Reference Photo for a Pet Portrait Tattoo — the practical guide

The photo decides. A clear photo gives a clear tattoo. A blurry or badly lit photo can’t be “saved” even by the best tattoo artist — information that isn’t in the photo can’t go on the skin. I’m Jon, pet portrait specialist at Sinkply Zürich, and in this guide I walk you through exactly what a reference photo needs to look like so the tattoo really ends up looking like your animal. And — more importantly — how to shoot it yourself with your phone, without studio equipment.

This is the practical part we’d otherwise walk through over WhatsApp. Once you’ve internalised this brief, we both save a round of back-and-forth — and we start the design in half the time.

The five things that actually matter

Before we go into detail, the short version. A good reference photo has:

1. Natural daylight — soft, indirect, not direct sun
2. At the animal’s eye level — the camera is where they look
3. Sharp focus on the eyes — everything else can be softer
4. High resolution — at least 1200 pixels on the longest side
5. Calm, natural expression — not the “treat is coming” face, not a startled one

Everything else is refinement. If those five are right, we have enough to work with.

Light — the single most important factor

Light makes or breaks a photo. Most phone snapshots fail here, not on the camera model. The rules:

Good light

• Daylight from a large window with the animal side-on to the window
• Outdoors in shade on a bright day (for example, a covered terrace)
• Early morning or late afternoon, when the sun isn’t slamming straight down
• Evenly diffused light without hard shadows

Bad light

• Direct on-camera flash — flattens the fur, kills the eyes, throws a shadow behind the head
• Direct midday sun — hard shadows under the chin and in the eye sockets
• Backlight (window behind the animal) — the face goes dark, only a silhouette remains
• Warm indoor lighting (incandescent bulbs) — turns the fur orange and distorts the real colour

Rule of thumb: if you can look at the animal comfortably without squinting, the light is usable.

Angle — get down to eye level

The most common photo problem I see: people shoot from above. They stand next to the dog, hold the phone down and click. The result: a distorted head, small eyes, a dominant skull and an expression that isn’t “the animal”.

The fix is uncomfortable but effective: get down. Sit, lie down, crouch. The camera needs to be where the animal sees the world — at their eye level. That’s the only way you get:

• Correct head proportions
• Eyes at their actual size
• A face that looks like “him”, not like a creature looking up at you

Exception: if your animal is very large (horse, big dog), shoot at their eye level while standing. The principle holds: never from above.

Sharp eyes — everything else can be soft

Modern phones have a portrait mode or a tap-to-focus. Use it. Tap the screen on your animal’s eye before you press the shutter. The phone then focuses exactly on the eye and lets the rest go slightly soft.

Why that matters: in the tattoo, the eye carries the expression. If the eye is out of focus in the photo, I can’t reconstruct the pupil, the light reflex and the fine lines of the iris — the result looks lifeless. If the eye is sharp, I have the information I need to draw the animal alive. Fur, ears, shoulders I can pull from other photos. The eyes need a sharp photo.

Tip: if your animal won’t hold still, use burst mode (hold down the shutter — the phone takes 10 to 20 shots per second). In a burst of 50 you’ll almost always find one with sharp eyes.

Resolution and file format

The photo needs enough pixels for me to go deep on the face. Targets:

• At least 1200 pixels on the longest side — roughly the standard resolution of a modern phone as long as you haven’t digitally zoomed
• JPG or HEIC straight from the phone — not screenshots from Instagram, not photos from WhatsApp voice notes, not images that have already been forwarded three times
• Send me the original, not a screenshot. WhatsApp has a “send as document” option — use it, the messenger compresses less aggressively that way

If you have videos but no sharp stills, send the video. I extract a sharp frame from it. That often works surprisingly well.

Expression — the detail that makes or breaks it

A photo can be technically perfect and still be the wrong photo. Because the expression isn’t right. Two common traps:

The treat face. You grab the snack, the animal pricks their ears, the eyes go big, the body tenses. You take the photo — and what’s on it is an animal waiting for food. Not your animal in everyday life. That won’t be “him” in ten years.

The startled face. You call, the animal whips their head around, you hit the shutter. The face is half turned, the ears in a random position, the expression alien.

What you want: the calm moment. The animal lying, sitting, standing — and looking in your direction, or just past it, without any external trigger. That’s their real expression. The look you know from sitting on the sofa together in the evening. The look you want in the tattoo.

Tip: say their name softly while shooting. Not in the treat voice. In the normal everyday voice. The ears prick moderately, the expression stays natural.

Three to five photos, not one

Even if one photo is perfect, I want several. Reason: the best portrait is often built from a composition. Body and shoulders from one image, head angle from another, gaze from a third. If you send me three to five perspectives, I can combine the best of each.

Concretely ideal:

• One photo head straight on, directly into the camera
• One photo head slightly angled (three-quarter profile) so I understand the head shape
• One photo full body for proportions and posture
• One photo specific details if there are notable features (collar, scar, one white paw)
• One photo in a typical moment — favourite spot, the head tilt, etc.

Fewer is okay, more is better. I’d rather scan through ten photos for the two that carry the strongest information.

What won’t work

To be explicit, here are the photos I can’t work from:

• Blurry shots (motion blur)
• Very dark images (“it was late, the light was bad”)
• Heavy Instagram filter (lost contrast, shifted colour)
• Black-and-white conversions when the original was colour — I need the fur information
• Screenshots from social media (compression destroys detail)
• Photos from far away (animal takes up less than 30% of the frame)
• Photos with a hat, bandana, costume or flower crown that partially covers the face
• Selfies with you and the animal (you usually take up half the frame)

If you’re unsure whether your photos are enough — send them anyway. I’ll tell you honestly whether we can work with them or whether you should grab two or three extra shots. The briefing is free, and it’s better that we sort this before the first draft.

If the animal is no longer alive

I often have clients who only have photos that are ten years old, printed on paper, photographed off Polaroids, or digitised. That’s not a dealbreaker. We’ve tattooed pet portraits from very old, very imperfect photos — as long as the eyes and the expression are recognisable, we can work.

Things you can do in that case:

• Photograph the printed photo in daylight, as straight-on as possible, without shadows, on your phone
• If you have digital originals (old JPGs from an old phone), send those — even if they’re small
• Videos from back then are gold, if you can find any

That’s often the starting point for memorial work. More on that in our article on pet memorial tattoos in Zürich.

How to send the photos

Send them via WhatsApp to +41 77 212 07 67. In the WhatsApp app there are two ways:

• As a photo: the default, gets compressed. Usually fine, saves data
• As a document: option under “send file → photos & videos”. Not compressed, keeps full resolution. Use this if your photos are high-res and you want to make sure I get the full detail

Add the animal’s name, approximate age, desired body placement and rough size to the message. Then I have everything I need to get back to you within 48 hours with an estimate.

Next step

Take 20 minutes today or tomorrow. Go to a window with your animal, or outdoors into shade. Sit on the floor. Take three to five photos following the rules above. Send them to me. That’s the whole first step.
