ライティング比較グリッド

Produce one image holding a three-by-three portrait grid on a flat dark grey ground, using the subject described in the request or an uploaded reference. Keep identity, hairstyle, outfit, camera angle, framing, and pose identical across all nine cells so only illumination changes. Print a clean sans-serif number and setup name beneath each cell. Top row: loop lighting with a three-quarter key and compact cheekward nose shadow; hard frontal flash with flat shadows; split lighting dividing the face into bright and dark halves. Middle row: butterfly lighting whose elevated centered key casts a neat mark below the nostrils; a venetian-blind gobo striping face, clothing, and backdrop; under-lighting with inverted moody shadows. Bottom row: warm golden-hour side light; a narrow spotlight with deep chiaroscuro and crushed blacks; neutral rim light outlining hair and shoulders against black without front fill. Render every cell as a believable studio photograph with accurate falloff, contrast, and skin tone. No watermark, logo, or extra text. User request: a woman with short curly hair in a black turtleneck, head-and-shoulders framing
