CREATE → REFINE → PERFECT

The idea

Stop asking for “a realistic image.”

The better approach is to tell Gemini what the camera sees, where the light comes from, what the subject is doing, what should remain unchanged and what the final image is actually for.

That small change turns image generation from a guessing game into a repeatable workflow.

01 Generate first.
Then repair the weak parts.

Generate Create a new scene from a detailed prompt.

Edit Change one part without rebuilding everything.

Reference Use images to guide products, people and scenes.

Refine Fix details until the image is ready to publish.

Experiment #01

The 30-second realism test

Start with a deliberately basic prompt. Then improve it. This makes it easy to understand what actually changes the result.

❌ Basic

Create a realistic person sitting in a cafe.

It tells Gemini the idea, but not enough about the photograph.

✓ Detailed

Create a natural documentary-style photograph of a young professional sitting beside a cafe window on a cloudy morning. Soft diffused daylight enters from the left. Keep the person naturally posed, with realistic skin texture, normal clothing folds and subtle environmental imperfections. 35mm photography, eye-level camera, medium shot, shallow but believable depth of field, natural colors, realistic shadows and reflections. The image should feel like a real photograph rather than a polished digital render.

DETAILED PROMPT

The point isn’t to add dozens of fancy keywords. The point is to give Gemini enough information to understand the photograph you have in your head.

Prompt Lab

The prompt formula that actually helps

Use this as a starting framework. You don’t need every line every time.

Create a [TYPE OF PHOTO] of [SUBJECT]. Environment: [LOCATION + IMPORTANT BACKGROUND DETAILS] Action: [WHAT THE SUBJECT IS DOING] Lighting: [LIGHT SOURCE + QUALITY] Camera: [ANGLE + LENS LOOK + FRAMING] Materials/details: [TEXTURES + IMPORTANT OBJECT DETAILS] Mood: [EMOTION / ATMOSPHERE] Make the scene believable with natural shadows, realistic perspective, subtle imperfections and physically consistent lighting. Do not change: [DETAILS THAT MUST REMAIN UNCHANGED]

Example

One prompt, one complete scene

Copy this

Create a photorealistic editorial portrait of a young professional standing near a large apartment window. The person is naturally looking slightly away from the camera. Soft morning daylight enters from the left and creates gentle shadows across the room. Use a natural 50mm portrait-photography look, realistic depth of field, natural skin texture, realistic hair strands and believable clothing folds. Keep the apartment slightly imperfect rather than perfectly staged. Avoid plastic skin, excessive HDR, artificial glow, extreme sharpening and unrealistic symmetry. The final result should look like a real photograph captured inside a real apartment.

Turn a plain product photo into a lifestyle shot

Upload the actual product photo first. Then make it very clear that the product itself is not supposed to be redesigned.

Product prompt

Use the uploaded product as the exact product reference. Keep the product unchanged: same shape, packaging, logo, label, printed text, proportions and colors. Place it naturally on a premium wooden table inside a modern home. Use soft natural window light, realistic contact shadows and believable reflections. The environment should support the product without covering it. Do not redesign, simplify, rewrite or replace any text on the product. Do not change its proportions.

Always inspect the final image.

AI can sometimes alter packaging, text, logos or proportions. For ecommerce, compare the generated result against the original product before publishing.

Reference workflow

Give Gemini something real to work from

A reference image can be much more useful than trying to describe every tiny visual detail in text.

Watch product reference photo for an AI image editing workflow

Reference 01

Upload the actual product, person, clothing or object you want the model to understand.

Use this image as the identity/product reference.

Reference 02

If using another image for the environment, explain its role separately.

Use this second image only as inspiration for the environment and lighting. Do not copy its subject.

Don’t regenerate everything

The real power is in repairing an image

If 90% of your image looks good, don’t throw it away because 10% is wrong. Tell Gemini to change only the weak part.

Problem

Face changed

Keep everything else unchanged. Preserve the person’s identity and facial features. Only correct the face so it matches the uploaded reference.

Problem

Hands look wrong

Correct only the hands. Make the fingers anatomically natural and proportionate. Do not change the person’s face, clothing, pose or background.

Problem

Product changed

Restore the product to match the original reference exactly. Do not change the packaging, label, logo, proportions or colors. Keep the environment unchanged.

Problem

Background looks fake

Keep the subject exactly the same. Make only the background more natural and physically believable. Match its perspective, lighting and depth to the subject.

Problem

Shadows look wrong

Keep the scene unchanged. Correct only the shadows so they follow the existing light source and look physically consistent with the objects.

Problem

Text is incorrect

Correct only the visible text. Use the exact spelling provided below: [INSERT EXACT TEXT] Do not change the layout or surrounding objects.

Visual examples

Real photos make the workflow easier to understand

Use reference photos to communicate composition, materials, lighting and product context instead of describing every detail from scratch.

ENVIRONMENT REFERENCE

Consistency trick

Same person. Different locations.

When identity matters, use a suitable reference image and tell Gemini which characteristics should stay consistent.

Reference

Upload the identity reference.

Cafe

Change the environment.

Office

Keep identity consistent.

Travel

Change location again.

Campaign

Build a complete set.

Use the uploaded reference as the identity reference. Keep the person’s recognizable facial features, hairstyle, overall age appearance and identity consistent. Create a new scene inside a modern coffee shop. Change the environment and clothing, but keep the person recognizable and visually consistent with the reference.

Content creator workflow

One idea → five pieces of content

Social media content creation setup for Instagram and Pinterest visuals

Content	Instruction
Instagram	Square editorial image with the subject centered and enough breathing room.
Pinterest	Vertical composition with a clear visual focal point.
Blog	Editorial image that communicates the article topic.
YouTube	Strong focal subject with clean negative space for text.
Advertisement	Product-focused composition with controlled lighting.

Designer trick

Tell Gemini where the text will go

If you’re making a thumbnail, poster or social graphic, don’t ask Gemini to randomly place the subject.

Create a premium realistic technology photograph. Place the smartphone on the right side of the composition. Keep the left side visually clean with a darker, simple background so a large headline can be added later. Do not place important objects behind the future text area.

Small details, big difference

10 realism details most people forget

Contact shadows Objects should visually touch the surface.

Light direction One believable source is better than random glow.

Perspective Objects should share the same camera perspective.

Texture Real materials aren’t perfectly smooth.

Imperfection Real scenes contain tiny irregular details.

Depth Foreground and background should feel connected.

Reflection Glass and metal need believable reflections.

Skin texture Avoid the perfectly smooth plastic look.

One thing you should NOT write in your article

❌ “Gemini Pro gives unlimited AI images.”

A safer and more accurate statement is:

Google AI Pro provides expanded access and higher image-generation limits, but usage limits still apply and can change.

This matters because Google’s own documentation describes image-generation and other Gemini usage limits.

Before publishing

Your final AI image inspection

Don’t publish immediately after generation. Spend 30 seconds checking the image.
