Coquina at Washington Oaks

According to the Wiki on the subject, Coquina is a relatively rare rock made up of masses of ancient shells and shell fragments loosely cemented together, some still largely intact. It is found in isolated outcrops along the Atlantic coast, from St. Augustine to Palm Beach, FL, and in one spot in North Carolina. There is also an outcrop in New Zealand. It is soft, so soft that it can only be used for building after air drying or curing for up to 3 years. The Fort in St. Augustine is built from it…which was a considerable advantage, since the soft walls absorbed (literally) canon ball fire better than harder stone would have.

It is the softness that, in large part, also gives Coquina its photographic interest. The waves shape it into an incredible variety of forms as they wash over it. Close in, the structure of the stone itself is of interest, as a study in shape and texture; especially as the density of the surface and its structure, as well as the color,  varies greatly from stone to stone.

All with the Canon SX20IS. 1) 28mm @ F4.0 @ 1/1000th @ ISO 80, 2) 28mm @ F4.5 @ 1/250th @ ISO 80, 3) 250mm macro @ F5.0 @ 1/640th @ ISO 80, 4) 200mm macro @ F5.0 @ 1/1000 @ ISO 80.

The first two got my standard landscape treatment in Lightroom. Recovery for the sky, a touch of Fill Light for the foreground, Blackpoint right, added Clarity and just a bit of Vibrance. Sharpen landscape preset. The close ups received similar treatment but with very little Recovery and less Fill Light. Less of everything actually, except sharpen.

From St. Augustine FL 2010.
