Nano Banana Results: Nano Banana produced a lively editorial-style representation of the scene with strong attention to the overall mood. The image successfully captured most prompt elements such as the white lace dress, curly hair, sunglasses, Coke cans, sneakers, and the tennis court background. The colors were vibrant, with a cinematic daylight effect that matched the professional photo shoot feel. However, the tool added an extra sneaker detail — one shoe on the model’s foot and the other placed on the floor — which was not mentioned in the prompt. The sporty pose came across as slightly stiff, and the Coke cans appeared somewhat repetitive and less realistic on close inspection. Lace textures were included but not highly refined. Overall execution time was approximately 8–12 seconds.
Seedream AI Results: Seedream generated a polished and clean editorial-style image with an emphasis on realism and professional finish. The lace detailing on the dress was more accurate, and the cinematic daylight effect gave it a magazine-cover aesthetic. The composition was sharp and natural, with smoother blending of textures compared to Nano Banana. However, some prompt details were missed — the sneakers and Coke cans were not as visible or well-rendered, and the sporty “tennis-inspired” vibe was less pronounced, leaning more towards fashion portraiture. Overall execution time was approximately 12–15 seconds.
Test Case 2: Typography and Text – Graffiti Art
Prompt Used: “Graffiti wall with the word H-O-P-E”
Nano Banana Results: Created vibrant graffiti art on a brick wall with “HOPE” spelled correctly in large bubble letters with blue-to-green gradient fill, yellow outline, and an eye symbol integrated into the design. The wall shows realistic layered graffiti with tags and other street art around it. Spray paint cans are visible on the ground, adding authenticity to the scene..
Seedream AI Results: Also spelled “HOPE” correctly in bold graffiti letters with multi-colored rainbow gradient (turquoise, yellow, orange, pink, red) and black/white outline. The concrete wall has a weathered, authentic urban appearance with other tags visible in the background. Paint drips are realistically rendered below the letters, and the 3D effect/depth is more pronounced.
Test Case 3: Professional Food Photography
Prompt Used: “Gourmet chocolate lava cake on white plate, molten chocolate flowing out, fresh raspberries and mint garnish, shallow depth of field, professional food photography lighting”
Nano Banana Results: Nano Banana created appetizing food imagery with good color saturation and composition. The chocolate lava cake was recognizable and attractive, with chocolate flow visible. However, the “molten” quality sometimes appeared static or overly perfect, lacking the organic messiness of real chocolate. The shallow depth of field was present but not as precisely controlled as specified. Lighting was pleasant but sometimes lacked the dramatic highlights and shadows characteristic of professional food photography. The raspberries and mint garnish were included but occasionally looked artificial.
Seedream AI Results: Seedream AI produced magazine-quality food photography that captured the luxurious, indulgent nature of the dessert perfectly. The molten chocolate had realistic flow physics with natural drips and pools. The shallow depth of field was precisely executed with the cake in sharp focus while the background gradually blurred, exactly as a professional photographer would achieve. Studio lighting created beautiful highlights on the glossy chocolate and captured the texture of fresh raspberries with visible seeds. The mint leaves showed individual vein details. The overall result was indistinguishable from professional food photography and would be suitable for high-end restaurant menus or culinary magazines.
Test Case 4 : Volcanic Landscape with Lava
