The first photographs on Taiwan, it is generally considered, must have been taken during the period shortly after the signing of the Treaty of Tientsin in 1858, which made Taiwan a foreign trading port and opened up a flood of western missionaries and traders.
西元一八五八年，台灣在天津條約中開放為通商口岸，西方商人、傳教士自此大量湧入。一般認為，台灣的第一張照片，或許出現在這段時間。
