Prompts for Pet Photography

The line between a convincing pet photograph and a stuffed-toy render runs through two things: how the fur is lit and where the camera is standing. Almost every generated dog or cat that looks wrong is lit flat from the front and shot from a standing human’s eye level, which is exactly how nobody photographs animals well.

Fur Needs a Light Behind It

Fur is thousands of semi-transparent strands, and it only looks like fur when light passes through the edges. Put a light source behind and slightly to one side of the animal and ask for a rim of backlight along the back, ears and tail — that halo of lit strands is the single most effective thing you can write into a pet prompt. Front light alone renders the coat as a solid painted shape.

Coat type deserves a specific word rather than a colour. Short and slick over visible muscle, dense double coat that stands away from the body, long silky fur that parts and falls, wiry terrier coat that sticks out in irregular tufts, or curly poodle-type pile that reads as texture rather than strands. Whiskers are worth naming separately, since they need a dark background behind them to show up at all.

Get the Camera Down to the Animal

Shoot at the animal’s eye level. Say it in the prompt — “camera at floor level, lens at the dog’s eye height” — because the default is a downward angle that shortens the muzzle and makes the animal look small and submissive. Down at their level you get eye contact, a clean background of whatever is behind them rather than the floor, and a natural sense of the animal as the subject.

Focal length behaves as it does with people, with one caveat: short lenses close up will balloon the nose. A 50mm to 135mm from a metre or two away keeps the head in proportion. Ask for focus on the near eye specifically, with a shallow depth of field if you want the background gone — catchlights in the eyes are what makes the animal look alive, so ask for those too and name the light shape that causes them, like a window to camera left.

Behaviour Is More Useful Than Pose

“Sitting dog” is a stiff instruction. Describe a moment instead: ears pricked and head tilted at a sound off-frame, mid-shake with water spraying off the coat, a cat crouched low with the tail tip flicking, a puppy caught mid-run with all four feet off the ground and ears lifted. Action needs a fast shutter stated outright, or you get smear. Add the eyeline — looking straight into the lens, or off toward something at the edge of the frame — since an unspecified gaze usually comes back vacant.

Test it this way: generate the same animal twice, once with backlight and once with flat front light, everything else unchanged. Zoom into the ear edge and the shoulder. If you cannot see individual strands catching the light, no amount of “highly detailed fur” will fix it — the problem is the light direction, not the description.
