A product-style editorial photograph of a handmade stoneware mug filled with black coffee, set on a windowsill at dawn. The mug has a matte sage-green glaze with subtle finger-throw marks visible on its surface. Thin wisps of steam rise and catch the first light of sunrise filtering through frosted glass, creating luminous backlit halos around each tendril. Shot at 105mm macro, f/2.2. Shallow depth of field keeps the mug's rim and steam sharply detailed while the interior blurs to a dark, reflective pool. No label or text. Color palette: sage green, deep espresso brown, pale gold, morning mist white. Mood: meditative, slow, contemplative — the first quiet moment of the day.
