Photo of the Week – January 12, 2018

Tomorrow, I’m leading a photography workshop; something I rarely do.  I’m looking forward to the workshop, but always feel a little funny teaching photography for a couple reasons.  First, photography is a very individual activity, by which I mean that every photographer interprets the world in their own way.  Because of that, trying to “teach” someone how to be a photographer seems like kind of a crazy thing.  As a result, I’ll be talking very little about the interpretive part of photography, and concentrating mostly on the mechanics of how cameras work and how to use that knowledge to create art.  Then I’ll try to provide a lot of examples of what’s possible with photography, hoping to inspire people to develop their own vision.

Bugs (in the broad, non-scientific sense) and flowers are subjects I feel comfortable with.  Landscapes, wildlife, and other subjects are much less in my wheelhouse.

The second reason I hesitate to lead workshops in photography is that I feel pretty limited in my own knowledge.  After all, I spend most of my time on my knees, photographing tiny bugs and flowers, and I’ve learned how to do that using the few pieces of equipment I happen to own.  I suppose I know more than the average person, but I don’t feel like I have the kind of broad knowledge of camera equipment or techniques  held by many photographers I admire; people like Michael Forsberg, Clay Bolt, Piotr Naskrecki, and Joel Sartore.  Also, when I stray from my narrow range of expertise, I tend to make a lot of mistakes.  That seems to happen particularly often when I attempt night time photography.

The latest example of my night time photography foibles came during the trip Kim and I made to the Niobrara Valley Preserve over the holiday season.  The weather was very cold while we were there, but I braved the temperatures one night and went out to photograph in the light of a half moon.  I worked along the river, mostly, shooting starry scenes with the river and silhouetted trees in the foreground.  Because of the moonlight, the stars weren’t really popping in the photos, so I decided to switch and shoot the moon instead.  I wandered over to “the chute”‘ a locally famous waterfall on the Niobrara River, right near the Norden Bridge.  Because of the sub-zero temperatures, much of the river was frozen, but the water pouring over the falls was still ice free, and there was fog (is it really called fog in those conditions?) coming off the falls and rising up toward the moon.  It was a magical scene, and I worked for about an hour to capture images of it.

Here is one of the three images I brought back from more than an hour photographing ice and water in the moonlight.  All three photos were taken with a Tokina 12-28mm lens at ISO 800, f/4, and a shutter speed of 6 seconds.

The log in this scene has been stuck on the same ledge for several years now. I keep waiting for a big water event to wash it away…

Unfortunately, my mind must have been as frozen as the the ice I was (carefully!) walking around on.  I completely forgot to change my aperture settings on the camera from the wide open settings I’d been using for star photos to settings that would give me more depth-of-field.  And because it was dark, I had a hard time focusing anyway, and didn’t notice how out of focus many of my foregrounds were.  This led to a lot of almost great photos with blurry images of rocks, ice, and/or water in the foreground.  Out of that entire hour, I ended up with three images that were fairly sharp all the way across – only because I was far enough from the foreground for it to be sharp.  Anything with a nice close waterfall in the foreground and starry sky in the background turned out to be junk.

This was my favorite of the three decent shots, mainly because there was something interesting in the foreground (though I had a couple others with that ice formation much closer to the camera that would have been spectacular…)

I sometimes make mistakes photographing bugs and flowers too, but night time photography always seems to give me big problems.  In fact, one of my biggest recurring issues with bug/flower photography is tied to night photography… I very often forget to reset my ISO after shooting star photos the night before and end up taking grainy photos of flowers with an obscene ISO of 2500 or so.  I’m telling you – night time photography is out to get me.  I’d like to think I’ll get better at it if I do more of it, and I’ve been making an effort in that regard, but so far, not much luck.  Fortunately, there are lots of bugs and flowers to photograph during the daylight hours, so my ego hasn’t completely deflated.

Gee, this wasn’t a great advertisement for my photo workshop tomorrow, was it?  If you’ve signed up and are reading this, I promise I’ll do my best to make it worth your time.  The good news is that the workshop happens during the day – not at night!

Catching Up on Summer Photos

I spend most of my summers in the field, wandering around in prairies collecting data, making observations, and taking photos.  Lots and lots of photos.  So many photos that I only have time and space to post a small percentage of my favorites here on this blog.

This week, I’ve been going through my 2017 photos, trying to select a manageable number for my annual “Best Photos of” feature, which will be coming in the next week or two.  While doing that, I came across quite a few photos I really liked but haven’t posted yet.  Here is a batch of previously unposted images from the Niobrara Valley Preserve from this summer, along with some brief natural history notes.

A gorgeous northern leopard frog stares at me from the bank of the Niobrara Valley Preserve. I like this photo for a lot of reasons, but one of the biggest reasons is that my daughter spotted the frog while we were out exploring together.  The northern leopard frog can be distinguished from the plains leopard frog because the two lines on the back of the northern are continuous, and the lines on the plains leopard are broken.

We are trying to better understand the potential ecological values of short vegetation structure and exposed soil in the Nebraska Sandhills. It’s a set of habitat conditions most ranchers manage against, and we’re wondering what species might benefit from having a little more around.  If nothing else, the patterns found in wind-blown sand are aesthetically pleasing.

One species we know thrives with lots of bare sand is the Ord’s kangaroo rat (Dipodomys ordii). K-rat tracks are abundant in bare sand, distinguished by the relatively large size of the foot prints and the tail marks between them.

This was one of the first plains sunflowers (Helianthus petiolaris) to bloom this summer, but as the summer progressed, sunflower populations exploded, especially where we’d burned in the spring.

Ants appreciate the extrafloral nectar produced by plains sunflowers, and presumably help suppress numbers of herbivorous insects on those sunflowers – notwithstanding the well-armored weevil shown here.

Mating assassin bugs on a plains sunflower. These ambush predators are often seen hunting on the sunflowers as well, taking advantage of abundant insects in search of accessible and nutritious pollen and nectar.

The day’s last beams of sunlight stream across our public hiking trail above the Niobrara River back in June of this year.

As I prepare for the “Best Photos of” post coming up, please let me know if you have a favorite photo or two from the year.  It’s awfully hard for me narrow them down…
