Ernst's work consists of extensive portrait series on socially engaged and socially difficult subjects. With these portrait series he pays attention to important topics such as diversity, inclusiveness, racism, discrimination and exclusion. Topics he feels close to being a gay man himself.
In these projects, the "underdog" is the star. Their strength is a source of inspiration, their story needs to be told.
These projects often consist of extensive multimedia photo/portrait series that are exhibited in exhibitions that travel throughout the Netherlands (and internationally) in (mainly) public space.
His work has been showcased at photo-festivals, museums, art-fairs and in public spaces in The Netherlands and abroad. With his work Ernst has won several awards including a Silver Camera Award, twice. His series 'SOLD' - portraits of victims of human trafficking - won 1st prize in the 2020 LensCulture Portrait Awards and was acquired by the International Slavery Museum in Liverpool (UK).
