As a pictorialist, Eickemeyer believed photographs were works of art.
 However, he believed in producing straightforward images and using natural elements to produce artistic effects instead of using photographic techniques (such as soft focus) to imitate traditional art.
 He was described by photography critic Sidney Allen as the "most versatile" pictorialist of his time, and excelled in both landscapes and portraits.

In 1893, Eickemeyer's photographs, Lily Gatherer and As She Comes Down the Stairs (for which his wife, Isabelle, posed) won silver medals at the Joint Annual Exhibition in Philadelphia, and the latter won the gold medal at the Hamburg International Exhibition.
 In 1894, Eickemeyer won sixteen medals in ten international exhibitions, including the Royal Photographic Society's Albert Medal for his Sweet Home.
 The following year, he won the Viceroy Gold Medal at the International Exhibition in Calcutta for his photograph, Kitten's Breakfast.

Photographer Roland Rood described Eickemeyer's portraiture photographs of women as "unexcelled, frequently unequaled."
 His 1901 shoot of New York model Evelyn Nesbit is arguably his best-known portrait work, and included a shot of Nesbit clad in a kimono and curled up on a bear-skin rug.
 Other well-known women photographed by Eickemeyer include opera singer Mary Garden and actress Lillian Russell.

Eickemeyer published three photographic books: Down South (1900), The Old Farm (1901), and Winter (1903).
 Down South documents the lives of African American sharecroppers on an Alabama plantation, using photographs taken by Eickemeyer during various trips to Alabama during the 1890s.
 The Old Farm is a collection of rural images, and Winter is a collection of artistic winter images accompanied by quotes from famous authors.
 Eickemeyer also provided photographic illustration for books by several other authors, including In and Out of the Nursery (1900), a collection of poems written by his sister, Eva.
