Stock Photography — Side-by-Side Results
Prompt
"A diverse woman in her mid-20s with shoulder-length curly dark hair, wearing a soft beige hoodie and high-waisted jeans, holds her phone at arm’s length for a casual selfie while glancing near the camera with a relaxed half-smile. She’s seated by a window in a bright neighborhood café with a latte and an open laptop on the table, candid “work day” vibe, clean stock-photo composition. Natural window light, minimal background clutter, realistic phone-camera perspective like an Instagram story."

Flux 2 Strengths
- Flexible stock workflows with both text-to-image and image-to-image editing for iterative, brief-driven variations
- LoRA support for building consistent stock “series” (same talent, wardrobe, lighting, or brand look across many assets)
- Up to 4MP output for sharper crops and multi-use deliverables (web, social, and many common stock resolutions)
- Style transfer and controlled look adjustments to match established stock aesthetics (bright lifestyle, clinical product, editorial, etc.)
- Face-swap support for creating multiple talent variants or localization while keeping composition consistent
Flux Ultra 1.1 Strengths
- Exceptional photorealistic detail that helps images read as authentic stock photography at first glance
- Premium-quality outputs that often require fewer retries for hero images and high-scrutiny use cases
- Strong performance for close-ups and texture-heavy scenes (food, materials, product surfaces, skin detail)
- Efficient per-image pricing (16 credits) for high-end results without an added premium tier
Verdict
Choose Flux 2 when your stock work depends on repeatable series, controlled variations, and post-generation adjustments. Its editing tools and LoRA support make it well-suited to building cohesive collections (e.g., “remote work,” “healthcare,” “small business,” “travel”) with consistent subjects and art direction.
Choose Flux Ultra 1.1 when you want premium photorealism with minimal iteration—especially for hero assets where micro-detail and a natural photographic feel matter most. If your priority is the most realistic output per credit, Flux Ultra 1.1 is a compelling option.
