Seconds after taking this shot, at f/4, I changed the f-stop to 29 and captured these blossoms with the environment in focus (yesterday’s posting). At f/4 focus is a challenge and I was not happy with the detail of the foreground blossom.

Dual Pixel Raw comparison
I am in the experimentation phase of learning the new camera, so in spite of the 100% file size increase I turned on the Dual Pixel Raw feature. The two photos are from the same file. My impression is the adjustment improved the foreground flower details. Is it my imagination?
Hepatica blossoms are the focal point here. Two land snail shells rested fortuitously below, a white and dark brown. The white shell (Scientific Name: Neohelix albolabris) is seen here. In life, the shell aperture reflective lip gives the species name, from Latin root words “albo” (white) and “labris” (lip), and the popular name, “Whitelip.” Look closely to see a series of ridges, an identifying feature apparent in this specimen. There was a live specimen in our yard, just yesterday. Busy with chores, no camera at hand.

Hepatica positioned perfectly above the trail, sprouting from moss, a grouping of the plant and flowers.
Scientific Name: Hepatica nobilis var. obtusa. I found the two land snail shells this session, I identified it as Neohelix albolabris, and positioned it in this shot to lend interest. In a future posting you will see the shell where it was found.

Hepatica Blossoms
Six unrelated young adults, all female and without masks, not following social distancing guidelines, passed as a group just before I set up for this shot. I heard them coming and made plenty of space between them and me. COVID-19 testing in Tompkins continues to find several positive cases each week.
Finding an appropriate combination of settings for this grouping was a puzzle. My goal was to bring the flowers and surrounding into focus with intermittent breezes. The f-stop needed to be high to accommodate the depth with minimal exposure duration as the flowers moved in the slightest breeze. The solution was a high ISO (2500) and f-stop (32), yielding a 1/3 second exposure (Not fast). The compromise was patiently waiting for a break in the breezes.

Just opened flowers on long hairy stems, tiny anemones. A crawl and tripod we needed to capture these. The scene scale is revealed by the dried leaves from last autumn.

Hepatica Blossoms
I call these anemones from the disputations among taxonomists. All agree there is some relationship and differ in the degree. Classifications add a designation “tribe” before genus (hepatica). Alternatively, the genus is designated Anemone instead of Hepatica . A common name for anemones is “wind-flower” for how the flower is sensitive to a slight breeze, on these long stems.
This is the first hepatica capture of the session. There was no breeze at this time and the ISO is 800, f-stop 29 (lending some definition of the background, less than I’d expect) and a relatively slow exposure of 1/4 second. The 100 mm macro lens on a tripod mounted camera.

Here we have two photographs from the end of the April 20, 2020 session. I finished a series of macro Hepatica and, tired (emotionally, not physically) and not wanting to step up the slope, captured the following grouping of a single Red Trillium, lit by a bolt of sunlight, White Hepatica, fern and the budding White Trillim from yesterday’s post. Not the same trillium, a continuation of all the individuals in bud.

Wildflower Grouping
These were 15 feet or so up the slope above the South Rim Trail. I used the 100 mm macro lens, with the spring breezes ISO set to 2500, f/5.6 for a 1/200 exposure.
Not far away, also upslope, was this flower grouping against a moss covered log. Park forestry leaves fallen trees in place to return to the soil. Camera settings are the same.
Lobe leaved Hepatica
Both photographs were handheld.

Wildflowers flourished where the slope turned to the north and late afternoon light spread across the small ravine created by a small stream. This early in the season White Trillium buds were forming between three green bracts.

Trillium Grandiflorium
The above photograph taken handheld with a variable zoom lens captures the plant and environment. On the forest floor is twig of hemlock, probably knocked off by squirrels feeding on the tiny cones. Oak leaves from last season frame the dark green bracts. We also see a few wintergreen leaves and the rich soil.
With the low light ISO is 2000, the f-stop of 5.6 allowed crisp details of the hemlock and wintergreen, the focus is soft on the oak leaves. Where is topography allowed sunlight, the White Trillium were a bit further along. Here is a bud opening.
Trillium Grandiflorium
Here I used a travel tripod and a macro lens with f-stop opened up to 3.2, not lens maximum, and all but the forward bract tip are in focus. A lower camera angle places surroundings in distance, allowing all to be blurred unrecognizable: the plant is the star of this shot. ISO 800 with the ample light. I was struggling with the spring breezes, having to wait for a break to take each exposure.
