Turn an idea into a good image prompt

Lesson 3 of 55 min read1 task · 3 questions

Say what is in the picture, how it looks and what must not be there.

The idea

Free image tools exist inside several chatbots. A weak image prompt is "nice office photo". A strong one names five things: subject, setting, style, camera or framing and mood or colours.

Add an avoid line for things you do not want, for example "no text, no logos". AI images often spell words wrongly. Add real text later in a free editor such as Canva or your phone's photo app.

Never make an image of a real person without their permission. Use made-up people or objects for your posts. The quality of free tools and their limits change often, so try two tools and keep the better result.

Your task

Ask the chatbot to write the image prompt for you

You do not need to be a prompt expert. Let the chatbot write the image prompt. Then paste that into an image tool.

Your slip: copy-paste prompt
I need a background image for a social media post about saving time at work. Write one detailed image prompt I can paste into an image generator.

Include these 5 parts as one flowing paragraph: subject, setting, style, framing, colours and mood.
Idea: a neat desk with a laptop showing a simple spreadsheet, a cup of tea and a small clock.
Style: clean flat illustration.
Format: square, with empty space at the top for text.
Add an "Avoid:" sentence at the end. Do not include any real person or brand.
Give me only the prompt.

What you should get

A real example of a good result. Your wording will differ a little. The shape and the facts should match.

Printed resultExample

A neat wooden desk seen from slightly above, with an open laptop showing a simple colourful spreadsheet, a steaming cup of masala tea and a small round clock, in a bright, tidy home-office setting. Clean flat illustration style with soft shapes and smooth shading. Square framing with the objects at the bottom and a large empty area at the top for text. Warm colours: soft orange, cream and teal, with a calm, friendly mood. Avoid: real people, logos, brand names, readable text and clutter.
