A zoo is the easiest place to stand two metres from a lion, and the hardest place to come home with a photograph of one. The animal is right there. So is the wire, the glass, the painted wall, the keeper’s door and the flat white light of one o’clock. Almost none of that is about camera settings, which is the good news. It is about where you put your feet and what you leave out of the frame.
What gives a zoo picture away is everything around the animal. A photo reads as wildlife when nothing in it was made by people, and it reads as a day out the moment one thing was. Straight lines are the usual giveaway, because nothing in a forest is straight and everything we build is. Your job for the afternoon is to get rid of them, roughly in this order: the barrier, the background, the edges of the frame, and last of all the light.
The fence: get closer than the camera can focus
A wire fence in front of an animal is not really an obstacle. It is a focus problem. Anything much closer than the thing you focused on comes out soft, and anything both very close and very soft spreads out until it is a faint haze over the picture rather than a bar across it.
Three things do this, and they all push the same way. Put the front of the lens as close to the wire as the zoo allows, touching it if you can. Open the aperture as wide as the lens goes, f/2.8 or f/4. Use a longer lens, because a long lens wide open has the thinnest sharp zone you can buy. Then focus on the animal instead of the fence, which usually means switching to a single focus point and putting it on the eye. Left alone, the camera will cheerfully grab the nearest thing it can see, and the nearest thing is the wire.
Shoot through a gap. Aiming through the middle of a diamond of mesh, rather than across a wire, gives the lens a clear view, and a hand-sized gap is plenty. What ruins it is sun landing on the wire. A lit fence is a bright object, and bright objects survive being blurred. If the wire is in sun and the animal is in shade, walk round and shoot from the other side.
Glass: you are fighting the reflection, not the pane
Glass is a different problem with an easier answer. The pane does not smudge your picture. It adds a second picture on top: everything bright behind you, laid over everything in front of you. So the question is never how to beat the glass. It is what the glass is showing you right now.
The fix that always works is contact. Press a rubber lens hood flat against the pane and no side light can reach the front of the lens, which kills the reflection completely and steadies the camera while it is at it. If you cannot do that, hold a dark coat, or your own body, between the light behind you and the lens. A polarising filter helps at an angle and does very little straight on, so treat it as a backup rather than the plan.
Drag the diagram and watch what the pane bounces back. The bit worth remembering: the reflection is not of you standing in front of the glass. It is of whatever happens to sit at the mirror angle, which is why moving a metre along the window is often the whole solution. And clean the glass first if you are allowed. Fingerprints at a wide aperture turn into a grey fog across the frame, and nobody can remove that afterwards.
The background gives you away, not the animal
Nobody looks at a photo of a tiger and thinks about the tiger’s enclosure. They think about the drainpipe behind its head. Backgrounds are where zoo photos are really lost, and they are the cheapest thing on this page to fix, because the fix is free and takes two seconds.
Move. One step sideways swings the far background across the frame much further than it moves the animal, so a sign, a handrail or a bright patch of sky can be walked right out of the picture while your subject stays put. Crouching does the same thing up and down. Get low and the background becomes the far bank instead of the concrete path, and you end up at the animal’s eye level, which is worth having anyway.
What you want behind an animal is tone, not detail: leaves in shade, dark water, a wall in shadow, anything with no edges of its own. A background that is simply darker than the animal reads as depth, even when it is a painted breeze block six metres away. If none of that is available, shoot from below so the sky is behind it, and set the exposure for the animal.
Fill the frame, then fill it more
The most useful habit is to include less. A tight shot of a face, a pair of eyes, the texture of a hide or the pattern of a feather says nothing about where it was taken, and it is usually the better photograph anyway. Peacock feathers was taken in a zoo. Nothing in the frame says so, because the frame holds nothing but feathers: no wire, no rail, no painted wall, no sky. That is the whole trick, and it is a crop rather than a skill.
In practice that means a long lens, 200mm or more, or standing close to the barrier with something shorter. It also means cropping afterwards without feeling bad about it. A 24 megapixel file has plenty of room in it, and half of one still prints beautifully at the sizes most people hang. Turn the camera upright too: most animals are taller than they are wide once you are close enough for it to matter.
Time is the gear nobody brings
A zoo rewards patience more than anywhere else, because captive animals are the most predictable subjects in photography. They walk the same route, sleep in the same corner, come to the same rail at the same hour, and the keepers feed them on a timetable you can read at the gate.
So pick one enclosure and stay there. Watch a full lap without lifting the camera. Find the one spot on the route where the animal comes near the glass with a clean background behind it. Focus there, and wait for it to come round again. Ten quiet minutes at one window beats an hour of walking, and it is the difference between a snapshot of an animal and a photograph of one.
The best hours are also the emptiest. Come at opening time or in the last hour, when the light is low and warm instead of white and overhead, the animals are awake and moving, and nobody is at your elbow. The sleeping giant in the catalogue is a late-afternoon picture, and the light is doing at least half the work.
Settings, briefly
Very little of this is about settings, but you do not want them fighting you either. Use aperture priority at the widest aperture your lens has, a single focus point on the eye, continuous focus if the animal is moving, and auto ISO with a minimum shutter speed set. That last one is the setting most people never find, and it does the thinking for you: tell the camera never to go below 1/500 and it will raise the ISO rather than hand you a soft picture.
Grain is not the enemy people think it is. A slightly grainy sharp photo is a photo. A clean blurry one is nothing. Shoot raw if your camera offers it, because zoo light is usually a mix of daylight and lamps, and a raw file lets you fix a colour cast that a JPEG locks in.
And the manners
No flash, ever, through glass or otherwise. It bounces straight back off the pane and wrecks the picture, and more importantly it is unkind to a night animal that cannot walk away from it. Do not tap the glass, do not whistle or call to make an animal turn its head, do not lean over a barrier. Those rules are there for the animals, not for you, and a photograph that needed one broken is not worth having.
Where to start, by enclosure
Starting points, not rules. Every row assumes the widest aperture your lens actually has, and assumes you have already taken a step sideways to see what is behind the animal.
| Enclosure | Aperture | Shutter | The move that matters |
|---|---|---|---|
| Big cat behind glass | f/2.8 to f/4 | 1/250 | Hood on the pane |
| Anything behind wire | f/2.8, wide as it goes | 1/500 | Lens at the wire |
| Walk-through aviary | f/4 | 1/1000 | Shoot upward, sky behind |
| Peacock or ground bird | f/4 to f/5.6 | 1/500 | Kneel to its eye level |
| Primate house, indoors | f/2.8 | 1/250 | Let ISO go high |
| Nocturnal house | f/2.8, wide as it goes | 1/60, braced | Camera against the rail |
| Aquarium tank | f/2.8 to f/4 | 1/125 | Square to the glass, no flash |
| Reptile in a vivarium | f/5.6 to f/8 | 1/125 | Focus the eye, not the scales |
| Open outdoor enclosure | f/4 to f/5.6 | 1/1000 | Wait for the near rail |
| Penguin or seal pool | f/4 | 1/1000 to 1/2000 | Pre-focus where they surface |
| Sleeping animal, late light | f/2.8 to f/4 | 1/250 | Expose for the lit side |
Handheld, keep the shutter faster than one over the focal length whatever the table says, and remember that stabilisation steadies the camera and not the animal.
The short version
- A fence disappears when the lens is against it and the aperture is wide. Focus past it, on the eye.
- Glass gives back whatever sits at the mirror angle. Press the hood to the pane, or move until that angle is something dark.
- Two steps sideways rebuild the background. The animal barely moves; the drainpipe leaves.
- Fill the frame until nothing man-made is left in it, then crop tighter still.
- Pick one enclosure, learn the route, and wait for it to come back.
- First hour or last hour. Never a flash.
