Author and map maker Tim Robinson describes the project like so –

Cashman’s procedure has been to select a number of sites in north Connemara and, over a year, visit each one at about the same time of day to take a photograph of the scene.

When the results are shown in sequence several kinds of changes make themselves apparent. Most obviously, the annual rhythms of the advancing season, the waxing and waning of vegetation, the coming of darker days ...

Then (in the sequences that incorporate a sight of the sea) there are the tidal variations. Since the morning high tide, for instance, occurs about half an hour later from one day to the next, the camera captures the tide at a different stage in each photograph, varying over a fortnight or so from high tide through low tide and back to high tide.

And then there are the haphazard appearances ad disappearances from one shot to the next of a boat or a seabird or a passer-by. The effect is ghostly: the evanescence of human and animal life is contrasted with and woven into the grand cycles of sea and sky.
