Precision process workers do detailed tasks, such as airbrushing and spotting, which can contribute to eye fatigue. Some photographic process workers are exposed continuously to the chemicals and fumes associated with developing and printing. These workers must wear rubber gloves and aprons and take precautions against these hazards. Many photo laboratory employees work a 40-hour week, including weekends, and may work overtime during peak seasons. About 1 out of 7 worked for portrait studios and commercial laboratories that specialize in processing the work of professional photographers for advertising and other industries.
Employment fluctuates somewhat over the course of the year.
Typically, employment peaks during school graduation and summer vacation periods, and again during the winter holiday season. New employees gradually learn to use the machines and chemicals that develop and print film. Employers prefer applicants who are high school graduates or those who have some experience in the field. Such courses are available through high schools, vocational-technical institutes, private trade schools, and colleges and universities. Some workers attend periodic training seminars to maintain a high level of skill.
