Preparing the Image

I want to achieve a clear record of the post top at the moment the photograph is taken. I want the photograph to record the post top in a manner that maximises the potential to recognise its earlier incarnations and determine any changes.

The tide and weather conditions are the main inhibitors of achieving the`ideal’ photograph of the post top. The changing tidal rhythms can restrict access to some post tops and the movement of the shingle can obscure the post completely. 

Masking the post top from its natural background.

When I started photographing the groyne post tops I knew that I wanted to isolate the post top from its background. I want the post top to be the focus. To achieve this I edit the photograph using Photoshop.

I think of masking as the process of isolating the post top from its background by producing one or two templates that I can overlay. I become fascinated by achieving the edge, the boundary between the post top and the pebble background of the photographed image.am

The process of selecting the edge begins with looking at a complete view of the image photographed. This repeats what I did in framing and taking the photograph – I check if the post top is in frame.

Then, I check if there is a clear edge. Is the edge of the post top worn in such a way that there are two or more potential edges? Is there a clear transition from to the edge? If so, what type of transition: curved edge, sloping edge, off-centre, off-horizontal picture plane? If there are two possible boundaries I often work on the outer edge first and then do the inner edge. Seeing both gives a comparison with which to decide which edge to use in processing the image.

Masking the post top to exclude the background is both an on-going practical and intellectual investigation of the complexity of boundaries. They become invisible from a distance and some edges that seem clear, become confused and complex when viewed close-up.
