Underwater AI Model Comparison

Goal: Create a wide side-by-side comparison image showing two underwater snorkeling photos of the same scene, as if comparing model outputs.

Canvas: Horizontal 2:1 aspect ratio on an off-white background, with two large rectangular photo panels placed side by side and separated by a narrow vertical gutter. Add small black bold labels above the panels: left label reads {argument name="left label" default="GPT Image 2"}, right label reads {argument name="right label" default="GPT Image 2.5"}.

Layout: Use exactly 2 photo panels. The left panel occupies the left half and the right panel occupies the right half. Keep the labels aligned near the upper-left corner of each panel. No borders other than the off-white background margin and the central gap.

Subject details: Both panels show a realistic underwater wide-angle action-camera photograph in clear tropical turquoise water. The subject is {argument name="subject" default="a young woman snorkeler"} wearing a black wetsuit or rash guard, a large black snorkel mask, and black fins. She is swimming horizontally toward the camera just below the rippling water surface. Sunlight creates bright caustic patterns across the shallow sandy seabed. Small fish are visible in the blue water, and coral or rocky reef formations appear near the edges.

Left panel: The snorkeler is centered and closer to the camera, facing forward with arms tucked back, body streamlined, black mask dominating the face. The water is bright cyan, the sandy bottom is shallow and patterned with sun ripples, and a small reef rock sits in the lower-left foreground. The overall look is clean, slightly artificial, and symmetrical.

Right panel: The snorkeler is angled diagonally from lower center toward upper left, with one arm extended toward the camera in a selfie-like perspective. Her fins are visible behind her near the top-left area, and larger reef rocks appear on the right side. The water has richer color contrast, stronger surface shimmer, more fish in the background, and a more dynamic wide-angle composition.

Visual style: Photorealistic underwater photography, natural sunlight, crisp details, GoPro-style wide-angle lens, high clarity, realistic water refraction, vivid aquamarine and sandy white tones.

Constraints: Include exactly 2 labeled panels and exactly 2 visible text labels. Do not add extra captions, watermarks, UI elements, arrows, or decorative graphics.
