Hinkson is a landscape painter interested in the colours, forms and shapes created by tropical light. Although comparisons often lead to late 19th century French paintings, looking at early 20th century American landscape and figurative painting may also offer insight as to his inspiration. Hinkson has also been compared to Winslow Homer, Cezanne as well as Michel-Jean Cazabon, who recorded Trinidad's landscape in the 19th century.
In 1960, Hinkson exhibited his work in 'Five Young Artists.' The exhibition included the work of Pat Bishop, Isaiah James Boodhoo, and Peter Minshall. In 1970, Hinkson returned to Trinidad and began painting outdoors - 'en plein air' - using watercolour, and travelling and exhibiting throughout the Caribbean. Considered one of the region’s leading watercolourists, Hinkson also produced many series of drawings recording the country’s disappearing architectural heritage. He also began to use the medium of oil in the mid-1990s as well as making excursions into sculpture.
The artist holds a BFA and a Diploma in Education.
