9/5/2010: Jordan Pond and the Bubbles

Happy Sunday!

The three mile loop around Jordan Pond is one of my favorite hikes (walks?) in Acadia National Park, and that is saying quite a bit as there are a lot of hikes in Acadia that I really like. Of course, the fact that we have had a daughter (or two) working at the Jordan Pond House the past 6 summers only adds to the attraction. It does not matter how many times I walk this walk…there is always something new to see, even if it only the angle of the light, or the pattern of the ripples in the sun, or the way fog drapes the cedars on the south shore. Always something new. But then new is a gift we receive from the author all things new, inside, before we can see it outside. Or at least that is the way I see it.

This is another experiment in HDR using two SX20IS exposures 3EV apart and Photomatix to blend them. Final adjustments for Blackpoint, Clarity, Vibrance and Sharpness in Lightroom, plus some distortion correction for the challenging perspective.

9/3/2010: Cadillac Mountain

On the way back from dropping daughter #3 off at College, we stopped for the afternoon and night in Bar Harbor…mostly to see daughter #1 and #2. Daughter #1 lives there, and daughter #2 is working there in Acadia National Park for the summer. No visit to Acadia, of course, is complete without a drive to the top of Mt. Cadillac. Even though we only had a few hours there, after a hike around Jordan Pond (also a must as far as I am concerned), we drove to the summit on the way back to Bar Harbor and dinner. It was not a pristine day…there was a good deal of haze over the ocean, but the late afternoon/early evening light was interesting on the stone of the peak.

This is an HDR using two exposures and Photomatix Lite. In realty I am not sure I gained much through the two exposures. I am pretty sure I could have adjusted a single exposure in Lightroom for close to this effect. Still, the tone-mapping for detail in Photomatix certainly brought up all the character in the foreground rocks, and I am certain I could not have pulled up the greens in the trees to this level. The greens have always frustrated me in shots from Cadillac, since exposing for rock and sky always leaves the greens running toward black. Keeping the greens vibrant gives this shot three strong layers instead of two. This is good.

Canon SX20IS at 28mm equivalent. Two shots separated by 3 EV using the Exposure Compensation dial.

Photomatix as above. Adjusted for Blackpoint, Clarity, Vibrance, and Sharpness in Lightroom.

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.
