I photographed Oxwich beach at the start of my walk this week. The shape may be a little less obvious in the shot below but it still reveals a bottleneck form. If from this angle the shape is a bottleneck, then the third image in the sequence below could only be described as a wedge. The shape seemed obvious to me and is the reason for taking the photo but I wanted to emphasise it more and experimented with the contrast in monochrome.
Having enjoyed the overexposed beach image I posted from the previous Taste of Gower walk at Llanmadoc, I increased the exposure on the last photo below as well. With almost no reference points in the image, what is real becomes abstract.
