Henry Mullins moved to Jersey in 1848, where he set up his studio in the Royal Square known as the Royal Saloon. His photography was represented in Societe Jersiase Photo-Archive, producing over 9000 portraits of islanders from 1852 to 1873.

His work was placed in various albums during the 19th century, showing individual faces and bodies of the first generation of islanders, in which he would place his clients in order of social hierachery. He would photograph Jersey Political elite, mercantile families, military officers and professional classes.

He used carte de visite to print his portraits, which was a small print called albumen print that was then sealed by egg whites, bind together with the photographic chemicals on the paper. These prints were affordable and common to many islanders, which were traded among friends and visitors, while albums and cards were also featured in Victorian parlours, during the 1860s. The portraits became very popular, which lead to the publication of portraits featuring famous people.

The four headshots Mullins captured are put together and presented in a Dimond Cameo which is a process where four separate portraits of the same subject are printed on a carte de visite.
