黑白照片为什么有很强的艺术感？

黑白照片之所以具有强烈艺术感，部分原因在于它们去除色彩的干扰，使得光影、纹理和构图成为视觉的核心。这种简化突出了照片的形式美，增强了图像的情感强度和视觉冲击力。黑白照片还能传达一种时间感，唤起人们对于过去的回忆和怀旧情绪。此外，由于它们在早期摄影中广泛使用，黑白照片往往与历史、文化 heritage 和经典美学联系在一起，增加了其艺术价值。

清明节的来历是什么？

-speaking context, the Qingming Festival, also known as Tomb Sweeping Day, originated as a day to honor ancestors and clean their graves. It dates back to the Zhou Dynasty (1046–256 BC), but it became a formal observance during the Tang Dynasty (618–907 AD) when Emperor Xuanzong declared it a public holiday. On this day, people visit grave sites to pay respects, clean the tombs, and offer food and flower offerings.

The Qingming Festival also marks the beginning of spring, and it is a time when people traditionally go outdoors to enjoy the natural beauty of the season.

清明节，又称为踏青节或扫墓节，是中国传统的重要节日之一，主要用来纪念祖先和清扫墓地。清明节的起源可以追溯到周朝（公元前1046年—公元前256年），但到唐朝（618—907年）时，唐玄宗将其定为官方节日。这一天，人们会前往祖先墓地，进行墓地清理、献上食物和鲜花等传统仪式，以表达对先人的怀念和尊敬。清明节不仅是祭祖的日子，也标志着春季的开始，人们常常借此机会外出踏青，享受春天的自然美景。清明节还体现了中国传统文化中对孝道的重视。
