Was going to a Life Drawing Session today, and turned out like this.
本來要去畫人體素描,結果畫了張西雅圖市區街景.

Fun Project_My First Android App
My first hello apps, codes were copied from Android developers' site. There are not much resource online and had hard time running the apps and exporting to the phone. After one day, finally put on my phone! :)
我的第一個Android程式,Android的網路資源真的沒iPhone多,版本很多,又有不同解析度,花了一天總算把程式放到手機上了! :)

光源.光.光的遞減.物體受光.受光的遞減與畫的關係[一]
[圖一]
[圖二]
在繪畫上,為什麼線條這麼有效率,還有線條為什麼這麼快速的可以達到效果?
為何一條細線可以體現物體的立體感?
實際上畫本身並不會發光,某些畫作上卻讓人覺得發光的感覺.
光影遞減和物體受光的關係,在畫作上的轉化與呈現,這些都是特別有趣可以深入探討的.
光的遞減與距離的關係並不是線性遞減的,而是平方的遞減.
假設光源在右邊, 圖一中上圖表現的比較接近實際光源的遞減,而圖一底下是線性的遞減.
依照這明度分布:
一幅完整光影的畫,包含了發光體與影子,普遍來說,其中明度較高的50%的變化區域集中在10~25%的面積之中,這代表大多數的面積的明度都相對於整體都是呈現較接近的且都是明度較低的,而描繪高光就顯得特別的重要. 這說明著想在一幅畫中表現出光感,明度的分布方面,多數的面積以明度較低的色彩去表現,在小面積上集中使用明度高且變化較大的色彩. 在400年前, Georges de La Tour, 和Rambrandt Harmenszoon van Rijn就應用在畫作上,而且技巧之高明,就算現代仍是難以超越,但就理論上而言,這種類似的光影感覺是可以建構出來的,不過這只是單純光的遞減,立體物體受光角度在平面上畫作上的明度遞減更不是線性的.
已經將近凌晨6:00了,有機會再把這文章寫的完整些.

Daji and King Zhou of Shang in 1047 BC_妲己與殷紂
[Temporary remove the painting, put it back on until next version]
There is much Chinese folklore which includes songs, and tales, and it tells stories of historical, human nature, events, or love. Here is a story about Daji and King Zhou of Shang in 1047 BC. Daji was a favorite concuibine of King Zho of Shang. She is a classic example of how beauty causes the downfall of an empire/dynasty in Chinese culture. She is portrayed as an evil fox spirit in Chinese novel Fengshen Yanyi which is translated as The Investiture of the Gods or The Creation of the Gods, also known as Fengshen Bang.
妲己，殷紂之妃也。紂伐有蘇，有蘇女以妲己，美而辯，用心邪僻，夸比於禮，戚施於貌。紂好酒淫樂，不離妲己，其言是從，所譽者貴之，憎者誅之。
乃使師延作朝歌北鄙之音，北里之舞，靡靡之樂。造鹿臺為瓊室玉門，其大三里，高千尺，七年乃成。厚賦稅，以實鹿臺之財，盈鉅橋之粟，燎焚天下之財，罷苦萬民之力。故狗馬奇物，充牣宮室，以人食獸，廣沙丘苑臺，以酒為池，懸肉為林，男女裸相逐於其間。宮中九市，為長夜之飲。百姓怨望，諸侯有叛者。妲己以為罰輕誅薄，故威不立，乃重為刑辟，為熨斗，以火燒燃，使人舉之手爛，更為銅柱以膏塗之，加於炭火之上，使有罪緣之。紂與妲己，以為大樂，名曰炮烙之刑。
