Deliberately using incorrect ‘camera’ setting can sometimes give you a more pleasing or more interesting image than one taken with the correct camera settings. I think the term ‘accidentally on purpose’ nicely describes this form of technique that is somewhere in the grey area between creative camera use and user error.
Here is one example of using white balance creatively. In this image, exhibited in the bog entry entitled A Wander onto the Moor, I have set the white balance to tungsten, producing a warm result that would be similar to a ‘correctly’ taken image with a blue sky overhead reflecting in the ice. The simplicity of just the ice, the faintest of blue/magenta tones with the shadows really makes this image. The correctly taken image with the white balance set to auto is cold and lifeless.
