Prompting Guide

How to create a better AI image prompt

A useful prompt gives the model a clear subject, visual direction, and technical constraints without burying the idea in random keywords.

Start with the subject

Name the person, object, environment, or action clearly. Specific visual nouns work better than vague concepts.

Control the visual language

Add the style, composition, lighting, colors, and mood that directly support your intended result.

Iterate after generation

Generate once, identify the biggest problem, then change one or two instructions instead of rewriting everything.

Goal	Weak prompt	Stronger direction
Product image	“A watch on a table”	Define the watch materials, surface, studio lighting, camera angle, reflections, and clean commercial background.
Portrait	“A cinematic woman”	Describe age range, clothing, expression, setting, lens, framing, key light, color grade, and atmosphere.
Thumbnail	“YouTube thumbnail about AI”	Specify one focal subject, bold contrast, negative space for a short headline, expressive emotion, and 16:9 framing.
Logo concept	“A modern logo”	Name the brand idea, geometry, symbol, line weight, color limit, flat vector style, and what to avoid.
