“I am a 59-year-old mathematics lecturer and have only recently taken up photography seriously. I like different subjects, images that have geometric patterns or warm light effects, and items that may be environmentally not quite desirable but make symmetric abstract shapes.”
You look at a shot like this and wonder how anyone could know which cable leads where. It is bad enough trying to sort out the cable connections behind my TV and hi-fi system. I like these kinds of photos because of the patterns created with the multiple criss-cross lines, and it is also a reminder of how aerial cables were very much a feature of our towns and cities before underground cabling became commonplace.
When I opened this photo I noticed it had been saved as a JPEG using a heavy, level 3 compression. This JPEG setting is most unsuitable for a picture as detailed as this, and if you look at this close-up view (below) you should be able to see the JPEG artefacts showing along the wire edges.

To counter this, I duplicated the Background layer and applied a Smart Blur filter (with settings Radius 3, Threshold 15) and then added a layer mask so I could hide the filtered layer over the main pole area. This quick repair managed to convincingly hide all of the troublesome artefacts.
