Horizontal and vertical references can anchor a photograph even when they are not perfectly straight. In a portfolio attributed to Joerg Dauerer, look for lines that divide the frame: an edge, a roof, a shoreline or a change in tone. Note how much space lies on either side and where other shapes interrupt the division. Begin with visible structure rather than assumptions about the subject.
Compare a frame with a strong dividing line to one without it. Does your eye settle more quickly in one, and is that helpful to the picture? The absence of an obvious anchor can be as significant as its presence. Record the effect in your own words, keeping any technical correction you might prefer separate from the visual choices the photograph actually presents.
