Part 1. A selection of images using lines to create a sense of depth.
All images captured with a Canon G1-X, at the wide end of the zoom range.
Classic use of a single vanishing point (top of the blue panel and the far-centre of the road) with diagonal lines leading to it from all of the horizontals in the scene. Both kerbs, the yellow lines, building bases and various string courses. There is also an implied line formed by the ground floor arches of the building at near-right.
The same device but with a vertical context. The vanishing point is on the lowest floor, below the camera position and all the verticals converge there. The staircase handrails and strings also lead us downward.
It is interesting that converging verticals are more acceptable when looking downward than upward. We get a sense of a high viewpoint and possibly a touch of vertigo. The vanishing point is well below the bottom of the image, so there is a risk of dragging the eye out of the image at the bottom. In this case, the handrail and the seated group act as eye-stoppers.
This image combines all of the techniques of the earlier examples. There is a horizontal vanishing point near the top-centre and the converging verticals of the ground-floor columns give us a sense of height. The staircase balustrade leads us from the camera position to the centre of the image. Fortunately, the steps and handrail are near-horizontal at the bottom-right so avoid dragging the eye strongly out of the image.
A similar effect, but using a curved line.
This is an artificial example (a detail of the pedestal of Paul Day’s statue at St Pancras station), a low-relief bronze casting which uses line to give an illusion of depth.
Part 2. A set of images using line to flatten the pictorial space.
All images captured with a Canon G1-X, in the centre or long end of the zoom range.
In this case, the subject is effectively flat and the flatness is emphasised by arranging all relevant lines parallel to the edges of the frame.
The subject in this image is deeper, but presents as a series of parallel planes. By approaching it square-on and arranging the major lines parallel with the edges of the frame I have tried to eliminate the clues about separation of the planes, thus flattening the space. Unfortunately, the shelves inside the door to the left lead to a vanishing point and compromise the illusion slightly.
A similar technique, suppressing clues about the separation of planes.
Shooting vertically with a long-focus lens and arranging the tile pattern parallel with the edges of the frame we lose the impression of depth. The converging verticals of the balustrade are reasonably minor.
