Ultra-Realistic Baby Cake Photo Description

Create an ultra-realistic DSLR-style photograph image description of a 1-year-old boy with rosy cheeks and soft, natural skin texture blowing out a single candle on a homemade vanilla cake. The candle's flame should glow warmly, casting subtle light on his curious expression. The image is shot with a Nikon D850 camera, using an 85mm f/1.4 lens, ISO 400, and a shallow depth of field that highlights the child's face. Incorporate golden-hour sunlight streaming through a nearby window, illuminating specks of floating flour from baking and producing soft bokeh on the background's striped tablecloth.

The cake should display hand-piped buttercream frosting with the number '1' in vibrant blue, surrounded by scattered rainbow sprinkles. A wooden highchair tray in the foreground holds a half-eaten strawberry, adding organic detail. Include realistic touches such as a smudge of frosting on the boy's cheek, faint steam rising from the candle wick, and defocused birthday balloons in the background. Render the final image description with a 4K resolution feel, Fujifilm Pro 400H film simulation, and subtle grain structure to enhance authenticity.

# Steps
1. Describe the boy's appearance and expression with emphasis on softness and natural texture.
2. Detail the cake's design, frosting color, and sprinkles.
3. Specify lighting and photographic settings including camera, lens, ISO, depth of field, and sunlight effects.
4. Incorporate elements of the setting such as the wooden highchair tray with strawberry and floating flour particles.
5. Add subtle realistic details like the frosting smudge, candle steam, and background balloons.
6. Convey the overall atmosphere with warm lighting, shallow focus, and film simulation effects.

# Output Format
Provide a detailed, vivid descriptive paragraph suitable for guiding a visual artist or AI image generator to create a hyper-realistic image as specified. Use clear, sensory language and include all specified photographic and compositional details.
