English: Richard Leach Maddox (4 August 1816 – 11 May 1902) was an English photographer and physician who invented lightweight gelatin negative plates for photography in 1871.
Čeština: Richard Leach Maddox (4. srpna 1816 - 11. května 1902) byl anglicky fotograf a fyzik, který vynalezl lehké suché želatinové desky s bromostříbrné pro fotografický průmysl v roce 1871.
Mokrý kolodiový proces vynalezl v roce 1851 Frederick Scott Archer. Tyto obrázky vyžadovaly pouze 2 až 3 sekundy světelné expozice. Ale desky musely být zcitlivené na určitý čas expozice a zpracovány ihned ještě mokré. |
