Prompt Engineering Basics: The 5-Part Prompt Formula

Guides7 min read

The short answer

A reliable AI-image prompt has five parts: subject (exactly what), style (the visual language), scene (where and what's around), light (time, source, mood), and camera (angle, lens feel, ratio). On Etch, where each finished image costs ₹15, a complete prompt wastes fewer generations: specificity in, accuracy out. Write all five parts before you order, and iterate on one part at a time.

Most bad AI images aren't the model's fault — they're the prompt's. “A beautiful product photo” could mean a hundred things, so the AI picks one at random and you pay for the lottery ticket. Prompt engineering sounds technical, but it's just structured describing: give the model the five decisions it can't make for you, and it stops guessing. At ₹15 per finished image, every avoided re-roll is money kept.

The five parts, with an example

Here's a complete prompt built with the formula — a D2C candle brand's hero shot:

Common mistakes, fixed

MistakeWhy it failsFix
“Make it premium”Vague — premium means different thingsName the cues: “matte black, gold foil accents, dark background”
Contradictory adjectives“Cozy yet dramatic” pulls two waysPick one mood per generation
Forgetting the backgroundAI fills the void randomlyAlways include the scene part
No negative guidanceUnwanted elements appearAdd “no hands, no watermark, no extra objects”

Indian-context prompting: be specific, get specificity

Generic prompts produce generic imagery — often Western-default. “A family celebrating” tends toward imagery that doesn't look like your audience. Name the specifics: “a North Indian family celebrating Diwali, marigold torans on the door, diyas on the balcony railing, evening”. Festivals, clothing, architecture, street scenes — the model knows them, but only if you ask. This is the cheapest quality upgrade in AI imagery: ten extra words of cultural specificity.

The same applies to products. “Ayurvedic face oil” gets you a prettier result than “face oil” because it anchors the styling — brass bowls, neem leaves, warm wood. Your product's context is a prompt asset; spend it.

Iterating without burning money

Treat generation like a conversation, not a slot machine. First order: your best five-part prompt. Review against the brief part by part — subject right? light wrong? Then revise only the failing part. The ₹49 4-pack is the iteration tool: four variants of one concept in a single order, so you can test “morning light vs evening glow vs studio softbox vs golden hour” side by side instead of guessing sequentially. Check the pricing page for the full menu.

Steal this template

Copy, fill, generate: “[SUBJECT with exact details], [STYLE / visual language], [SCENE with surroundings], [LIGHT with time and mood], [CAMERA angle and crop]. No [things to avoid].” Keep a running doc of prompts that worked — your best prompts are reusable assets. A seller with forty SKUs and one proven prompt template has a catalog; a seller re-rolling from scratch every time has a hobby. Review your template quarterly: as your brand evolves, the style and light parts are usually what need updating, while subject and camera stay constant.

Frequently asked questions

What is the 5-part prompt formula?

Subject, style, scene, light, camera. Subject: the exact thing (“hand-poured soy candle in amber glass”). Style: the visual language (“warm lifestyle photography”). Scene: surroundings (“on a light oak table beside dried flowers”). Light: (“soft morning window light”). Camera: (“straight-on, shallow depth of field”). Five parts, one complete instruction.

How long should my prompt be?

Long enough to cover all five parts — usually two to four sentences. One vague sentence (“a nice candle photo”) forces the AI to guess; a paragraph of purple prose adds noise it will interpret literally. Aim for precise and plain: concrete nouns beat adjectives.

What if the first image isn't right?

Change one part at a time. If the composition is good but the mood is wrong, keep subject/scene/camera and rewrite only the light and style. On Etch a remake costs ₹5, and the ₹49 4-pack lets you test four variations of one part in a single order.

Do I need to learn prompt engineering to use Etch?

No — describe what you want in plain words and the system handles the rest. But the five parts help you describe it better: most disappointing results come from under-specified briefs, not from the technology. Ten minutes with this formula noticeably improves first-try results.
