【比較用】商品写真：陶器のコーヒーマグ

An editorial product photograph of a matte off-white ceramic coffee mug, half-filled with freshly brewed dark coffee, resting slightly left of center on a weathered oak tabletop against a deep teal backdrop. The image is captured with a Fujifilm GFX 100 II medium-format camera and an 80mm lens at f/2.8, framed in a vertical 4:5 composition. Soft morning window light falls from the upper right at a gentle 45 degree angle, creating a quiet chiaroscuro across the scene, while a delicate golden rim light traces the left edge of the mug. A faint curl of steam rises from the dark coffee surface, catching the light mid-air. The color grading emphasizes warm amber highlights on the mug, the rich near-black tones of the coffee, and the muted teal shadows of the background, evoking the restrained editorial stillness of a Kinfolk magazine photograph.
