The Exact AI Image Prompts and Settings We Used

We used the following prompts to generate images for cover realistic photography, product advertising, illustration, and controlled editing.

Test 1: Photorealistic lifestyle image

What to look for: Believable anatomy, natural skin and hair, consistent lighting, realistic textures, and accurate object placement.

Prompt ✍️

Create a photorealistic editorial lifestyle photograph of one fictional adult woman in her early 40s, seated at a weathered wooden table in a leafy backyard garden. She has shoulder-length curly dark hair, subtle freckles, and visible natural skin texture. She wears an unbranded olive-green linen shirt with loosely rolled sleeves.

Place her in the left third of the square composition, framed from the waist up at eye level. Her right hand holds the handle of a plain cream ceramic mug resting on the table. Her left hand rests flat beside an open notebook with no readable writing. Keep both hands fully visible.

Use soft morning sunlight from the upper left, gently illuminating her face and creating consistent shadows beneath the mug and her arms. Include individual flyaway hairs, fine fabric creases, ceramic texture, and visible wood grain.

Keep garden foliage recognizable but softly out of focus. Aim for a professionally lit, candid photograph with natural colors and realistic proportions. No additional people, logos, watermarks, beauty filters, or exaggerated skin smoothing.


Test 2: Product and commercial image

What to look for: Product geometry, material accuracy, controlled reflections, clean composition, and usable space for advertising copy.

Prompt ✍️

Create a premium studio advertising photograph of a fictional, unbranded reusable water bottle. The bottle has a straight cylindrical body made from matte forest-green powder-coated stainless steel, a brushed silver screw cap, and a narrow black silicone ring beneath the cap. Keep the construction physically plausible, with consistent edges and a level base.

Show one bottle standing upright on a low, rectangular pale limestone pedestal in the right third of a square composition. Use a three-quarter camera angle at approximately the bottle’s midpoint. Keep the entire bottle and pedestal visible.

Use a seamless warm ivory background. Leave the left 40 percent of the image empty and evenly lit for optional marketing copy. Place no props or decorative elements in that space.

Light the scene with a large softbox from the upper left and a subtle rim light from behind on the right. Show restrained metallic reflections, fine limestone pores, and a soft contact shadow beneath the bottle. The bottle should be the sharpest, most prominent element. No text, logos, labels, droplets, or additional products.


Test 3: Creative illustration and art direction

What to look for: Visual storytelling, a coherent palette, clear focal points, atmospheric depth, and consistent illustration style.

Prompt ✍️

Generate a cinematic editorial illustration of a fictional adult lighthouse keeper tending a small rooftop garden above a sea of clouds at dusk. The garden sits on a circular stone platform attached to an isolated lighthouse. The keeper wears a mustard-yellow raincoat and carefully waters a single luminous flowering plant.

Build a clear visual story around protecting something fragile in a vast, lonely environment. Place the keeper and glowing plant in the lower-right third of the square composition. Position the lighthouse along the left edge, with its upper section extending beyond the frame. A curved stone railing should guide the viewer’s eye toward the plant.

Use deep indigo, muted teal, and warm amber as the dominant palette. The plant casts a gentle amber glow on the keeper’s hands and face. Cool twilight illuminates the clouds, with distant mountain peaks breaking through.

Render the scene as a painterly digital illustration with visible brush texture, carefully defined focal details, and softer atmospheric distance. Keep the mood quiet, hopeful, and slightly mysterious. Avoid photorealism, additional characters, text, logos, and recognizable fictional properties.


Test 4: Reference image and controlled editing

What to look for: Preservation of facial identity, pose, framing, and untouched details, alongside accurate changes to the requested elements.

Prompt ✍️

Edit the supplied reference image while preserving the person’s identity and the original photographic style. Keep their facial structure, apparent age, skin tone, eye color, hairstyle, hairline, expression, and gaze unchanged. Preserve their exact pose, hand positions, body proportions, camera angle, framing, and position within the image.

Make only two intentional changes. First, replace the background with a realistic botanical greenhouse containing softly blurred leafy plants and a glass-and-metal structure. Second, change the jacket to muted navy blue while retaining its original cut, material, seams, buttons, folds, and fit.

Match the new background’s light direction and color temperature to the original lighting on the person. Keep the subject’s face and skin texture unchanged. Preserve fine hairs and clean, natural boundaries around the shoulders and hands.

Do not add accessories, alter other clothing, smooth the skin, reshape facial features, change the expression, or crop the image. Return one edited photograph without text or watermarks.


Why the Best AI Image Generator Depends on the Job

An AI image generator that’s best for a product launch may not be as good for an illustrated story. One model could do better than another in a certain area, but you have to pick what works best for what you need to make.

You should think about the following criteria before choosing an image model or models: 

  • Realism and products: Focus on believable lighting and product details.

  • Rapid brainstorming: Favor speed so you can explore more ideas.

  • Editorial art direction: Look for mood, storytelling, and style control.

  • Graphic-design assets: Concentrate on composition, readable text, and consistent colors.

  • Image editing: Choose precise changes that preserve untouched areas.

  • Reference transformations: Prioritize recognizable people, objects, and visual details.

Use overall scores to build your shortlist, then compare the strengths that matter to your project.

Why You Should Not Limit Yourself to One AI Image Model

Your first concept and final campaign image may need different strengths. Lorka AI’s image generator brings the top image models from Google, OpenAI, and more into one workspace, giving you options as your project develops.
