Best Photo Subjects for Paint by Numbers – Animals, Flowers & Landscapes

Not all photos convert equally well into paint by numbers canvases. The subject, lighting, and composition of your photo directly affect how satisfying the numbered canvas is to paint — and how good the result looks when finished.

Here's a breakdown of the most popular subject categories, what makes each work well, and how to choose the best photo in each category.

Why Subject Choice Matters

When a photo is converted to a paint by numbers canvas, the algorithm reduces colors and segments the image into numbered regions. Subjects with clear shapes, distinct color areas, and good contrast between elements produce clean, defined sections that are easy to identify and paint.

Subjects with muddy colors, heavily blurred backgrounds, or complex detail produce tiny, fragmented sections that are frustrating to paint.

The goal is a canvas where sections are clearly defined, large enough to paint without a magnifying glass, and visually recognizable as the subject you chose.

Animals

Why animals work so well: Animals have natural color zones — fur patterns, distinct body regions, clear background separation — that translate beautifully into numbered sections. The subject is immediately recognizable even at moderate simplification, and the emotional connection to a beloved pet makes the painting process more personally meaningful.

Best animal photos:

• Pets — your own dog or cat photographed in good natural light. Clear, close-up shots where the animal fills most of the frame.
• Wildlife — birds, foxes, deer. Works best with subjects that have distinctive markings (a toucan, a red fox, a panda) rather than uniformly colored animals.
• Close-up portraits — a single animal's face photographed from the front or at a slight angle gives the most detail.

What to avoid:

• Multiple animals in one frame (sections get fragmented between subjects)
• Animals photographed in low light (fur detail disappears)
• Very small animals where the body doesn't fill enough of the frame

Settings for animal canvases: 20–26 colors, simplification level 2–3. Animals need more colors than landscapes to capture fur texture and marking detail.

Flowers

Why flowers work so well: Flowers have large, naturally distinct color regions — petals, center, leaves, stem — that segment beautifully. The color variety in floral subjects is visually rich without being chaotic. And floral canvases are among the most rewarding to paint because the sections fill in quickly and the emerging image is immediately gratifying.

Best flower photos:

• Single bloom, close up — a single large flower filling the frame. Peony, sunflower, dahlia, rose, lily.
• Tight crop on petal detail — a macro-style shot that shows the color gradient within a single flower.
• Simple bouquet — 3–5 flowers arranged against a plain background. More complex than a single bloom but still very manageable.

What to avoid:

• Wildflower meadows or complex garden scenes (too many small shapes)
• Flowers photographed against similarly-colored backgrounds (petals and background merge in conversion)
• Very dark or heavily shadowed floral subjects

Settings for flower canvases: 18–24 colors, simplification level 2–3. Flowers can handle slightly less simplification because the sections are naturally larger.

Landscapes

Why landscapes work so well: Landscapes often have the largest sections of any subject type — sweeping sky areas, large ground sections, distinct horizon lines. They're excellent for beginners because the sections are manageable and the color palette is naturally limited (sky, ground, water, vegetation).

Best landscape photos:

• Dramatic skies — clouds, sunset, sunrise. The color variation in a good sky creates beautiful gradient sections.
• Minimalist compositions — wide open landscapes with distinct horizontal zones (sky, mountain, field, water).
• Single focal point — a lighthouse, a lone tree, a distant mountain. Clear subject against open background.
• Seasonal scenes — autumn forests, snowy fields, spring meadows. Strong color identity makes conversion clean.

What to avoid:

• Dense forest or jungle scenes (too many similar greens, too many small sections)
• Overcast, grey-sky landscapes (low color variation makes flat, uninteresting canvases)
• Nighttime scenes (insufficient color information for good conversion)

Settings for landscape canvases: 14–20 colors, simplification level 3–4. Landscapes need fewer colors and can handle higher simplification because the subject communicates well even in simplified form.

Portraits

Why portraits are popular but tricky: People want to paint photos of people they love — family members, partners, children. The emotional connection is strong. But portraits are technically the most challenging subject for paint by numbers conversion.

The challenge: Human faces require enough color nuance to look recognizable. Too few colors and the face looks flat. Too high simplification and the facial features lose their detail. Getting the balance right requires more experimentation than other subjects.

Best portrait photos:

• Good front-on lighting — soft, even natural light from a window. Avoid harsh direct sunlight or flash.
• Clear, close-up framing — the face should fill at least half the frame.
• Plain or blurred background — the subject should be distinctly separated from the background.
• Expression that involves clear features — a slight smile shows lip detail; a neutral expression works well for the eyes.

Settings for portrait canvases: 24–32 colors, simplification level 1–2. Portraits need maximum color range and minimum simplification to preserve facial recognizability.

Comparing Subject Difficulty

Using the Preview to Choose

The single best tool for subject selection is the live preview at TryPaintByNumbers.com.

How to use it:

1. Upload your photo
2. Try different color counts and simplification levels
3. Look at the preview — is the subject clearly recognizable? Are sections a manageable size?
4. If it looks good digitally, it will look good as a physical canvas too

If one photo doesn't convert well, try a different crop, a different shot of the same subject, or a different photo entirely. The preview is instant and free, so there's no cost to experimenting.

Most people find the right settings within 3–4 tries. The result is worth the experimentation — a canvas you'll enjoy painting and be proud to display.
