On Images and AI

The Lines Humans Draw The lines in a drawing made by human hands carry momentum, languor, suppleness, hesitation, sensuality. Some of these qualities are consciously sought; others emerge unconsciously. In a picture drawn by a person, such qualities are naturally adjusted and woven in. The word “sensuality” does not mean only sex appeal. We often speak of “mature allure,” but this is a complex thing, and eroticism is no simple matter either — because sex appeal has no pattern. ...

Unlike today, animation at that time was drawn on paper, traced onto cels, and painted by hand. Normally, cels were discarded after a production was completed.

Welcome to My Blog

My name is Sadao Tsukioka. After graduating from a high school with an architecture program, I entered this world as an assistant to the legendary Osamu Tezuka. In 1959, when Tezuka participated in Toei Animation’s feature film Journey to the West, I was dispatched alongside Shotaro Ishinomori as Tezuka’s stand-ins — that was my start as an animator.

I was right at the heart of the birth of Japanese television animation. ...
