From Introduction to Botany by Murray W. Nabors:
“During his botanical studies near Concord, Massachusetts, in 1851, Henry David Thoreau, author of Walden, discovered a rare, native climbing fern, Lygodium palmatum. ‘It is a most beautiful slender and delicate fern,’ he wrote, ‘twining like [a] vine about the meadow-sweet, panicled andromeda, golden-rods, etc., to the height of three feet or more and difficult to detach…. Our most beautiful fern, and most suitable for wreaths or garlands. It is rare.’
“In recent years, two exotic relatives of Thoreau’s fern have posed a serious ecological challenge in regions of the southern United States, particularly Florida. The climbing fern Lygodium microphyllum, native to parts of Southeast Asia and Australia, and the Japanese climbing fern Lygodium japonicum both entered the United States as horticultural plants for hanging baskets. They then escaped cultivation and became exotic pests. Like many introduced species, these Asian ferns thrive because they encounter few growth restrictions in their new geographical range. They grow rapidly and spread by wind-borne spores that may be carried 40 miles or more. These hardy ferns currently cover 40,000 acres in south Florida and have increased their range 100-fold over six years, surviving floods and droughts.
“Although beautiful, the ferns can be deadly to other plants, covering other vegetation in masses up to 0.6 meters (2 feet) thick. They kill other plants by cutting off the light or by sheer mass, even causing some trees to collapse under their weight. The vines, actually climbing leaves, may be up to 30.5 meters (100 feet) long, sometimes acting as fire ladders that rapidly carry flames into dry, dead trees. Masses of ferns readily break off during fires, carrying flames to new locations and resulting in the destruction of valuable forests.”
From “Fern Frond for John Wain” by Anthony Conran in Poetry Wales, edited by Meic Stephens:
Why don’t I send you
A fern really old —
Osmunda, with its massive
Stump-like bole?
Marattia or Angiopteris —
Squat little trees
That through the millennia
Inched down by degrees —
Dowagers of the rain forests
Left to their plight
In the hundred yard high
Struggle for light —
Or Lygodium, the last
Climbing fern —
Queens that hark back to a realm
Of no return?….
Evolved, sophisticated,
Able to hold
Its own where it chooses to be,
Withstanding the cold
Of our British winters
Like any birch or oak.
Red leaf burns on the hill.
Red dreams turn to smoke.
This fern has no royal blood —
Or if it has,
Only as much as is green
In a blade of grass.
Hello!
Here we have a series of photos of a fern called Lygodium japonicum — the Japanese Climbing Fern. When I took the photos, this fern — one of the members of the Lygodium genus, all of which love to climb and do so with energy and enthusiasm — had crept its way over a section of Oakland Cemetery’s gardens that was about thirty feet square. The amount of fern covering nearly everything in sight was stunning, and its abundance in very early spring surprised me. I had probably encountered the fern before, but it wasn’t until I saw this exuberant spread that I paid any attention to it, and I still wonder if it was intentionally planted there or it conquered the space on its own.
Plants in the Lygodium genus (especially Lygodium japonicum) are considered invasive in the U.S. Southeast — especially in Georgia and Florida — though I feel like there should be a separate category of such plants designated as “invasive but adorable.” Each leaf is no bigger than a dime or nickel, and as the plants unfurl and coil around whatever they encounter, they look like a soft green blanket. Before opening, the individual fronds produce a tiny version of the typical fern fiddlehead — appearing as points of yellow-green light in my photos — which take on the common triangular shape of a fern leaf as the plant matures. The vines have plenty of tensile strength; some of those I saw stood several feet high on their own accord, while waiting for the wind to toss them toward something they could latch onto.
In my imagination, all of this fern-ness was from one endless plant; though that was impossible to determine, which is the reason I’m just imagining it. In the plant’s name — Lygodium japonicum — “lygodium” is derived from a Greek word meaning “willowy” or “flexible” and “japonicum” reflects the plant’s native history in Japan. The excerpt from the poem “Fern Frond for John Wain” contrasts the Japanese Climbing Fern with several others that exhibit more common fern-style (click the links in the poem if you’d like to read more about them), and interprets the evolution of this viney fern within the context of British imperial explorations that brought plants from countries like Japan to Europe in the 18th and 19th centuries.
In addition to giving me a new plant to learn about, these photos ended up being a fun study in differences between what we perceive with our eyes and what a camera sees. Here, for example, are three of the photos from this series as they came out of the camera:
Just to the left of center in these photos, you can see what I considered the subject of the image: the vines entwined on the black fencepost, where they had climbed about six feet above ground level, supported by the post. I took photos at several different zoom levels to get separation between the vine on the post and the rest of the scene. A challenge, of course, was to get the vine adequately focused so that I could make it the subject of the photo with some clever editing in Lightroom, since even the slightest breeze led the fern to try to wiggle out of focus.
As you can also see from the photos, it was an especially brighteous morning when I took them — which accounts for large swaths of intense highlighting throughout the background. When we look at a scene like this, we selectively exclude extraneous information (like all the bright light in the background) in favor of what we’ve chosen (if “chosen” is the right word) to focus on. This can be confusing to explain: while we use “focus” to describe both how our eyes work and how a camera works — it’s only our eyes (or brain) that selectively disregard elements of a scene based on what we think we want to see. The camera simply records the scene; our vision makes choices about what parts of the scene matter to us.
Memory and emotion come into play here also. I remember the scene as one about a vine climbing up a post — not as a vine climbing up a post amid overpowering backlighting — and as a feeling about the vine’s behavior and ability to enwrap itself so high above the ground around something without obvious points of attachment. So a lot of what goes on in post-processing is about narrowing the gap between what the camera has recorded and my memory of and reaction to a scene. One might say that’s the whole point of post-processing, to bring our images closer to how we attached significance to parts of them when the photographs were taken. It’s about what I saw, not necessarily what I photographed.
To describe what should happen to these photos in Lightroom goes something like this: the background brightness needs to be decreased (a lot!) and the presence of the vine on the post needs to be increased. For that there are no shortcuts or automation: the vine needs to be carefully masked as the subject in Lightroom (with a combination of object selection and brushing), then that mask gets duplicated and inverted so that the image is split into two parts: the vine (in the foreground) and everything else (in the background). Once that’s (easier said than) done, the two segments can be treated separately: the brightness, color saturation, and sharpness of the background can all be reduced; the brightness, color saturation, and sharpness of the foreground can all be amplified. A semi-infinite amount of time and several cups of coffee later, we end up with photos that look like this…
… where (hopefully, The Photographer thinks) your eyes first alight on the vine while the background registers simply as location context for the photo, with three-dimensionality or depth improved over the camera’s flatter interpretation.
Here are side-by-side pairs, where you can compare what the camera saw to what the human saw by selecting the first image and paging through all six as before-and-after versions:
And here are three other examples — which got similar treatment — showing the difference between each scene as the camera interpreted it, and how I saw them at the time.
We have come to the end of the words…. Thanks for reading and taking a look!
