High-Key Lighting
Bright, low-contrast tones keep information clear and can suggest a relaxed or deliberately sterile setting.
Prompt
Use High-Key Lighting: raise broad soft illumination throughout the existing corridor and on the character, with strong gentle fill so shadows are pale and low contrast. Preserve visible texture in the white coat and pale walls; do not clip highlights or turn black clothing white. Keep subtle contact shadows and three-dimensional folds. No new light fixtures.

Effect comparison
In the baseline image, the corridor corners and Biwa's lower body contain deeper shadows. High-key lighting brightens the walls, floor and figure together, softening the shadows while preserving texture in the white coat and pale walls. The bright, low-contrast treatment makes the whole setting easy to read, so the figure is no longer surrounded by dark corners.
