1871 – Richard Leach Maddox (1816 – 1902) an English physician began experimenting and produced lightweight gelatin negative plates. Charles Harper Bennett (1840 – 1927) another English photographic pioneer went on to improve this process, hardening the emulsion and increasing the sensitivity. This increased sensitivity of 1/25 second paved the way for the snapshot. 1871年——理查德·利奇·馬多克斯(1816-1902),一位英國醫(yī)生開始試驗并生產(chǎn)輕質(zhì)明膠底片。查爾斯·哈珀·貝內(nèi)特(1840-1927),另一位英國攝影先驅(qū)繼續(xù)改進(jìn)這一工藝,使乳劑變硬,提高靈敏度。這增加了1/25秒的靈敏度,為快照鋪平了道路。 未經(jīng)授權(quán),不得轉(zhuǎn)載! |
