The Take

Prompt complexity matters, but not how you’d expect. The detailed prompts produced cleaner product shots but killed creativity. Simple prompts let models show personality—some good (imaginative colorways), some bad (impossible geometry).

Nanobanana 2 won both approaches with clean geometry and realistic proportions. GPT Image 2’s 43-52 second generation times remain a dealbreaker despite decent quality. The bike packing variation proved simple prompts can be more fun—models got creative with bags, routes, and adventure vibes.

Variation 1

Road Bike (Detailed Prompt)

Highly detailed prompt specifying exact geometry, components, and photography style

The Prompt

Create a professional product photography shot showing the perfect side profile geometry of a high-end road racing bike. The bike should be positioned on a clean white or light gray background, perfectly level, showing the complete side view to display: head tube angle, seat tube angle, top tube length, wheelbase, and bottom bracket drop. The bike should be a modern aero road bike with deep section carbon wheels, electronic shifting (visible rear derailleur), and aggressive racing geometry. Lighting should be clean and even with subtle shadows to show depth and tube profiles. No rider, no distractions - pure geometry showcase. Think product catalog photography meets engineering diagram. Shot on medium format camera, tack sharp from front to back, editorial product photography style.

The Take

Detailed prompt produced catalog-ready shots from Nanobanana 2 — clean white background, proper side profile, realistic proportions. The extra detail constrained creativity but ensured technical accuracy. Most models followed instructions but lost personality in the process.

Variation 2

Mountain Bike (Detailed Prompt)

Highly detailed prompt specifying suspension, geometry, and technical details

The Prompt

Create a professional product photography shot showing the perfect side profile geometry of a high-end full-suspension mountain bike. The bike should be positioned on a clean white or light gray background, perfectly level, showing the complete side view to display: slack head tube angle, steep seat tube angle, long reach, short chainstays, and full suspension linkage design. The bike should be a modern enduro/trail bike with 150-160mm travel, dropper post fully extended, 29-inch wheels with aggressive knobby tires, and visible suspension components (fork and rear shock). Lighting should be clean and even with subtle shadows to show the frame's sculpted tubes and suspension design. No rider, no action - pure geometry and engineering showcase. Think product catalog photography meets technical spec sheet. Shot on medium format camera, tack sharp throughout, editorial product photography style.

The Take

Suspension geometry exposed which models actually understand bikes. Nanobanana 2 nailed the linkage design and slack angles. Most others produced generic “mountain bike” shapes that wouldn’t actually work. Detailed prompts helped but couldn’t fix fundamental geometry ignorance.

The Take

80s frankenbike prompt unleashed peak chaos — Nanobanana 2 delivered radical colors and bizarre mods while keeping the bike functional. Most others went full cartoon or forgot geometry exists. When the prompt says “bizarre and awesome,” models that understand bikes can be creative without breaking physics. Those that don’t just make colorful nonsense.
