Happy 4th of July fireworks!

Last night was Columbus, Ohio's major fireworks extravaganza - Red, White & Boom. This is the largest fireworks display in the state, and RWB's 37th year. I was there, and managed a number of satisfactory images.

If you're into fireworks, just scroll through the post and enjoy. Remember, as always you can click the photo to see an enlarged version.

If you're into photography, I've prefaced this post with some fireworks photography tips. Each of the images is captioned with the metadata for the photo, too.

As we all know, fireworks are amazing light shows of color and shape. It's natural to want to record them on pixels; keep a permanent memory of a very ephemeral festival of light. Shooting quality images of fireworks isn't too difficult, but it's a technical enough challenge to make blunders easy to commit, and crisp well-exposed images are quite rewarding. I know that most people who read this blog know me as a photographer of most things natural history, but I've yet to find a photographic outlet that I don't enjoy. Practicing on all manner of subjects will only make the photographer better at shooting his/her primary field of interest.

Anyway, here are some thoughts and tips for those of you interested in fireworks photography:

1) Case out the lay of the land beforehand. Frankly, one of the greatest challenges is finding a shooting locale not interfered with by unsightly buildings, wires, poles etc. I spent nearly two hours driving around and rejecting sites before the fireworks launch last night, and I know Columbus quite well. Some 500,000 people descend on downtown for this event, and I knew I didn't want to be in the thick of that. I was angling for a distant site that would keep me free of the masses, provide a largely unfettered view, allow me to include some of the downtown skyline, and be upwind (so that smoke from the fireworks would be less likely to create haze in my images). I finally found the best site I've hit on yet, and was in and out with no hassles and did not have to contend with throngs of people. The main thing I didn't like about this location is that ugly boxy building in the foreground. My search for an ultimate site will continue.

2) Don't be afraid to shoot from a far distance, or use a telephoto lens. While I would love to shoot RWB from its epicenter someday, with a wide-angle lens, I haven't managed to work that out yet in a way that I wouldn't mind dealing with. The images below were shot from a distance of 2.2 miles from the site of the fireworks launch. As long as atmospheric conditions are decent, this shouldn't be much of a problem, and actually has some advantages. For equipment, I used the Canon 5DS-R, and Canon's remarkable 200mm f/2L telephoto. Most people have a zoom lens that covers the 200mm zone and nearby ranges, thus are equipped for distant fireworks photography.

3) Tripod - an absolute must. We're talking very long exposures, and there is no possible way to handhold the camera over such time frames and create sharp images.

4) A remote shutter release. I use an inexpensive cord that plugs into the camera, and lets me activate/deactivate the shutter without ever touching the camera. Stillness is key here. Plus, you never have to look through the camera once all is set up - just watch the show, and work the shutter remotely at key times.

5) Composition. Select a swath of landscape that includes features of interest other than the fireworks, if possible. In this case, I used the neatly illuminated Lincoln LeVeque Tower to bookend the northern (left) side of the shot, and the Baker-Hostetler building on the other side. This composition allowed me to keep the fireworks as the dominant feature, but still include a stretch of downtown buildings for site context. Again, I wish that ugly box-like building wasn't in the foreground, but I'll keep hunting for the perfect locale.

7) Focus. It's vital to get sharp focus on the fireworks themselves. One advantage of working this far back from the show is that it's easier to get both the fireworks and the nearby buildings in reasonable focus. Fireworks bursts such as these are so large and bright that you should be able to auto focus on one of the first bursts, and thus set your focus that way. Once focus is dialed in, don't change it.

8) Try and fine tune all of your settings early on: focus, composition, levelness of camera, and camera settings. If you can dial everything in pronto, you'll be free to focus on creating images for the vast majority of the show.

9) If your camera has a built-in level - and many/most DSLR's do - use it. In such situations, a perfectly level photo is desirable.

10) Use Bulb Mode. Again, most if not all DSLR's have this mode, although it isn't often used. Bulb opens the shutter and keeps it open until you manually close it using - ideally - your remote shutter release. You could make an exposure that was hours long, or as long as your battery lasted, if you wanted. All of the following exposures were multi-seconds long, and some of them pushed a minute in duration.

11) Keep the ISO very low - ISO 100 is best. You'll be making long exposures, which means much light will be harvested by the camera's sensor, so high ISO's won't be necessary. And in ISO-world, lower is almost always better. The images will be cleaner and less grainy/noisy.

12) Use a small aperture. An f-stop between 8 and 16 will probably be best, but it'll require a bit of tweaking at the onset of shooting to find the sweet spot.

13) Experiment with ultra-long exposures by using a dark object to temporarily block the lens. For last night's work, I found that, depending on the color and intensity of the fireworks, I could not expose more than 10-15 seconds without overexposing the image, and we don't want overexposure. However, by leaving the shutter open, but temporarily covering the lens with a dark object every so often to avoid overexposure, you can create one image that displays numerous bursts of fireworks - far more bursts than could be captured without covering/uncovering the lens. This technique is as much art as science, and requires practice.

14) Be prepared to adapt to changing light. Brilliant white bursts of fireworks will necessitate shorter - sometimes significantly shorter - exposures than cooler lights, such as blue.

15) Try and make a quick study of each image on the camera's viewing screen immediately after creating it. By so doing, you'll quickly get a sense of what's working and what isn't, and what tweaks you'll have to make.

16) As always, as in any kind of shooting, use your camera's histogram to evaluate exposure, and make sure the camera's "highlight alert" feature is activated. The latter indicates overexposure by causing overexposed portions of the image as seen on the viewfinder to blink. If you get a case of the "blinkies", you know you've got to either shorten the length of exposure for that situation, or shut down the aperture some more, or some combination of both. Conversely, if the histogram and your eyes indicate underexposure, you'll have to open the aperture, or lengthen the exposure, or some combination of both.

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…
