If I make an image with a wall in it then those who know me would expect some geometric patterns, shadows etc. Maybe that is why this caused me to pause long enough as I walked past to capture an image that was not my 'usual”. Sometimes, as Ian and others have said recently, we need to get out of our own way. In this case it was a case of capturing something opposite to what I might normally do. There is no single answer to this business of making images.
