How to Choose the Best Photo for a Custom Oil Portrait

Why Your Photo Is the Foundation of a Great Oil Portrait

Every custom oil portrait begins with a photograph. It is the single most important input in the entire process — more influential than canvas size, paint quality, or even the artist's skill level. A sharp, well-lit reference photo gives the artist everything they need to create a portrait with depth, emotion, and lifelike accuracy. A poor photo limits what's achievable, no matter how talented the painter.

The good news? You don't need a professional camera or a studio setup. A modern smartphone and an understanding of a few key principles are all it takes to capture a reference photo that will produce a stunning oil portrait.

The 7 Qualities of an Ideal Reference Photo

After painting thousands of custom portraits, our artists at PaintForU have identified the seven qualities that consistently produce the best results.

1. Sharp Focus — Especially on the Eyes

The eyes are the emotional centre of every portrait. They communicate personality, mood, and connection. If the eyes are blurry, the entire painting loses its impact.

How to get it right:

• Tap on the subject's face (specifically the eyes) on your phone screen to lock focus
• Hold the camera steady — brace your elbows against your body or lean against a wall
• For pets, wait for a moment of stillness and use burst mode to capture multiple frames
• Check the photo at full zoom before moving on — what looks sharp on a small screen may be soft when enlarged

A slightly blurry body or background is perfectly acceptable. But the eyes must be tack-sharp.

2. Natural, Soft Lighting

Lighting determines how your subject's features are rendered — the contours of the face, the warmth of skin tones, the depth of shadows. Natural, diffused light is the gold standard for portrait reference photos.

Best lighting conditions:

• Overcast days — clouds act as a giant softbox, producing even, flattering light
• Window light — position your subject facing a large window (not in direct sun)
• Golden hour — the hour after sunrise or before sunset produces warm, directional light
• Open shade — under a tree or awning on a sunny day

What to avoid:

• Direct flash — flattens features, creates harsh shadows, and produces red-eye
• Overhead midday sun — creates unflattering shadows under the eyes and nose
• Mixed lighting — combining warm indoor lamps with cool daylight creates colour casts
• Backlit subjects — where the light source is behind the subject, silhouetting the face

3. Sufficient Resolution

Higher resolution means more detail for the artist to work with. This translates directly into finer brushwork, more accurate features, and a more lifelike finished portrait.

Minimum requirements:

• Small canvas (8×10): 1 megapixel (1000×1000 pixels)
• Medium canvas (12×16): 2 megapixels
• Large canvas (18×24): 3+ megapixels
• XL canvas (24×36): 4+ megapixels

Most modern smartphones capture 12–48 megapixels, so resolution is rarely an issue — unless you're heavily cropping, using a screenshot, or downloading a compressed image from social media.

Pro tip: Always send the original photo file, not a screenshot or a version downloaded from Instagram or Facebook. Social media platforms heavily compress images, stripping away the detail our artists need.

4. Natural, Authentic Expression

The best portraits capture genuine emotion — not a forced smile held for three seconds while someone counts down. The most meaningful oil paintings come from photos that show the subject as they truly are.

How to capture authentic expression:

• For people: Engage them in conversation while photographing. Ask about something that makes them happy. Capture the laugh, the thoughtful pause, the natural grin.
• For children: Let them play and shoot candidly. The best child portraits come from unposed moments of curiosity, joy, or concentration.
• For pets: Use their favourite toy or treat to get their attention. Capture the alert ears, the curious head tilt, the relaxed smile.
• For couples: Ask them to look at each other, whisper something, or share a private joke. The connection between them will shine through in the painting.

5. Eye-Level Perspective

Camera angle dramatically affects how the subject appears. Shooting from above makes people look smaller and less powerful. Shooting from below can distort proportions and create unflattering angles.

The rule: Position the camera at the subject's eye level.

• For adults: Hold the camera at face height
• For children: Kneel or sit down to their level
• For pets: Get down on the floor — yes, really. Lie on your stomach if needed.
• For babies: Place the camera at mattress or blanket level

Eye-level shots create a sense of direct connection between the viewer and the subject. This is what makes a portrait feel like the person (or pet) is looking right at you.

6. Clean, Simple Composition

The subject should be the clear focus of the image. A busy background, other people partially in frame, or distracting objects compete for attention and make the artist's job harder.

Composition tips:

• Fill the frame with the subject — face and upper body for most portraits
• Avoid cropping too tightly (leave space around the head for the artist to compose)
• Move clutter out of the background before shooting
• Use portrait mode on your phone to blur the background naturally

Don't worry about the background too much — our artists can replace it with any setting you choose. But a simpler starting point means more of the artist's time goes into perfecting the subject rather than working around distractions.

7. No Heavy Filters or Edits

This is one of the most common mistakes we see. Beauty filters, Instagram presets, HDR effects, and AI enhancements all alter the photo in ways that compromise the portrait.

What filters change:

• Skin tones — smoothed, warmed, or cooled unnaturally
• Contrast — crushed shadows and blown highlights hide facial detail
• Sharpness — artificial sharpening creates halos and artifacts
• Colour balance — shifted hues make accurate colour mixing impossible
• Facial features — beauty modes slim faces, enlarge eyes, and smooth skin texture

Always submit the original, unedited photo. If the only version you have is filtered, let us know and our artists will do their best to compensate — but the result will always be more accurate from an unfiltered original.

Photo Scenarios: What Works and What Doesn't

Great Reference Photos

• ✅ Clear, sharp face with natural smile in soft window light
• ✅ Pet looking at camera with bright, alert eyes in outdoor shade
• ✅ Couple laughing together, faces close, natural daylight
• ✅ Child playing, candid moment, good ambient light
• ✅ Formal portrait with studio lighting (professional photos work excellently)

Photos That Need Extra Care

• ⚠️ Group photo where the subject's face is small — we can work with it, but detail is limited
• ⚠️ Photo from a distance — cropping reduces resolution significantly
• ⚠️ Old printed photo (scan at 300 DPI minimum)
• ⚠️ Screenshot from a video call — very low resolution

Photos to Avoid If Possible

• ❌ Heavy flash with red-eye and flat lighting
• ❌ Silhouetted or severely backlit faces
• ❌ Heavily filtered/beauty-mode images
• ❌ Extremely blurry or out-of-focus shots
• ❌ Thumbnail-sized images from social media

Special Situations

Memorial Portraits

When the perfect photo doesn't exist — especially for portraits of loved ones who have passed — send us everything you have. Multiple imperfect photos are often better than one. Our artists can composite elements from several images: the smile from one photo, the outfit from another, and a meaningful background from a third. Read our full memorial portrait guide for more advice.

Combining Multiple People or Pets

Want to paint family members who were never in the same photo together? We do this regularly. Submit individual photos of each subject, ideally taken in similar lighting conditions. Include notes about how you'd like them arranged in the final composition.

Old or Damaged Photographs

Faded, yellowed, or physically damaged prints can still produce beautiful oil portraits. Scan the photo at 300 DPI or higher. Our artists will interpret colour and detail based on what's visible, and you can specify preferences for skin tones, hair colour, and clothing if the original has lost detail.
