Is there anything better than the buzz you get once you find an idea that will work? My concept for Photo 51 has evolved to a tri-partite piece. I have spent lots of time researching imagery and quotes and now have all of the elements nailed down. It feels right - walks the line between representational and abstract and is dense with meaning. I am comfortable with the fact that most viewers won't 'get' it.
I am happy to report that I will be able to include an ivory tower in a piece destined for a show with structure as a theme. So much for my commitment to avoid architecture.
While I was Googling I had another idea about structure. It is also based in my experience and addresses an issue I care about. I will let it roll around in my head for a while and see whether it evolves.
