How to Create AI Images for Beginners (A Simple Guide)

How it works, in one paragraph

You type a description and a picture appears. Underneath, the tool learned what words look like from an enormous number of captioned images. It starts with random visual noise and repeatedly nudges that noise toward whatever matches your description.

One consequence explains most beginner frustration: the model is matching your description against patterns, not following instructions like a person would. If you say "no dog", the word dog is still in there and a dog may well appear. If you leave something out, it does not ask; it fills the gap with the most average version of that thing it has seen.

That is the whole skill. Say what you want specifically, and say what you do not want in the place designed for it.

The six-part formula

Nearly every good image prompt contains the same six things. Missing ones get filled with defaults, and the defaults are exactly what makes an image look generic.

Part	What to say	If you leave it out
Subject	The specific thing, with the details that matter	The most generic version of that noun
Setting	Where it is, and how much you see	A blank or cluttered background
Lighting	Time of day, direction, quality	Flat, evenly lit, lifeless
Framing	Close up or wide, from what angle	A centred medium shot, every time
Style	Photograph, oil painting, 3D render, illustration	Glossy digital art
Mood or colour	The feeling and palette	Oversaturated and high contrast

A weak prompt: a cozy living room.

A strong prompt: A small living room with a lit fireplace and a tabby cat asleep on a worn armchair, late afternoon light through a west-facing window, wide shot from the doorway, realistic photograph, 35mm, warm browns and soft amber, calm and lived in.

Both take about the same effort to think of. The second one is a picture; the first is a category.

Then add the part beginners skip entirely: a negative list. Negative: text, watermark, extra fingers, cluttered background, stock-photo smiling. Most of what makes an image look AI generated comes from a small set of recurring artefacts, and naming them removes them.

The trick that makes this easy

You do not have to write these prompts yourself. Ask a text AI to write them for you.

Write an image generation prompt for: [your rough idea]. It is for [purpose]. Structure it as subject, setting, lighting, framing, style, colour and mood, then a negative list. Give me three versions that differ in framing rather than in adjectives.

Language models are considerably better at writing image prompts than most people are, because the format is a known one and they have seen enormous numbers of examples. This is why generating images inside a chat is genuinely more useful than a standalone image box: the tool that writes the prompt is sitting right next to the one that draws it.

Why your image came out wrong

A short diagnostic list covering nearly every beginner problem.

Boring and generic. You did not specify lighting or framing. Those two do more work than any other pair.

The right things, arranged wrongly. Say the framing explicitly: wide shot from below, close up, subject in the left third. The model has no idea where you want things unless you say.

Something you asked not to see is in the picture. Naming it in the main prompt makes it more likely, not less. Move it to the negative list.

Hands, faces, or small repeated details are wrong. Still the weakest area everywhere. Try a closer crop, a different angle, or hands not being visible. Sometimes just regenerate.

Text is gibberish. Expected. See the next section.

It looks like stock photography. Add candid, describe an action rather than a pose, and put stock-photo smiling at camera in the negatives.

Wrong shape for where you need it. Ask for the aspect ratio you actually need. Cropping a square into a banner throws away the composition you asked for.

Iterating without going round in circles

Beginners regenerate the same prompt hoping for a better roll. Some randomness is unavoidable, but most wasted attempts come from changing several things at once.

• Change one thing per attempt. Lighting, or framing, or style. Not all three, or you will not know what helped.
• Fix composition before detail. Getting the framing and light right first is far more efficient than perfecting a subject that is in the wrong part of the frame.
• Describe what was right. When an image is close, say so in words in the next prompt rather than assuming the tool remembers.
• Save prompts that worked. Six or eight reliable prompt shapes are worth more than any single image, and they are what make a set of pictures look like they belong together.

What it still cannot do

Text. Words in images remain unreliable everywhere. A short word sometimes works; a headline or a logo usually does not. Generate the picture clean and add text in any design tool, which also gets you the right font.

Exact arrangements. "Exactly three objects, the red one on the left" is not reliably followed. If the arrangement matters, generate the pieces and compose them yourself.

The same character twice. Getting an identical person or product across a series is difficult. Detailed repeated descriptions help and identical results are not guaranteed.

Editing a real photo precisely. It can adjust background, lighting, and style well. It cannot reliably move an object two inches to the left.

And on using the results: check the rules before anything generated goes somewhere commercial. Take particular care with images resembling a real person, a recognisable place, or the distinctive style of a living artist. Terms differ between tools and the responsibility sits with whoever publishes the image.
