Studio Activewear Fashion Portrait

Aspect ratio: 4:5
Scenario description:
Overall Scene: A high-resolution, unedited original photograph depicting a woman in a dynamic pose against a pure white seamless studio background. The lighting in the setting is even, using soft studio lighting. The entire image is clearly focused, with no background blur or depth of field effects; the subject and background show equally clear detail.
Main Body:
Character: A young woman with brown curly shoulder-length hair.
Posture: Sit on the floor with your right arm supporting yourself backward. Left leg bent, feet on the floor. Straighten your right leg and lift it upward. She looked straight into the camera, smiling.
Clothing: Gray short-sleeved jumpsuit with buttons on the front. Dark charcoal gray, with visible fabric texture. White mid-calf socks rolled above the ankle, with visible knit texture. Chunky sneakers, gray-white New Balance style dad sneakers with distinct soles and patchwork. The shoes are clearly focused on both feet (one on the floor, the other lifted).
Distinctive feature: a delicate small tattoo on the inner right forearm near the wrist.
Environment:
Floor: Clean, smooth white studio flooring.
Background: Seamless, pure white studio walls extending from the floor.
Technical Specifications:
Camera: Sony A7R IV full-frame mirrorless camera.
Lens: Sony FE 50mm f/1.8 lens.
Settings: aperture f/11 (for deep depth of field and overall scene sharpness), shutter speed 1/250 sec (for freezing pose), ISO 100 (for low noise).
Lighting: Two large softboxes (main and fill light) and a background reflector provide even, clean light with minimal and distinct shadows.
Focus: Sharply focus on the subject's face, extending to the feet and background.
Color profile: natural, unedited original colors.
Image quality: 4K resolution, HD photography, clean and uncompressed original file feel, high color fidelity, natural film grain (minimized at ISO 100).
Post-processing instructions: Do not use artificial background blur (blur) or excessive smoothing. The depth of field should be relatively wide, determined by the f/11 aperture setting. The textures of the bodysuits, socks, sneakers, skin, and hair should be highly detailed and clear. The white background should remain uniform and bright white, without blurring.
