I had so many different topics to choose from for my photographs for the day since we had a picnic by a lake. But my son chose the dandelion. I cannot see the details of the flower until I transformed it into white and black. Does anyone know why the conventional way to say it is "black and white"? Is it alphabetical? Does it roll off the tongue easier or because we are used to it? Just questions that come to mind after a long week...
