Aged leather: three years later

Two states of the same leather armchair juxtaposed: on the left, it is brand new, with a uniform leather surface, consistent color, and sharp edges; on the right, it is the same chair after three years of use, with the front edge of the armrest and the center of the seat worn to a brighter, darker shade, fine natural creases appearing at the joints, and the color transitioning from a uniform brown to varying shades, making the overall appearance even better. The leather is vegetable-tanned full-grain, without coating, so it changes with use. Both chairs are at the exact same angle and lighting, only their condition differs. Soft side window light.
Avoid: Inconsistent angles or lighting between the two chairs, the old chair depicted as damaged or dirty, using coated synthetic leather, creases drawn as regular patterns.

同一張皮革扶手椅的兩種狀態並置:左邊是全新的,皮面均勻、顏色一致、稜角挺立;右邊是使用三年後的同一張,扶手前緣與座面中央被磨出較亮的深色,關節處出現細密的自然摺痕,顏色從均勻的褐轉為深淺不一,整體反而更好看。皮革是植鞣的全粒面,沒有塗層,所以會隨使用變化。兩張的角度與光線完全相同,只有狀態不同。柔和的側窗光。避免:兩張的角度或光線不一致、舊的那張畫成破損骯髒、使用有塗層的合成皮、摺痕畫成規則的紋路。
