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.

Track

Track: art in the artifacts of change.

Of course this is not really a picture of a footprint. The footprint only provides a point of focus for what is essentially a study in texture and shape…and the way the low sun of early evening interacts. Rock, sand, snail shells, and broken crab. A feast of color, light, and texture.

For this kind of shot, you have to wake up your eye…your inner eye…the part of you that sees image possibilities in the chance arrangements (if you believe in chance) of the world around you. The Art in the artifacts of change. (Maybe I should copyright that phrase before someone steals it 🙂

Sony DSC H50 at about 285mm equivalent to frame the shot. F4.0 @ 1/250th @ ISO 100. Programed auto.

In Lightroom, simple added Clarity and Vibrance, a touch of Recovery for the crab shell, a touch of blackpoint for overall depth, and the Landscape sharpen preset.

Shell Brook

Shell Brook

South of St. Augustine, the white Florida sand is mixed with crushed shells. The Atlantic is a much more vigorous shell crusher than the Gulf of Mexico. Where rock outcroppings occur, as here, the shells heap up and form interesting patterns. Streams. Brooks. Little oceans of shell.

Taken from beach level using the fold out LCD panel on the H50.

Sony DSC H50 at about 36mm equivalent. F8.0 @ 1/400th @ ISO 100. Programed Auto.

Because of the range of light and dark here, I used a considerable amount of Fill Light in Lr. Standard Clarity and Vibrance for the H50, Landscape sharpen preset.
