<Li> 1888 : The first model of the Kodak camera appeared . It took round pictures 6.4 cm ( 2.5 in ) in diameter , was of the fixed focus type , and carried a roll of film enough for 100 exposures . Its invention practically marked the advent of amateur photography , as before that time both apparatus and processes were too burdensome to classify photography as recreation . The roll film used in the first model of the Kodak camera had a paper base but was soon superseded by a film with a cellulose base , a practical transparent flexible film . The first films had to be loaded into the camera and unloaded in the dark room , but the film cartridge system with its protecting strip of opaque paper made it possible to load and unload the camera in ordinary light . The Kodak Developing Machine ( 1900 ) and its simplified successor , the Kodak Film Tank , provided the means for daylight development of film , making the dark room unnecessary for any of the operations of amateur photography . The earlier types of the Kodak cameras were of the box form and of fixed focus , and as various sizes were added , devices for focusing the lenses were incorporated . </Li>
