Module 3: Mastering Visual Styles with Gemini in Google Slides

In this module, you will learn how to move beyond generic image generation by mastering Style Controls. Choosing a consistent visual style is the difference between a deck that looks "pieced together" and one that looks like a professionally designed brand experience. Gemini allows you to dictate the artistic DNA of your presentation using specific stylistic keywords and parameters.
1. The Importance of Stylistic Consistency
A presentation is a visual narrative. When your slides jump from 3D cartoons to gritty black-and-white photography, the audience experiences "cognitive friction."
Brand Alignment: Align your imagery with your company’s existing design language (e.g., "Minimalist" for tech, "Classic Photography" for finance).
Emotional Resonance: Different styles evoke different feelings. A "Watercolor" style feels approachable and human, while a "Vector Illustration" feels precise and modern.
Professionalism: Uniformity in style suggests attention to detail and high production value.
2. Primary Style Categories in Gemini
When using the "Create an image" side panel in Slides, you can explicitly request these foundational styles to set the tone for your deck:
A. Photorealistic & Photography
Best for establishing credibility, realism, and human connection.
Keywords: Macro photography, wide-angle lens, soft bokeh background, natural lighting, high-resolution.
Example Prompt: "A professional team collaborating in a sunlit modern office, photorealistic style, shallow depth of field."
B. Vector & Flat Illustration
Best for explaining complex concepts, software tutorials, or maintaining a "clean" tech aesthetic.
Keywords: 2D vector, flat design, bold outlines, vibrant colors, isometric view.
Example Prompt: "An isometric vector illustration of a cloud computing network, clean lines, blue and white color palette."
C. 3D Render & Skeuomorphism
Best for product mockups, futuristic themes, or adding "depth" to a slide.
Keywords: 3D isometric, Octane render, soft shadows, matte texture, Unreal Engine 5 style.
Example Prompt: "A 3D render of a golden trophy on a marble pedestal, soft studio lighting, high detail."
D. Artistic & Abstract
Best for title slides, transition slides, or representing intangible concepts like "Innovation" or "Speed."
Keywords: Watercolor, oil painting, charcoal sketch, abstract geometric, cyberpunk aesthetic.
Example Prompt: "An abstract digital painting representing 'global connectivity,' flowing lines, neon accents."
3. Refining Style with "Modifier" Keywords
Once you’ve chosen a base style, you can refine the "flavour" of the image using specific modifiers.
4. Workflow: Building a "Style Guide" for Your Deck

To ensure your course content remains cohesive, follow this 3-step workflow:
Define the Anchor: Create your first image (e.g., for the Title Slide) and refine the prompt until the style is perfect.
Extract the "Style String": Identify the keywords that made that image work (e.g., "Flat vector illustration, pastel colors, minimalist").
Apply the String Universally: Copy and paste those exact style keywords at the end of every subsequent image prompt in that deck.
5. Troubleshooting Style "Drift"

Sometimes the AI may interpret a prompt too literally and lose the style. If your images start looking inconsistent:
Weight the Style: Move the style keywords to the beginning of the prompt.
Reference Previous Results: If an image is off, click "Edit" and explicitly tell Gemini: "Same style as the previous image, but change the subject to a laptop."
Simplify: Remove competing adjectives. If you ask for "Gritty" and "Soft" in the same prompt, the AI may produce a confusing middle ground.
Style Selection Checklist
[ ] Does the chosen style align with the Subject Matter?
[ ] Have I used the same Style String for at least 3 consecutive slides?
[ ] Is the Color Palette consistent across the generated images?
[ ] Does the style allow for Text Readability when placed on the slide?
