Gemini Native (Nano Banana) - Geração de Imagens

Melhores Práticas

  • Describe scenes, don't just list keywords: Use narrative descriptions instead of disconnected words
  • Be hyper-specific: Instead of "armor," say "ornate elven plate armor, etched with silver leaf patterns, with a high collar"
  • Use camera terminology: "wide-angle shot," "macro shot," "85mm portrait lens with bokeh"
  • Iterate and refine: Follow up with "can you make the lighting a bit warmer?"

Exemplos de Prompts e Resultados

Photorealistic Portrait:
"A photorealistic close-up portrait of an elderly Japanese ceramicist with deep, sun-etched wrinkles and a warm, knowing smile. He is carefully inspecting a freshly glazed tea bowl. The setting is his rustic, sun-drenched workshop. The scene is illuminated by soft, golden hour light streaming through a window, highlighting the fine texture of the clay. Captured with an 85mm portrait lens, resulting in a soft, blurred background (bokeh). The overall mood is serene and masterful. Vertical portrait orientation."
Result: Photorealistic portrait with bokeh
Stylized Sticker:
"A kawaii-style sticker of a red panda with a cute expression, bold clean outlines, simple cel-shading, pastel colors, transparent background perfect for stickers"
Result: Kawaii red panda sticker
Product Mockup:
"A high-resolution, studio-lit product photograph of a minimalist ceramic coffee mug in matte black, presented on a polished concrete surface. The lighting is a three-point softbox setup designed to create soft, diffused highlights and eliminate harsh shadows. The camera angle is a slightly elevated 45-degree shot to showcase its clean lines. Ultra-realistic, with sharp focus on the steam rising from the coffee. Square image."
Result: Product mockup with studio lighting
Image Editing - Logo Addition:
"Take the first image of the woman with brown hair, blue eyes, and a neutral expression. Add the logo from the second image onto her black t-shirt. Ensure the woman's face and features remain completely unchanged. The logo should look like it's naturally printed on the fabric, following the folds of the shirt."
Input 1: Woman portrait Input 2: Logo Result: Portrait with logo on shirt
E-Commerce Fashion Photo:
"Create a professional e-commerce fashion photo. Take the blue floral dress from the first image and let the woman from the second image wear it. Generate a realistic, full-body shot of the woman wearing the dress, with the lighting and shadows adjusted to match the outdoor environment."
Input 1: Blue floral dress Input 2: Model Result: Model wearing dress outdoors
Image Editing - Object Replacement:
"Using the provided image of a living room, change only the blue sofa to be a vintage, brown leather chesterfield sofa. Keep the rest of the room, including the pillows on the sofa and the lighting, unchanged."
Input: Living room with blue sofa Result: Living room with brown leather sofa
Image Editing - Add Accessory:
"Using the provided image of my cat, please add a small, knitted wizard hat on its head. Make it look like it's sitting comfortably and matches the soft lighting of the photo."
Input: Cat photo Result: Cat with wizard hat

💡 Pro Tip: Gemini excels at multi-image editing and combining elements from different sources. Be specific about which elements to keep unchanged and how to blend new additions naturally.

Diálogo e Efeitos Sonoros

Prompt: "A close up of two people staring at a cryptic drawing on a wall, torchlight flickering. A man murmurs, 'This must be it. That's the secret code.' The woman looks at him and whispering excitedly, 'What did you find?'"

Realismo Cinematográfico

Prompt: "Drone shot following a classic red convertible driven by a man along a winding coastal road at sunset, waves crashing against the rocks below. The convertible accelerates fast and the engine roars loudly."

Animação Criativa

Prompt: "A whimsical stop-motion animation of a tiny robot tending to a garden of glowing mushrooms on a miniature planet."

Geração de Imagem para Vídeo

Transform static images into dynamic videos. Upload a reference image and describe the motion, camera work, and atmosphere you want to create.

Using Reference Images:
The video opens with a medium, eye-level shot of a beautiful woman with dark hair and warm brown eyes. She wears a magnificent, high-fashion flamingo dress with layers of pink and fuchsia feathers, complemented by whimsical pink, heart-shaped sunglasses. She walks with serene confidence through the crystal-clear, shallow turquoise water of a sun-drenched lagoon. The camera slowly pulls back to a medium-wide shot, revealing the breathtaking scene as the dress's long train glides and floats gracefully on the water's surface behind her. The cinematic, dreamlike atmosphere is enhanced by the vibrant colors of the dress against the serene, minimalist landscape, capturing a moment of pure elegance and high-fashion fantasy.
Reference image: Flamingo Reference image: Woman with flamingo Reference image: Flamingo with glasses

Interpolação - Usando Primeiro e Último Quadros

Create smooth transitions between two images by providing a first frame and last frame. Veo generates the in-between frames to create a seamless video transition.

Example: Ghost girl to empty tree transition
First frame: Ghost girl Last frame: Empty tree Result: Interpolated video transition

Essential Prompt Components

  • Subject & Action: What's happening in the scene (people walking, car driving, robot gardening)
  • Camera Work: Shot types and movement (drone shot, close-up, tracking shot, aerial view)
  • Style: Visual aesthetic (cinematic, stop-motion animation, realistic, stylized)
  • Lighting & Atmosphere: Time of day, mood, weather (sunset, torchlight, golden hour)
  • Audio: Dialogue, sound effects, ambient sounds (engine roaring, waves crashing, whispering)

🎬 Pro Tips: Keep dialogue short (~8 seconds maximum). Layer multiple audio elements (dialogue, ambient sounds, music). Specify camera movements (dolly shot, drone view, tracking shot). Add "(no subtitles)" if you want dialogue without text overlay. Be specific about camera movements, sound details, and atmosphere. For image-to-video, describe the motion you want to see from the static image. Choose aspect ratio: 16:9 (widescreen) or 9:16 (portrait)

Fast 3D - Imagem para Modelo 3D

Melhores Práticas para Imagens de Origem

  • Clear subject: Single object with clear edges and definition
  • Good lighting: Even lighting without harsh shadows
  • Clean background: Solid or simple backgrounds work best
  • Multiple angles: Front-facing objects convert more accurately
  • High contrast: Clear distinction between object and background

O Que Funciona Bem

  • Products and objects (shoes, furniture, gadgets)
  • Characters and creatures (toys, figurines)
  • Architectural elements (buildings, structures)
  • Vehicles (cars, bikes, spacecraft)

Formatos de Saída

  • GLB: Best for web and AR applications, includes textures
  • STL: Perfect for 3D printing, geometry only

Exemplo: Conversão de Imagem para 3D

Process: Upload a 2D image of a cup and Fast 3D converts it into a fully textured 3D model in seconds.
Original 2D image of a cup
Input: 2D Image of Cup
Output: Interactive 3D Model (Drag to rotate)

💡 Workflow Tip: Generate your ideal product image with Imagen first, then convert it to 3D with Fast 3D for consistent, high-quality 3D assets. The resulting 3D models can be viewed in any GLB viewer or imported into 3D software like Blender.
