4K AI Editing in Photoshop 2026: Nano Banana 2 Pro, Seedream & Luminel

Video Description

Get the 4K AI Photoshop Plugin ⤵️ https://Luminel.ai In this video, I turn Photoshop into a 4K AI editing machine with Nano Banana Pro 4K & Seedream 4.0 and show my workflow for building creatives and fashion campaigns with AI. I install the 4K plugin, connect the Replicate API key, and use reference images (clothes, accessories, cars, interiors) for precise control. You’ll see outfit and pose changes on the same model, clean e-commerce conversions, editorial interiors, eye and glasses fixes, and a comparison of Seedream, NanoBanana, and Flux. In the end, we build a surreal fashion campaign scene with a car wash, horse, vintage car, and the model perfectly integrated. Tools & Workflows Used ⤵️ Photoshop 4K AI Plugin — https://Luminel.ai Nano Banana Pro 4K ( best model on the market ) Seedream 4.0 (4K image editing and generation) NanoBanana (concept generations and smaller fixes) Flux Pro / Flux Max (comparison for detail and skin) Qwen Image Edit (precise local edits like sunglasses) Replicate API (cheap, direct access to AI models inside Photoshop) Why Watch? I’m Kai, and I use AI to create real-world fashion and campaign visuals directly in Photoshop. This video is a practical workflow you can copy – from reference-based outfit changes and editorial interiors to fixing eyes, reflections and building surreal campaign images. If you want to use AI seriously for client work and creative business, this is how I actually do it.
