Photo of the Week – October 3, 2013

I found this robber fly perched in the prairie early Monday morning.  Although it was fairly breezy, the light was good enough to attempt a photo.  I’m glad I decided to give it a try.

Ten years ago, I wouldn’t have even considered attempting this photo.  When I was shooting with slow speed slide film, I loved the saturated color of Fuji Velvia, but every time I clicked the shutter it cost me about 34 cents in film/processing.  That kind of cost made me pretty leery of trying to photograph something like a flower that was blowing around in the wind.  A shot that came back blurry because the subject was moving too fast cost me just as much as a nice sharp image, so I couldn’t afford to “miss” very many times.  I would often take 3-4 versions of the same shot to make sure I got the exposure and focus correct, but even that was costing me about a dollar per good image.

This week, I photographed the above robber fly for about 5 minutes.  Within that time, I took 162 images.  The vast majority of those were blurry because the wind was swinging the fly and its perch so much I couldn’t focus and shoot fast enough to keep up.  I ended up with only a few sharp images in three different compositions.  Ten years ago, taking 162 photos would have meant about four and a half rolls of slide film and would have cost me about $44.  This week, it just meant I had to sort through 162 images to find the good ones – something that took just a few minutes.

Digital photography can sometimes make me a little lazy because it’s tempting to let some of the fundamentals of exposure and composition slide and try to fix things later with digital processing and cropping (though I usually don’t do much of that, and there’s still no substitute for getting it right in the field).  On the other hand, digital photography allows me to take risks that would have been unthinkable (or at least really expensive) in the old days.  Blurry photos don’t cost a thing now, and can often be deleted in the field.  Just as important, I can make sure I’ve got the shot I want before I leave, instead of discovering it days later when my slides come back from being processed.  Overall, it’s a pretty good time to be a photographer.

Just for fun, here are some of the other images from the brief photo session with the robber fly.

Photo of the Week – September 26, 2013

If found this dragonfly encased in dew a couple weeks ago as I walked through a small prairie here in Aurora.  I’m sure someone reading this will be able to tell me what species it is – I don’t know my dragonflies very well.

There were a couple of these in the prairie that morning, but we’ve also been seeing some bigger groups (flocks?  herds? swarms?) of other dragonfly species coming through Nebraska lately on their annual migrations.  Many more insect species migrate than you might expect, including (at least) moths, butterflies, and dragonflies.  I expect we’ll learn a tremendous amount about these phenomena during the next decade as efforts to study those migrations continue to ramp up.  Technology, including tiny radio transmitters, will help, as will volunteer citizen science efforts to gather sightings from across large areas.  It will be exciting to learn more about what seems an improbable but very interesting behavior from insects we don’t give nearly enough credit to.

You can learn more about insect migration from an earlier post I wrote on moths last year, as well as another post on intercontinental insect migrations.

Finally, if you are interested in nature photography or prairie ecology and are within driving distance of Lincoln, you might enjoy the lecture I’m giving tomorrow night for the Nebraska Statewide Arboretum.  More information on the event and ticket information is available here.
