How to Keep Underwater Photography Ethical: Approach, Distance, and Animal Behaviour

How to Keep Underwater Photography Ethical: Approach, Distance, and Animal Behaviour

Ethical underwater photography comes down to one principle: the animal's behaviour is your guide, not a fixed distance rule. Every species is different, every individual is different, and a manta ray that's had 300 encounters with divers behaves differently from one that hasn't. That said, there are frameworks — developed by marine biologists, dive operators, and conservation organisations — that give you a starting point before you get in the water. The general consensus: approach slowly and passively, stop when you're at a comfortable distance, and let the animal decide what happens next. If it moves toward you, you got lucky. If it alters course to avoid you, stop immediately and give it space. Never pursue. A 1m minimum distance is a common guideline for large rays and marine mammals, but distance alone isn't the point — watching for behavioural signals is. A 3m encounter where the animal is visibly stressed is worse than a 1m one where it's calm and undisturbed.

TL;DR: Passive approach + read behaviour = ethical photography. Distance guidelines (1–3m for rays, 5m for whale sharks) are minimums, not targets. If the animal changes direction to avoid you, you're too close. Wide angle lens discipline helps — you need to earn closeness.

The Difference Between Following and Chasing

This is the most misunderstood distinction in underwater photography. Following means staying in proximity to a moving animal while it continues its natural behaviour — it hasn't changed speed, direction, or demeanour. Chasing means closing distance when the animal is moving away from you. The difference matters because following a calm, undisturbed eagle ray for 30 seconds while it grazes is fundamentally different from pursuing a manta that's altered course twice to avoid you.

In practice, following is sometimes unavoidable — animals move, currents drift you, and you're finning to maintain buoyancy control anyway. The test is: are you matching the animal's path, or forcing it to alter its path? Watch specifically for tail-flick acceleration, sudden depth changes, or directional changes toward shelter. These are stress signals, full stop. One minute of following a genuinely calm eagle ray at 1m is probably fine; 20 seconds chasing a spooked manta is not.

Distance guidelines from established conservation bodies give you starting floors:

• Manta rays: 3m minimum (PADI Manta Network standard)
• Eagle rays: 1–2m is widely accepted in recreational contexts
• Whale sharks: 3m lateral, 4m from tail (IUCN guideline)
• Sea turtles: Don't approach while resting or nesting; 2m minimum while swimming

The 'Get Close and Closer' Advice — What Photographers Actually Mean

This advice exists in the context of photographic technique, not wildlife ethics, and gets misapplied constantly. What it means: the most common error in underwater photography is shooting from too far away, producing tiny subjects against busy water. Getting closer — optically and physically — produces better images with more compressed backgrounds and stronger subject separation. Wide-angle photography specifically rewards proximity because the lens has distortion characteristics that only resolve properly at short distances.

But the instruction assumes you've already read the animal and it's comfortable. You earn closeness — you don't take it. The photographers who can genuinely get within arm's reach of a manta ray and shoot are the ones who've spent years learning to move slowly underwater, control their bubbles, and read marine life body language. They don't close distance quickly. They hover, wait, and let the animal approach. The result looks effortless but involves enormous patience.

Red Flags in Your Own Behaviour to Watch For

• You're finning to close distance, not maintain position. If you're actively swimming toward the animal, that's pursuit.
• You lose track of time. As described in the Palau encounter — the hyped state of getting a good shot compresses time perception. Set a mental limit before you get in the water: 60 seconds max per approach, then back off regardless.
• You're watching the viewfinder, not the animal. The screen or viewfinder disconnects you from real-time behaviour signals. Experienced underwater photographers spend as much time looking around the camera as through it.
• You're using a strobe flash repeatedly on the same animal. Limited flash use is generally fine; sustained strobing at close range on a single animal causes measurable stress.
• You rationalize 'it didn't react so it was fine.' Animals suppress stress responses in the presence of predators — stillness isn't always comfort.

Practical Workflow for Ethical Approach

1. Get neutrally buoyant before you approach. Rushing to close distance while fighting your BC adds erratic movement that spooks animals.
2. Approach at 45° from the front, not directly head-on. Less threatening — mirrors how divers are trained to approach large animals in underwater naturalist courses.
3. Slow your breathing. Bubble noise and rate are the biggest disturbance factors. Long, slow breaths reduce both.
4. Set a time limit before you start. 60 seconds max, then you assess and back off regardless of how the shot is going.
5. Watch body language, not just distance. You should be spending half your attention on the animal's behaviour, not the camera frame.
6. If it reacts, give 5m of space immediately. Let it settle, then assess whether to approach again — or not.

The Bottom Line

The guilt you feel after an encounter that felt borderline is a useful calibration tool. Most experienced underwater photographers describe a similar learning curve — hyped state, lost time, retrospective unease. That self-monitoring is what separates photographers who eventually get the shots ethically from those who keep rationalising.

If you want to formalise this, PADI's Underwater Naturalist specialty covers marine behaviour and ethical approach in a structured way — it's a one-day course that most dive schools offer. Worth considering after a trip like Palau where you're clearly thinking seriously about this.
