Curves

Exercise - 4 photographs


As with the previous exercise on diagonals, curves can be used within an image to add direction and a sense of movement. Diagonals move through the frame from point to point and like straight lines are relatively easy to create by altering your viewpoint. A diagonal line dissects an image. It is a strong, hard graphical element within the frame that purposely leads the eye directly through the scene. 


Curves on the other hand, although also adding a sense of movement and direction, can be weaved together to create a change in direction and encourage the eye to pause as it travels through the picture or in a certain direction. Curves are difficult to produce by altering viewpoint alone. Most will be "real" although not necessarily an object. They can be created by changes in light and shade e.g. in a landscape. Curves are softer, smooth and flow through an image. 


Image 1
Aperture Priority. ISO 200, 1/15 sec at f/11.
This image of an old back wynd in Edinburgh Old Town shows a strong curve from the bottom left of the image to the top right. In this respect it also acts as a diagonal which I hadn't realised until now but feels softer and has a slower pace through the image than a diagonal would have. 

Image 2
Aperture Priority. ISO 800, 1/13sec at f/16.
Technically this image is not very well executed as it is poorly focused and over/under exposed in places but it demonstrates a curve well. As your eye travels along the curve you notice first the stained glass windows then travel up to the circular ceiling.

Image 3
1/320 sec, ISO 400 at f/14.
These curves have been formed by the sea eroding away the layers of a rock.

Image 4
Aperure Priority. ISO 400, 0.6 sec at f/11.
In this final image multiple curves create a far greater sense of movement. In all four images above the curves have been a strong visual element in the image and have been obvious to the viewer. I need to remember that curves can also be implied in an image in the same way as multiple points can become straight lines or other shapes and for future reference try to create images which still meet the brief but are less graphic in style.

  1. Lovely set of images Nicola. I was only thinking the other day that you'd gone very quiet!
