    I’m really a big fan of stable diffusion. In the past two days, during my free time after work, I tried ChatGPT (helps me to optimize my positive and negative prompts), stable diffusion (diffusion model. It can help me to create images by prompts), ControlNet canny (use designed lines to control the image output), Real-ESRGAN (convert image from low quality 512*512 to high quality 2048*2048), LoRA (highly efficient algorithm to train a model with limited training data), LaMa (remove some parts from an image that I don’t want), LDM(as left. Quality is a bit higher than LaMa, but speed is much slower than LaMa), and rembg (remove background for some elements that you want to add to your image) models to visualize my ideas. Finally, I got this piece “Human”. It exactly fits the concepts that I had imagined two days ago. Even several months ago, I can’t imagine that I am able to use all these models freely and without limitations, just on my laptop.

  • Rembrandt(倫勃朗/林布蘭)與未來的一眼對視

    波士頓美術館 2022年荷蘭藝術展馆(CNA, Dutch and Flemish Art)中,Rembrandt一幅畫約1628年的小尺寸油畫Artist in His Studio非常讓人疑惑。

    這幅畫作中,令人預期待的Rembrandt lighting漫不經心地照射著背景人物。人物被虛化,臉上毫無細節,蠟黃臉色,呆板的眼神,人物姿態平平無奇,彷彿是個劣質娃娃。這樣拙劣的表現形式不禁讓館員也開始用隱喻來為這幅畫救場:

    A young artist stands in a nearly empty studio, brushes in hand. Rather than showing the artist in the act of creation, Rembrandt focuses on the daunting expectations of the surface to be painted. This little picture asserts that making art is an intellectual act as much as a technical one, a product of the mind as well as the hand. The painter here is conscious of the task ahead – think about how the looming easel blocks his way to the door – and maybe even of his place within the Netherlandish artistic tradition.

    館員用這幅畫中心畫架的隱喻來想像這幅小作品的創作意圖。

    畫作中心的畫架確實值得稱道,它承載了畫面中的有趣的光影和大量細節。從整幅畫的視覺引導上看,由門和兩面牆構築的三個相互垂直的面非常有趣,Rembrandt 在其他畫作中也嘗試過如此垂直空間的探索。在精彩的相互垂直的三個面構成的空間中,觀者視線很容易停留在畫面中唯一人物上,無論是因為觀者對Rembrandt lighting 的期待,或是藍色的衣服這樣獨特的顏色。接下來,畫面中人物的雙目把視覺引導線導入畫架。更有趣的是,畫架的左邊(觀者角度的左邊)的一條高光白線把視線導向地面?!

    這段視覺引導確實沒有被誤解,因為地面上顯然有更多的光照和紋理細節。視覺引導的期待得到來自畫面細節和光影的回應。可 Rembrandt 盡力描繪地板上的紋理?這是為什麼呢。

    讓我們把視線擴大回整幅畫面,也許慢慢你會發現這幅畫有種奇怪的不和諧和趣味。透視和光影都是對的,可總覺得奇怪。彷彿畫架是一個縮比玩具模型,人物像是一個模型娃娃。如果熟悉攝影、攝像和鏡頭,也許你已經想到 tilt–shift photography(移軸攝影)。對大多數讀者來說,可能最著名的 tilt–shift photography 例子是 Sherlock 的片頭 https://www.youtube.com/watch?v=9ZABO1mNuSc. Tilt-shift 需要一個非常狹窄的景深(depth of field)

    在Artist in His Studio這幅畫中,從地面和人物臉龐、身上的光照來看,剛好有一束光打在人物與畫架中間。

    任何在這束光之內的細節描繪都會讓這幅畫帶給觀者「微縮模型」式的 tilt-shift 趣味。我們會驚奇地發現,確實,Rembrandt 接下來把大多數細節和光照都給予了這塊有魔力的空間。基於「單點透視」(one point perspective)的原則,顯然 Rembrandt還不太敢突破透視傳統,更多探索這一片狹長的景深區域(给予画面中一个虚拟狭长长方体空间内的物品更多细节)。但明確的光照和有限的細節已經足以讓這幅畫擁有足夠多的tilt-shift 趣味。

    Tilt-shift 所基於的現代摄影鏡頭和光線技术基礎要到二十世纪六十年代才被建立。Rembrandt 在這幅十七世紀的小尺寸作品Artist in His Studio中意外的發現了 tilt-shift無法言說的趣味,可這終究只是一次和未來的短暫對視。假如Rembrandt對這幅小作品再添加一些細節,進而發現這個神奇的窄景深空間的完整邊界,也許藝術史的透視技法發展歷程會被改寫。
