One of the FPOTY themes is Textures and Patterns in nature and I went up there to get some ideas and see what worked for that theme but also I spend quite a lot of my time in karst landscapes and essentially they are an expression of change over time, the limestone is etched by acidic water and I suppose I was trying to get a sense of that energy and change. Also a lot of karst features are fascinating up close, endlessly varied at many scales but just grey on grey so very hard to photograph, so again it was may be an attempt to engender some interest.What were you expressing with the first shot? My poor brain can't read your meaning.
