1973

In June 1973, Leutwiler used a professional 35 mm system to photograph his first sailboat race, the Marblehead, Massachusetts to Halifax, Nova Scotia race. He later stated the "quality was a disaster by my standards today", but as result of this race, Deadelus Photography was born (name changed to Leutwiler Photography in 1979). Leutwiler quickly realized that 35 mm would not produce sufficient images for professional enlargements, and soon made the permanent transition to Hasselblad cameras. He slowly began to find his market, selling his photographs primarily to sailboat owners, crew members, boat manufacturers, sailing magazines, and calendars published by magazines. In a 1987 interview with the St. Louis Post Dispatch, he compared his niche to "selling paper clips to General Motors".

1976

At the Miami-Nassua Race of the 1976 SORC, Leutwiler photographed Love Machine,^[1] which many sailors felt was the best action photograph of the period. It appeared as the cover of Yacht Racing Magazine in April 1976, and played a critical role in the building the recognition of the Leutwiler brand name. Wham Bam, Sunset, Tweety, Lonely Sea, and Condor were also published around this time and all became cornerstones of Leutwiler Photography.

1978

By 1978, about 1000 of Leutwiler's photographs had been published nationally in various companies' ads, brochures, and boat show displays. In the Fall of 1978, the first of many editions of the Shooting The Breeze newsletter was circulated to his ever growing customer list. The newsletter soon began to incorporate the elements of light hearted humor that would become a Leutwiler trademark.

1980–1981

In the Spring 1980 edition of Shooting The Breeze, Leutwiler announced "Here we are in the Spring of 1980 and I thought I would tell you about my first entirely Leutwiler calendar for 1981. We have selected 13 of my best photographs and are currently in production. The printing quality will be superb and I feel it will be the best sailing calendar for 1981." The 1981 calendar sold out, kicking off a highly successful decade-long run.

1982 – 1990

The 1980s were the peak years for Leutwiler Photography, as the annual calendar became a bigger staple of the sailboat racing world with each passing year, and his classic and new portraits continued to be a success. But after nearly twenty years of hard work and devotion, Leutwiler lost his passion and drive for sailboat photography and closed down the business in the 1990, selling off his negatives and camera equipment. He moved to Salt Lake City, Utah in the early 1990s and pursued a variety of other interests including real estate ventures. In 1993, he died in Salt Lake City.

In addition to photographing the event, in 1983 Tom paired up with television producer Stephen H. Schwartz to make "SORC:!983" a video documentary about the six races in the Southern Ocean Racing Conference. The film was sponsored by SEBAGO and was sold in the newly popular VHS and BETAMAX formats. The documentary was narrated by Gary Jobson.
