Ideogram 4.5 prompt guide

Start with the subject, then add context

The most common weak prompt is a bare noun: “cat”, “mountain”, “logo”. A model can't know what you actually want from a single word. Strong prompts open with a specific, described subject, then layer on where it is, how it looks, and how it's shot.

1. Weak: “a cat”
2. Better: “a fluffy orange cat sitting on a windowsill”
3. Strong: “a fluffy orange cat sitting on a windowsill, soft afternoon light, shallow depth of field, photographic”

Every detail you add constrains the result. Two or three specific details beat five vague ones — the model will follow a clear instruction more reliably than a crowded description.

Describe the style and treatment

The style preset on this site covers the broad look — photographic, anime, illustration, watercolor, 3D render, painting, sketch. Inside your prompt you can push further with treatment words: “film grain”, “studio lighting”, “flat vector illustration”, “hand-drawn ink”, “isometric”. Keep the treatment words consistent; mixing “photorealistic” with “cartoon” in one sentence splits the result.

Add lighting and camera language

Lighting changes the mood more than almost any other keyword, and it's cheap to add. Common ones that work well: “golden hour”, “soft morning light”, “dramatic rim light”, “neon reflections”, “overcast and moody”. Camera words — “wide angle”, “close-up”, “eye level”, “shot from above”, “shallow depth of field” — control composition. Pair one lighting word with one camera word and leave it there.

Put exact text in quotes

Ideogram models are known for rendering readable text — logos, posters, labels, signs. To get text right, write the exact words in quotes, keep the string short (a couple of words renders more reliably than a paragraph), and mention what it is: “a coffee shop sign that reads “OPEN””. Long blocks of exact text still trip up, so treat more than a few words as a risk and check the result.

Say what you want, not what you don't

Image models have no reliable negative prompt — writing “no cars, no people, no shadows” doesn't delete those things. Instead, describe the alternative: “an empty street at night” gets you closer than “a street with no cars or people”. If something unwanted keeps appearing, rephrase toward what should be there rather than listing what shouldn't.

Common mistakes that weaken results

1. A subject that has no qualities — add size, color, material, age, mood.
2. Conflicting instructions — “photorealistic anime” splits the model.
3. Too many elements — the model spreads attention and nothing looks finished.
4. Long exact-text strings — short quoted text renders, paragraphs garble.
5. Rewriting everything between attempts — change one variable at a time.

A reusable prompt checklist

1. Subject: a specific noun with 1–3 attributes.
2. Setting: where it is, in four words or fewer.
3. Lighting: one word or phrase that sets the mood.
4. Camera: one angle or framing word, if it matters.
5. Treatment: one consistent style direction.
