Migratory Birds in Twilight, Central Valley

February 13, 2012 G Dan Mitchell 3 Comments

Migratory birds flly though the twillight winter sky above California’s Central Valley and the Coast Range.

I made this photograph when it was almost too dark to see clearly. In fact, when I packed up and drove away a few minutes later, it was so dark that I momentarily got mildly lost on my way out of the refuge! Long after the sun had set, and at the time when perhaps the most intense sky colors appear, the migratory birds were still in flight above the Central Valley, often silhouetted against the colorful dusk sky just above the horizon.

This photograph is going to get a bit more technical explanation than usual. I had a 100-400mm telephoto on the camera at this point since I had been photographing the birds in a variety of ways, including trying to fill the frame with one or a few birds. While some might say that shooting a prime lens of this length could have some image quality advantages, this photograph wouldn’t have happened if I had been shooting, say, a 400mm prime. Since I wanted to move quickly from targeting small sections of the surroundings or even individual birds to making photographs that attempt to portray the larger landscape within which the birds are found, I frequently found myself moving quickly to much shorter focal lengths. Here, I realized that I might be able to “zoom out” and include some of the birds in flight high above the valley and the distant mountains in the context of their surroundings. So I shot this at something like 130mm. In addition, because the scene includes subjects that are not that far away (like the trees) and those at much greater distances (like the hills), depth of field was an issue with the longer focal lengths. I couldn’t shoot wide open without some excessive focus issues, so I stopped down to f/11. Think about that for a moment: shooting in extremely low light, stopped down to try to maintain some depth of field… and needing use a shutter speed allowing me to get some definition out of birds flying through the scene. This is essentially being caught between a rock and a hard place… and another rock. With the camera on the tripod, but still aimed manually, I used a shutter speed of 1/13 second and turned image-stabilization on. With all of this stuff pushing boundaries of shutter speed and aperture… my only option was to increase the ISO to 1600. For landscape work. Here’s the thing… in the end, while there was more noise in this photograph than if ISO 100 were possible, it isn’t that bad and probably wouldn’t even be visible to viewers of a print. While I’m usually persistent in my view that little technical differences among cameras don’t amount to much, in this case it was because current cameras make it possible to shoot in ways that were essentially impossible a decade ago that I could get this photograph at all.

Ross’s Geese Taking Flight, Sunset

February 10, 2012 G Dan Mitchell 3 Comments

A large flock of Ross’s geese takes flight in sunset light, Merced National Wildlife Refuge, California.

Every time I go back to this location, it seems to just get better. On this early February evening I had quickly driven over the hill from the San Francisco Bay Area – well, OK, it is a two-hour drive – in time to arrive shortly before sunset and join a group of friends who had come down from the Mariposa, California area to photograph the same subject. I drove out around the “auto tour” route to a spot where I had shot just a week ago, near a viewing platform. Just past this point, there were thousands and thousands of (mostly, I presume) Ross’ geese filling a large pond right next to the gravel road. I set up and gradually, bit by slow bit, moved myself closer to the pond, working carefully to avoid spooking the birds. Eventually I got into position perhaps 20 feet from the pond.

Initially I photographed the birds that were settled in on the pond. As we did this, more birds flew overhead, and some joined this gigantic flock. But the light still wasn’t quite great. As actual sunset approached, the geese began to lift off in large groups. It seemed like there would be some momentary electricity in the air – perhaps I was just sensing a change in their calls – and suddenly a few hundred would simultaneously take off in a large group. I knew I wanted to try to get some photographs of these groups, and I also figured that ideally I would like a bit of cross-light from the very low and warm-colored sun and, if I could manage to pull it off, I would want to get some sort of landscape-ish background of trees and ponds and the distant hills in the golden evening light. I made several attempts before I captured this moment during which the group had just risen enough to mostly clear the trees across the pond.

Sandhill Cranes, Dusk

The sandhill cranes are amazing creatures. On the ground they seem rather ungainly, but in the air they seem, to me at least, to fly with remarkable grace and strength. Several things can make them tricky to photograph. On the ground, they are frequently in less than photogenic locations such as turned under fields, and they are skittish, moving away quickly if you come too close. In flight they can appear and disappear quickly, and if you aren’t looking the right direction you can miss them as they fly over. And they seem to come in waves – you can wait for a while without seeing any of them, let down your guard and become distracted, the suddenly groups of them seem to appear.

I had fewer opportunities to photograph them close up at Merced National Wildlife Refuge on this evening than I had earlier in the day back north at Woodbridge Road. But a few did come close and I managed to photograph this portion of a large group that flew over as the evening light was turning portions of the sky pink and purple.

Autumn Tamarisk

Tamarisk plants with autumn foliage on the banks of a desert stream, Grand Staircase-Escalante National Monument

I photographed these tamarisk plants with autumn colors on a cold and extremely windy day in the Grand Staircase-Escalante National Monument – most likely, if memory serves, during a brief lull in the wind. It was a beautiful and invigorating day – but certainly not one that was conducive to photographing autumn foliage! We did spend the better part of the day in this canyon, but the wind increased and by the end of our work it was almost strong enough to occasionally stop us in our tracks on the hike out… and then it started to rain!

Tamarisk plants can offer some of the most varied colors of almost any plant, though they are often overlooked because they can easily look drab, especially in daytime light, and because their form is not classically tree-like. But depending on the season and the lighting they can have almost every color imaginable: reds yellow, purple, blue, tan, green. This small group of plants was, obviously, sporting brilliant autumn colors. But, in addition, it was lit by the reflected glow of warm colored light coming from a nearby cliff face in full sun.
