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·马多克斯(1816-1902),一位英国医生开始试验并生产轻质明胶底片。查尔斯·哈珀·贝内特(1840-1927),另一位英国摄影先驱继续改进这一工艺,使乳剂变硬,提高灵敏度。这增加了1/25秒的灵敏度,为快照铺平了道路。 未经授权,不得转载! |
