С цветными изображениями лучший результат дает Nano Banana Pro, с ч/б - Seedream 5. Можно использовать также с chatGPT Image 2.
Transform the uploaded phone photo into a single-sheet flatbed scan on pure white — preserve every drawn detail exactly; apply only geometric correction, background unification, and maximum sharpness. No blur, no soft edges, no redesign.
