罐子內部也是同理使用三色疊加來上色，並依照罐子的紋理上色。
最後用衛生紙於罐子底部擦拭，讓顏色擴散至罐底作為反射
並使用橡皮擦擦拭罐子部分顏色，來反映光線的反射
Types of Light and Their Effects on Photography and Painting
光源的種類有自然光、人造光、混合光，其中光線還有分為硬光和軟光，但攝影和繪畫中要注意的是光線的方向：
Light sources can be categorized into natural light, artificial light, and mixed light. Additionally, light can be classified as hard or soft. In photography and painting, the direction of light plays a crucial role:
逆光：光源位於拍攝主體的背後，可以產生輪廓光，突出主體，可以營造出神秘的氛圍，將人物置於逆光下，頭髮和輪廓線會被光線勾勒出來，形成美麗的輪廓光，營造出夢幻的氛圍。
Backlight: With the light source positioned behind the subject, backlight creates a rim light that outlines the subject, producing a mysterious atmosphere. Placing a person in backlight highlights the hair and contours, forming a beautiful rim light and a dreamlike ambiance.
側光：光源位於拍攝主體的側面，可以增加物體的立體感和質感，將靜物置於側光下，可以清晰地看到物體的立體感和質感，適合拍攝產品或食物。
Sidelight: When the light source is positioned to the side of the subject, it enhances the object's three-dimensional form and texture. Sidelighting on still life subjects reveals their volume and texture, making it ideal for product or food photography.
順光：光源位於拍攝主體的正面，光線柔和，適合拍攝人像，但容易產生平面的效果。
Frontlight: With the light source directly in front of the subject, the light is soft and suitable for portraits. However, it can create a flat appearance.
頂光：光源位於拍攝主體的正上方，可以產生強烈的陰影，適合表現物體的形狀。
Top light: When the light source is directly above the subject, it casts strong shadows, emphasizing the subject's shape.
底光：光源位於拍攝主體的正下方，可以產生神秘、詭異的氛圍。
Bottom light: With the light source positioned below the subject, it creates a mysterious and eerie atmosphere.
光線會影響物體的色彩，不同的光源會產生不同的色彩效果；光線的明暗對比來塑造空間感，讓畫面更有深度；更可以營造不同的氛圍，傳達不同的情感。
Light influences the color of objects, with different light sources producing varying color effects. The contrast between light and shadow creates a sense of space and depth within an image. Moreover, light can be used to establish different moods and convey various emotions.
