這週畫室課堂教學練習到鼻子靜物組，花了點時間整理鼻子畫法與隱藏結構，
如果畫友喜歡畫人物或是想知道怎麼畫鼻子跟認識結構知識可以一起看下去喔!
為什麼要學鼻子結構？
- 鼻子是臉部立體感最突出的部位之一
- 提升鼻子與周圍臉部的結構合理搭配
- 透過理解結構，可以避免「貼上去的鼻子」，而是讓它自然長在臉上
鼻子的外觀觀察
鼻子的三大區塊：
鼻樑結構
- 上段：鼻骨（硬，固定）
- 中段：上外側鼻軟骨（略展寬，過渡）
- 下段：中隔軟骨（支撐鼻尖的主樑）
鼻樑功能
- 決定鼻子挺度、寬窄胖瘦感
- 連結額頭與鼻尖的主要通道
畫鼻樑時建議：
正面：鼻樑是「亮帶」，由內眼角間延伸到鼻尖
側面：從額頭到鼻尖有連續坡度，中段略有「骨 → 軟骨」的小角度過渡
3/4：鼻樑常形成一個亮面，兩側轉入暗面
鼻頭結構
- 主要由 大翼軟骨的內側腳構成+ 脂肪墊
- 鼻小柱 在鼻孔之間，連接中隔軟骨
- 外覆皮膚層多為厚實、含油脂的球形表皮
鼻頭功能
- 鼻尖是鼻子最柔軟、最有彈性的部分
- 鼻小柱決定鼻孔形狀與立體感
鼻頭畫法觀察建議
- 呈橢圓形或球狀，大小因人而異
- 是鼻子最突出的前端高點
- 鼻尖通常會形成明亮的高光圓點
- 鼻小柱：形成鼻孔之間的厚度，不可忽略
- 仰視：鼻尖呈圓弧，鼻小柱明顯，鼻孔呈三角
鼻翼與鼻孔
- 由 大翼軟骨外側腳 + 小翼軟骨 + 纖維脂肪組織組成
- 外側最柔軟，支撐來自脂肪與纖維組織
鼻翼功能
- 保持鼻孔開口
- 在呼吸/表情時可張開或收縮
鼻翼畫法與觀察
- 正面：鼻翼形態影響鼻子寬度
- 側面：鼻翼外緣有厚度，與臉頰過渡不是銳角，而是柔軟漸變轉折
- 仰視：鼻翼形成鼻孔外框，左右對稱性很重要
鼻子是「由平面到圓形」的過渡，簡單理解成:（鼻樑長方 → 鼻頭球形 → 鼻翼弧線）
不同角度的基本形狀（正面像是三角形、側面突出的梯形、仰視倒心形）
骨骼基礎（硬支架）
- 上方硬骨：鼻骨 → 與前額骨相接
- 下方軟骨：沒有骨頭，靠軟骨組織與皮膚支撐
- 功能：支撐臉部中央、決定鼻樑高度
軟骨結構（塑造外形特徵的推手）
- 上外側鼻軟骨：承接鼻骨，延伸鼻樑
- 大翼軟骨：形成鼻尖與鼻翼的主要形狀
- 大翼軟骨（關鍵）：形成鼻尖與鼻翼弧線。
- 中腳 → 支撐鼻尖
- 外腳 → 決定鼻翼弧度與鼻孔外框
- 小翼軟骨：在鼻翼旁邊，影響鼻孔形狀
- 皮膚與脂肪厚度 → 決定鼻尖是「挺」還是「鈍」
●First, let's break the nose down into basic components (parts):
You can think of the nose as being composed of geometric shapes, such as a triangular prism (bridge of the nose + nostrils) and a sphere (tip of the nose and nostrils). Before you start drawing, understanding these basic shapes can help you grasp the overall structure of the nose. For details, please see the image in the top right corner.

●Perspective and Proportion:
Ensure the proportions of each part are accurate, especially maintaining the perspective correctly from different angles. Refer to the bottom left and bottom right corners to observe the changes in perspective of the nose from different angles.
●Light and Shadow:
To create a three-dimensional effect for the nose, observe the direction of the light source and mark the shadow areas according to the shape's contours.
不同角度鼻子處理參考
以下是我在寫生畫鼻子處理作法，理解前段文章提到的知識點後
我們從解構轉折點的位置下手，做出明暗變化，觀察參考圖可以發現在鼻樑交界面上處理比較模糊( 還要考量打光的遠近有關連)
鼻子相較於眼睛、嘴巴裂縫，它的明暗過度上比較平緩，因此我們在處理上要注意彼此間的強弱差異
