Various photos, various techniques

 I'm always playing with different photographic techniques. A few different (for me) attempts follow.

A 1st-cycle Ring-billed Gull prepares to drop onto the water. Bernie Master and I headed to Springfield Lake near Akron yesterday, to try and see a Kelp Gull that has been in the area for over a week. We were joined by well over a hundred other birders, but no luck - the rare gull stood all of us up. Such is life on the rare bird circuit.

We arrived before it was light, and as dawn brightened the landscape and it became ever more apparent that the Kelp Gull was not on the lake, I turned the lens to much more mundane Ring-billed Gulls. The light was horrid in nearly every way - wasn't much of it, and what there was came from a suboptimal direction. Normally I'd probably not even click the shutter in such a situation.

But what the heck. I decided to try for some "creative blurs". I've seen photos dubbed as creative blurs which to me have been bad photos masquerading under an artsy name. And I've seen creative blurs which looked cool and very out-of-the-box. I don't know where mine stands on the scale of good to bad, but I rather like it. This gull was shot with the Canon 7D Mark II and 500mm f/4 II + 1.4x extender, at f/5.6, ISO 1250, 1/320, with +2/3rds exposure compensation.

This cliff face is in Clear Creek Metro Park, and is a local legend known as Written Rock. Back in the day, it was covered with colorful graffiti from toe to crest. I used to marvel at how the taggers could access the inaccessible areas of the cliff to spray their drivel. When Franklin County Metro Parks took over Clear Creek, they blasted the rocks clean and have kept it that way. Written Rock is an exceptionally colorful piece of sandstone, but hard to photograph. The high contrast between dark and light areas of the cliff, and the brightly lit sky around the borders, means some parts of the image will be greatly over or under exposed.

Enter High Dynamic Range (HDR) photography. I'd wanted to fool with HDR for some time, and have finally gotten around to it. Here's how it works: Select the composition, and frame your image with the camera mounted on a tripod. A remote shutter release is best, as you don't want the camera to move at all between shots. Then take a series of three to five images ranging from overexposed enough to light the darkest areas, to underexposed enough to not blow out the brightest areas. Then use special software (I used HDRsoft) to blend them all together. The result should be a composite photo that is fairly evenly lit throughout - something that couldn't really be done with a single image, at least without all manner of post-processing work that would be beyond me.

As always, click the photo to expand

This is Rock House in the Hocking Hills, and this composition is fraught with peril for the photographer. I am crouched in the shady apse of a rock overhang, shooting out into much brighter light of varying degrees. Such a situation is where HDR excels, bringing up the dark areas and toning down the bright areas. I used five different images to create this shot.

Ash Cave, one of the largest and most beautiful of the Hocking Hills' incredible rock formations. This was my first effort at intentionally taking images in the field with HDR in mind. As with the previous two, five images of different exposures were melded together to create the image. This photo is closer to what the eye sees than what is recorded by a single photo. Your eyes moderate the very bright light from the sky in the photo's upper lefthand corner, and brighten the shady recesses on the right. A single photo would be overexposed on the left, or grossly underexposed on the right. HDR allows one to have their photographic cake, and eat it, too.

I look forward to more experimentation, HDR and otherwise.

"bad" photos really make me appreciate the human eye (brain?)

I'd like to give you a huge compliment on the Rock House and Ash Cave photos. I have been there and this is exactly what it is like to view them. I've taken photos while visiting and I usually delete them because I never capture the true experience.

I continue to appreciate your technical commentary in companion with the engaging images.

The Pinching Beetle, a rather brutish looking bug

The world is awash in beetles, and they come in all shapes and sizes. Few of them can match the intimidation factor of a Pinching Beetle, Lucanus capreolus, though. Those formidable looking mandibles look like they could slice off a finger.

Today was one of those coolly diverse days. I started off down in Fayette County, visiting the farm of a friend. He has restored about 25 acres of wetlands, and the response by the animal community has been nothing short of phenomenal. Blizzards of dragonflies of many species, amphibians galore, and nesting Blue-winged Teal, Pied-billed Grebe, and Sora. Among MANY other things. And all in a short two years. Add water and they will come.

Then, working my way home, I ducked into a Madison County cemetery that has a thriving population of Thirteen-lined Ground Squirrels, and shot images of our native prairie dog. Then, I stopped at a spot along Little Darby Creek, waded on in, and procured some pretty nice shots of various stream bluets and dancers. …

Calliope Hummingbird in central Ohio!

A hatch-year male Calliope Hummingbird strikes a pose. Small but tough, the hummingbird was feeding actively yesterday in 39 F temperatures. It frequents feeders and gardens at a home in Delaware County, Ohio, about a half-hour north of Columbus.

Fortunately, the wayward hummer appeared at the home of Tania and Corey Perry. Tania is a birder, and knew right away that the hummingbird was something special. For a while, the identification was up in the air, which isn't surprising. The Calliope Hummingbird used to be placed in its own genus, Stellula, but has recently been submerged into the genus Selasphorus, which includes Allen's, Broad-tailed, and Rufous hummingbirds. The latter two, especially, are quite similar to the Calliope in subadult plumage. Rufous is the default "vagrant" hummingbird here, with dozens of records and birds turning up annually. There is but one Ohio record of Allen's Hummingbird, from late fall/early winter 2009. Ditto the Calliope Hummi…

Snowy owl photography tactics - and things NOT to do

A gorgeous juvenile female snowy owl briefly catches your narrator with its piercing gaze. It's doing its Linda Blair/Exorcist trick - twisting its head 180 degrees to look straight behind. Owls have 14 neck vertebrae - double our number - which allows them such flexibility.

These visitors from the high arctic have irrupted big time into Ohio and adjacent regions, with new birds coming to light nearly every day. Probably 80 or so have thus far been reported in the state, and some of them have stuck around favored spots and become local celebrities.

I went to visit one of these birds this morning - the animal above, which was found last Friday by Doug Overacker and Julie Karlson at C.J. Brown Reservoir near Springfield. In the four days since its discovery, many people have visited as is nearly always the case when one of these white wonders appears near a large population center or is otherwise very accessible.

And as is always the case, people want to photograph the owls. And th…
