With many years 'experience photographing butterflies in the wild, Tsai has developed swiftness, aggressiveness, and accuracy in his work. He has high expectations of himself: his photos must clearly depict the movements and habits of the butterflies, their motions must be natural and fluid, their colors need to be accurate and sharp, and the photos must be well composed.
長年在野外拍蝶，蔡百峻練就一身快、穩、準的功夫，還嚴格要求自己：照片必須將蝶瞬間的行為交代清楚、動作必須自然流暢、色彩應準確銳利，且需具備圖鑑比對功能。
