Starting with a photograph: Saatchi artists at the Michael Hoppen gallery

Blue Lake Revisited by Robin Cracknell. Combining photography with cinematography, the artist scratched and treated the image with unpredictable chemicals, to convey the disappointments of childhood and adult regret Photograph: Michael Hoppen Contemporary and Saatchi Online

Chair (2008) by Hannah Dakin. Her approach plays with the idea of the photograph as object, printing on different textures which are then layered, often with a film of wax in between Photograph: Michael Hoppen Contemporary and Saatchi Online

Giovanni (2009) by Maurizio Anzeri. The artist works with found photographs, embellishing them with coloured threads to create three-dimensional, almost sculptural, images Photograph: Michael Hoppen Contemporary and Saatchi Online

Light I (2009) by Gabriele Beveridge. Playing with the process of image-making, the artist cuts up transparencies and photographs and reprints them as new Polaroids Photograph: Michael Hoppen Contemporary and Saatchi Online

The Composites (2009) by DY Kim. The artist takes photographs from different angles and then layers the negatives on top of each other to create a new image, capturing the subject in 360 degrees Photograph: Michael Hoppen Contemporary and Saatchi Online

Unknown Soldier (2009) by David Birkin. This photograph is part of a wider body of work by the artist that focuses on a single soldier, titled 'Confessions of an Unknown Soldier' Photograph: Michael Hoppen Contemporary and Saatchi Online
