Midjourney is the strongest fit for generating professional, studio-quality product images without a physical shoot. You can describe your product, lighting setup, background, and style in a prompt and iterate quickly until the result looks polished enough for an e-commerce listing. Its photorealistic rendering and fine control over composition make it a go-to for commercial imagery. Flux is worth considering if you prefer a pay-as-you-go model with strong photorealism at a lower entry cost, and DALL-E integrates directly with ChatGPT Plus if you want to combine image generation with copy editing in one subscription.
