I just love to follow a line - with my eyes, along a path, while writing, dancing.
In photography, it is accepted that the eye follows lines into a photograph, so you should aim to place your point of interest where the line ends.
I'm talking about just this, this week in Better Pics for Business. I looked through my images and found some of my faves that demonstrate it.
Take a look at some of your fave pics and see if they have leading lines. I bet some of them do. Whether it is virtual, with light or with colour.
