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 12-month-old boy dressed as a medieval knight, holding a toy sword with a playful grin. Use a 50mm lens for sharp detail and soft bokeh background. Lighting should mimic natural daylight with subtle highlights on the armor. Ensure the photo has a family album studio feel, with the boy's hand showing exactly five fingers. The image should convey a sense of fun and adventure.
