Imagen 4 Portrait Dual-Style Comparison: Realistic vs. Artistic

Using the same portrait subject, this piece sets up a side-by-side comparison of two prompt sets to demonstrate how Imagen 4 performs under two orientations—"realism" and "artistic stylization"—giving developers a reference for prompt phrasing when integrating text-to-image APIs. The work contains two images: one follows a documentary photography approach, emphasizing soft transitions of natural light, skin texture, and the restrained composition of a shallow-depth-of-field portrait; the other follows a painterly approach, emphasizing brushstrokes, color blocks, and decorative lighting. Both images share the same subject setup (adult figure, half-body, front-facing at a slight angle, neutral background) and change only the descriptive dimensions of texture and lighting, thereby narrowing the variables of "realism" and "artistic stylization" down to style words as much as possible. Applicable scenarios: selecting a portrait style baseline for brand visuals, character design, and social media assets; reusable as a starting-point template when debugging prompts in Google AI Studio or the Gemini API. At the field level, prompt describes the image, aspect_ratio is fixed at 3:4 to suit vertical portrait framing, and negative_prompt is used to suppress common artifacts.
