How to Choose the Perfect Photo for Your Custom Oil Painting Portrait

You have just decided to commission a custom oil painting from a photo. Congratulations — you are about to own something most people never will: a one-of-a-kind, hand-painted artwork made just for you, that will outlast every smartphone screen, every cloud account, and every framed print on your wall.

But here is the honest truth most studios will not tell you: the single biggest factor in how beautiful your finished painting turns out is the photo you send us. A great photo unlocks a great painting. A blurry, dark, or tiny photo forces our artist to guess — and even the best artist in the world cannot paint what they cannot see.

This guide walks you through exactly what makes a great reference photo for a hand-painted oil portrait, with examples of what to send and what to avoid.

The 5 things that make a great reference photo

1. High resolution

The single most important factor. Aim for a photo that is at least 1500 pixels on the long edge. Modern smartphones (iPhone 11 and later, Samsung Galaxy S10 and later) capture more than enough resolution by default — just make sure you are sending the original, not a screenshot or a downloaded social media version.

Pro tip: If you are sending a photo via email or messaging, choose the "original size" or "actual size" option when prompted. Apps like iMessage, WhatsApp, and Gmail often compress photos by default, and a compressed photo loses 60–80% of its detail.

2. Good lighting on the subject

Soft, even lighting is your best friend. Natural daylight from a window, an overcast day outdoors, or the golden hour just before sunset all produce flattering light. Avoid:

Direct overhead sun — creates harsh shadows under eyes and chins
Backlit photos — the subject becomes a silhouette and details disappear
Camera flash up close — flattens features and causes red-eye in pets and people
Heavy mixed lighting — for example, half-shadow, half-bright sun on a face

If your only good photo of a beloved pet or family member has tricky lighting, send it anyway. Our artists can often work around imperfect light — but a well-lit photo always produces a better painting.

3. Sharp focus on the subject's face

For portraits — whether human, dog, cat, or horse — the eyes are the soul of the painting. Make sure they are in sharp focus, not blurred by motion or out-of-focus camera autofocus. A simple test: zoom in to the subject's eyes on your phone. Can you see the highlights and details clearly? If yes, the photo is sharp enough.

4. Natural expression

Your artist will paint exactly what is in the photo. If your dog is mid-yawn, the painting will be a mid-yawn dog. If your grandmother's eyes are half-closed, the painting will look the same. Choose a photo where the expression captures the personality you love — a happy smile, a soft serious look, an alert head tilt, a playful gaze.

5. The angle and framing you want in the painting

Whatever the photo shows is what the painting will show. If you want a head-and-shoulders portrait, send a photo cropped to head and shoulders. If you want a full-body painting, send a full-body photo. Side profiles, three-quarter views, and straight-on portraits all work beautifully — but the angle in the photo is the angle in the painting.

What to do if your only good photo is not perfect

This happens often, especially for pet memorial paintings or portraits of older family members. Maybe the photo is from years ago, slightly blurry, or low resolution. Send it anyway.

Our professional artists have decades of experience working with imperfect references. We can:

Combine details from multiple photos into one painting
Sharpen and enhance features when the photo lacks detail
Adjust lighting and color in the painting to flatter the subject
Use a reference of a similar breed or person to fill in details

Before the artist begins, our team will review your photo and let you know honestly whether it will produce a great painting or whether we recommend a different photo. We never start painting until you are confident in the reference.

What about photos of multiple pets or family members?

If you want one painting of multiple subjects — say, two dogs, a couple, or a family of four — you have two options:

Send a photo where everyone is already in the same shot together. This is always best because the lighting and proportions are consistent.
Send separate photos of each subject. Our artist can compose them together into one painting. When sending separate photos, try to match the lighting and angle if possible.

For multi-subject paintings, larger canvas sizes (20×24" and up) work best so each face has room to breathe.

The bottom line

A great photo is the foundation of a great painting. But please do not let perfection stop you — send us whatever you have, and we will tell you honestly whether it will work. Most of the time the answer is yes, and our artists will make magic with what you send.
