Benkichi Ohno, a Karakuri Master, invented the negative exposure camera

In 1849 (Kaei 2), Benkichi Ohno, a Karakuri Master (an expert in mechanical devices,) invented a practical photographic method that allowed printing without reversing right and left. This technique was unknown in Europe at that time. Two years later in 1851, Frederic Scott Archer, one of the fathers of practical photography, invented glass negative photography. Read More »
