epididymis

I copied a reproduction of the silverpoint using a homemade epidiascope based on a small circular concave mirror and direct solar illumination , and when i deliberately “ bumped ” my own epidiascope , i found such a mismatch to be very conspicuous 我用小型的圓凹透鏡與陽光組成的自制幻燈機,從銀尖筆畫復制了一張畫,而當我蓄意碰撞自己的設備后,我發現位移結果是非常醒目的。

Hockney and falco explain this shift as follows : van eyck traced part of the image projected in an epidiascope , then accidentally bumped the silverpoint , the oil or the mirror , and finally traced the remaining , now shifted , image 霍克尼與法柯對此位移的解釋如下:范艾克用幻燈機描了部份的影像后,不小心碰到銀尖筆、油畫、或者鏡子,然后繼續描完剩下已經位移的影像。
