Lesson 2 of 7
Writing an image brief
8 min read
Two people open the same image tool. One types "a dog" and gets a bland, generic mutt. The other types one careful sentence and gets a photo worthy of a magazine cover. Same tool, same second. What did the second person know?
A brief, not a chat
With a chatbot you go back and forth — ask, refine, ask again. An image tool doesn't work like that. It reads your whole description at once and commits to a picture in one shot. So you don't converse your way to a good image — you brief it, like handing a photographer a shot list before the shoot, not chatting during it. Everything you don't say, the tool decides for you.
An image prompt is a brief: you say it all up front. Whatever you leave out, the tool fills in on its own — so the trick is to decide the things that matter on purpose.
The four things a brief answers
Most of a good brief comes down to four questions. Subject — what's actually in the frame? Style — a photo, a watercolor, a 3D render? Composition — how is it framed: a tight close-up or a wide shot, seen from above or at eye level? Lighting — soft morning light, harsh neon, warm candlelight? Answer those four and you've pinned down most of the picture.
Subject, style, composition, lighting — four dials that decide most of any image. Leave one blank and the tool picks for you; set it and the picture snaps toward what you meant.
Build one, watch it change
You don't have to get all four right in your head first — that's what this is for. Set each part of the brief and watch both the words and the picture change with every choice.
Every choice you make is one the tool would otherwise make at random. A brief is just making those choices deliberately — which is why the same tool hands one person a masterpiece and another a mess.
Vague in, vague out
The biggest upgrade isn't fancier words — it's specific ones. "A dog" leaves everything to chance; "a fluffy golden retriever puppy in soft morning light" pins it down. Swap empty adjectives like beautiful or nice — which tell the tool nothing — for concrete ones it can actually draw.
Borrow the words photographers and artists already use — close-up, wide shot, golden hour, shallow focus, watercolour. They're precise handles the tool was trained to understand.
The gist
- —An image prompt is a brief you commit up front, not a back-and-forth chat
- —Answer the big four — subject, style, composition, and lighting
- —Specific beats vague — concrete details pin the result down; empty adjectives don't
You want a clean, professional product photo of a red sneaker in one shot. Which prompt is most likely to get it?
