In terms of the development of special techniques, double and triple exposures were the most favored tricks of that age. Having one person appear in the same picture two or three times, with different costume, dramatically arranged, satisfied the desire of the average person to "play several roles." "Oil portraits" and "watercolor portraits" were also in fashion in this period.
在特殊技巧的開發上，雙重曝光、三重曝光，正是當時流行的特殊技巧，一個人二、三種打扮，利用曝光出現在同一張相片中，戲劇性的安排，滿足了一般人「一人雙影」的心理。
