Short answer
A free guide to prompting for AI image generation in 2026: the parts of a great image prompt, subject, setting, composition, lighting, camera and lens, style, color, text in images, aspect ratios, reference images, editing prompts, model differences, examples, and rules.
Modern image models, such as Nano Banana 2.1, GPT Image 2.5, FLUX 3 Image, and Midjourney, understand full sentences. Describe the image the way you would brief a photographer or illustrator: clearly and specifically.
If you can see it clearly, you can describe it clearly.
02
Cover the parts of a strong image prompt
Subject
Who or what, with the key details
Action
What the subject is doing
Setting
Where and when
Composition
Framing and camera angle
Lighting
Type, direction, and mood of light
Style
Photo, illustration, 3D, or painting
Color
Palette and color grade
Format
Aspect ratio and intended use
03
Make the subject specific
Vague
A woman in a cafe
Specific
A woman in her 30s, with short curly hair and a green wool coat, reading a paperback at a window table in a small Paris cafe
04
Set the composition and camera
Shot size: close-up, medium shot, or wide shot
Angle: eye level, low angle, or top-down
Lens: 35mm for a natural look, 85mm for portraits, wide-angle for drama
Depth of field: shallow to blur the background
Placement: subject on the left, room for text on the right
05
Choose the lighting and mood
Golden hour, soft window light, or a studio softbox
Hard sunlight for strong contrast
Neon or candlelight for a moody atmosphere
A named mood: calm, tense, joyful, or mysterious
06
Define a style without copying artists
Describe the style in your own words rather than naming living artists:
“Flat vector illustration with bold outlines”
“Soft watercolor with visible paper grain”
“Realistic product photo on a plain white background”
“Cinematic film still with muted colors”
07
Add text to images
Put the exact words in quotes
State where the text sits and how it looks
Keep the text short
Proofread the spelling in every result
A bold poster reading “SUMMER SALE” in large white letters across the top, on a bright coral background.
08
Pick the aspect ratio
1:1
Feeds and profile pictures
4:5
Instagram and Facebook feeds
9:16
Stories, Reels, and phone wallpapers
16:9
Thumbnails, banners, and slides
09
Use reference images
Upload a product or character image to keep it consistent across images
Name what stays: “Keep the product, label, and colors unchanged”
Name what changes: background, lighting, or outfit
Reuse the same references across a whole series
10
Edit with focused prompts
Change one thing per edit
“Turn the sky into a sunset and keep everything else the same”
“Remove the person in the background”
“Make the jacket navy blue”
11
Study a full example
A close-up product photo of a matte black water bottle on a wet granite rock beside a mountain stream, morning mist, soft side lighting, shallow depth of field, cool blue and green tones, realistic, room for text on the left, 4:5.
12
Use images responsibly
Do not make realistic images of real people without their consent
Do not copy existing logos, characters, or brands
Label realistic AI images wherever platforms require it
Read each tool’s commercial-use terms
The golden rule
Do not type a few words and hope. Describe the subject, setting, light, style, and format. Then refine one change at a time.
Subject
Setting
Camera
Light
Style
Text

Take your last image prompt, add camera, lighting, and format details, and compare the two results.
