Out of Focus
Ouch!
The focussed subject can only be recognised in a blurry, indistinct way.
Background
Blurring in photos can have different causes: Movement of camera and / or subject, adjustment of distance to deliberate blur. But also due to fog, reflection or special filters in digital image processing.
The renunciation of reference points emphasised by image sharpness enables the viewer to set his or her own references. Forms and structures of a world beyond the obvious and expected become visible.
