He improved the gelatin silver process developed by Richard Leach Maddox, first in 1873 by a method of hardening the emulsion, making it more resistant to friction, and later in 1878 Bennett discovered that by prolonged heating the sensitivity of the emulsion could be greatly increased.[1] This increased sensitivity resulting enabled shooting at 1/25 second, paving the way for the snapshot.
