Photography is not only about what you see, but also about what you feel. Sinden's images elicit mood and atmosphere in a photographic style which she describes as a “re-creation of reality ... embodying the dreamlike quality of years gone past. Sometimes it lies in the grit of the urban streets, or the quiet pensive moments of thought and emotion.”
In 2001, Sinden Collier became the first Black female photographer to be signed to Getty Images. In 2003 and 2004, her images were also featured as part of the Nordstrom’s National Juried Show of African American Photographers. During The Month of Photography Los Angeles 2018, Sinden participated in "Doyennes of Photography in LA" - a group show highlighting a diversity of women photographers working across different genres.
