Cronjager began working in film in the late 1950s. Working as an assistant cameraman or 2nd assistant cameraman, he began on the 1957 comedy,
Oh, Men! Oh, Women!. He also worked on the notable films,
South Pacific (1958),
The Hustler (1961), and
Rio Conchos (1964). Beginning with taking over the photography on
Peyton Place in 1967, he would work consistently in television through his retirement in 1988. Following
Peyton Place, he would move to ''
Bracken's World'' in 1969, staying with that series until it ended in 1970. During the 1970s and 1980s, Cronjager was the original director of photography on the television series
Columbo and
Hart to Hart. His only other, and final, work on the big screen was on another low budget picture, 1976's
Vigilante Force. During the 1970s, he worked on several notable television series. He took over the camera helm for the second series of the western,
Alias Smith and Jones in 1971, and was frequent DP on
Columbo. In 1980, Cronjager was selected as the director of photography for the new police drama,
Hill Street Blues. For the initial episode, titled "Hill Street Station", Cronjager chose to shoot approximately 90% of the show utilizing hand-held cameras. His work garnered him a
Primetime Emmy, for Outstanding Cinematography in a Series. Even though Cronjager had no involvement in the original
Cannon television series from 1971 to 1976, when the series was resurrected in 1980 as a television film, the film's director, Corey Allen, selected Cronjager to shoot the picture. The TV film was titled
The Return of Frank Cannon, and Allen was impressed with Cronjager's work on
Hill Street Blues. For one scene in the film, it was necessary to light a six-acre set for a nighttime shoot. It took Cronjager and his crew seven and a half hours setting up the scene's lighting, which took up 6000 feet of cable and used about 3,000 amps. In the final product, the scene took up approximately 5 seconds of air time. Cronjager's last project was the 1988 television film,
Broken Angel (tv film), starring
William Shatner and
Susan Blakely.
