side.

Increased human presence can disrupt natural behaviors. Animals may become stressed, altering their feeding, migration, or mating patterns. Some even become habituated to humans, which can put them at risk of harm or conflict.

The truth is, most animals don’t want us there.

Whether it’s a whale avoid boats, a fox fleeing at the sight of humans, or a bird scared off its nest, these are clear signs that our presence isn’t always welcome.

And I’m the first to admit, I’ve been guilty of this. I’ve wanted to see an animal and capture their beauty through a lens, even when they’ve shown signs of wanting to be left alone.

What I’ve learned over time, however, is that the true magic of wildlife encounters happens when an animal chooses to be in our presence… or tolerates it.

Through patience and respect, these moments are far more rewarding and meaningful. Watching an orca glide alongside our boat without fear or seeing a bear go about its life undisturbed—that’s when you truly feel a connection to the wild.

Despite the challenges, I firmly believe ecotourism is the only way to save wildlife.

It gives animals an economic value tied to their survival, creating incentives for protection rather than exploitation.

With respect and care, we can still visit our favorite wild places and create positive experiences for both people and wildlife.

As travelers, we hold the power to ensure that our adventures leave a positive impact:

  • Choose responsible operators who prioritize animal welfare and conservation.

  • Be respectful with wildlife, avoiding behaviors that may stress or scare them.

  • Use social media thoughtfully, avoid tagging/sharing fragile locations to prevent overcrowding.

By treading lightly and embracing responsible tourism, we can preserve the species we love while fostering deep connections that inspire conservation.

Ecotourism has the potential to be a powerful force for good… but only if it’s done right.

With patience, respect, and a focus on responsible travel, we can continue to explore the wild places we love while ensuring wildlife thrives for generations to come.

Thank you for reading.
