20 November 2016. How time flies. On April 20th this year I found a photograph in our local newspaper, which I knew I would like to try for this exercise. It has neither trees in the foreground nor hills in the background as set out in the study guide, but the subject – strips made by tractor mowing the grass – and composition are so beautiful that I want to take the risk and try it nevertheless (Fig. 1).

Regarding the physics behind the phenomenon, which is well-known mostly from football fields, I found a (German language) explanation (Dewald, 2012). Countless artists noticed and made extensive use of the beauty of this effect. David Hockney (*1937, UK) used it in his series of Yorkshire landscape paintings, e.g. in “Garrowby Hill” painted in 1998 (Hockney, n.d.(a)) or “Going up Garrowby Hill” from 2000 (Pinterest, n.d.), both shown below as printouts from the internet (Fig. 1). It has also inspired more abstract painters such as Latvian artist Raimonds Staprans (*1926) (Fig. 2) and even quiltmakers, e.g. “Sunset Desert” by Gloria Loughman (*?, Canada) (Loughman, n.d.).


26 November 2016. After having had another look at my photo, I knew that I would want it changed somehow, because after the excursion to Hockney’s paintings it suddenly felt boring, and the pattern transferred to another, wider, undulating landscape. I went to look for suitable photos and decided to superimpose the former on the latter, changing both colours and composition (Fig. 3):

27 November 2017. This is how far I got today. I noticed how important it is to try and feel the story behind each part of the landscape, so this is not a matter of just adding stripes, but I need to feel my way round both reality and the developing composition (Fig. 4):

28 November 2016. Today I worked some more on this painting, adding new patterns with care, changing the colours of older ones and trying to guide the viewer through the image (Fig. 5):

I think that I should leave it where it is now. The composition feels complete to me, for whatever reason. In order to make it a working painting, however, I would need to apply paint with greater consistency across the whole support. It was an interesting experiment and quite revealing regarding the thought processes involved in the abstraction of patterns taken from the real world.
