Create UHD photorealistic realistic image, no animation, no 3D image

Create UHD photorealistic realistic image, no animation, no 3D image, no Pixar style. Capture a 20-month-old boy in a vintage outfit, seated with a book in his lap, exuding a thoughtful demeanor. Use a 50mm lens for sharp details and a classic background blur. Lighting should be warm and soft, resembling late afternoon sunlight. Ensure the boy’s hand shows exactly five fingers, and the photo should have a scholarly, timeless studio quality. The image should convey wisdom and serenity.
