Sometimes things just happen without you realising.
The subconscious acting, well, subconsciously. Making pictures of one thing but really making pictures of something else. It’s not until a while later that the pattern emerges, and there becomes a tie you hadn’t thought of that connects the images.
In the Hokianga I made a picture of ferns, where the geometry obviously attracted me. Lately I realise that I’ve been doing it for a while since without being aware of the attraction.
