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, Winter Evening

February 12, 2012 G Dan Mitchell Leave a comment

Motion-blurred photograph of low-flying Ross’s geese on a winter evening in California’s Central Valley.

From time to time I experiment with longer exposure photographs of birds in flight. The idea is that allowing the image to blur as the birds move might suggest their constant motion more effectively than the more typical approach of stopping the motion. Here not only was the exposure relatively long (I think it was 1/30 second) but I was shooting with a long telephoto which also amplifies the motion of subject and camera.

I’m thinking of this as a “study” for future photographs of these Ross’s geese and similar birds that will work with this idea of motion blur. Making this shot let me get a bit closer to understanding the most likely times to find the birds lifting off in the evening, and the best time to try to catch this with a bit of the last sunlight before sunset. I was also able to slightly better establish the shutter speed I would like to work with for this kind of image. The idea is to keep just barely enough shape in the birds that you can recognize what they are, but to allow the motion to blur things enough to eliminate the hyper-sharp realistic quality of the scene and to let the motion blur imply something about the actual flying motion of the birds.

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.

Eureka Dunes and Last Chance Range, Morning

February 7, 2012 G Dan Mitchell Leave a comment

Morning light on the Eureka Dunes and the hills of the Last Chance Range, Death Valley National Park.

While I love – who doesn’t? – the golden hour light on the desert dunes and hills and valleys, I also like to seek out the subtler and more “atmospheric” effects that are often frequently seen in this terrain. I had spent the (very cold!) night alone out here in Eureka Valley. I woke up fairly early, though with the sun having to rise past the ridge of the Last Chance Range, the light did not come early. I soon packed up my camp – which largely meant rearranging stuff in my vehicle – and before long started the drive out toward Lone Pine and my trip back home over Tioga Pass.

But first I planned to stop just a ways away from the camping area so that I could use a long lens to photograph the dunes against the background of the higher surrounding peaks. By the time I did this it was after 9:00 a.m. and the early morning golden hour light was long gone, replaced by the soft and hazy bluish light that is more typical during daylight hours. However, the sun was still low enough to glance across the dunes at a fairly low angle and to backlight the dunes and the mountains behind them. The idea here was to juxtapose some of the different textures, lines, curves, and angles of this landscape – the curving forms of the dunes near the bottom of the frame, the sharply delineated sunlit ridges of the upper dunes, the faint view of jagged and stratified rocks in the low peaks beyond them, the further ridge inclining the opposite direction from the dunes, and the much fainter texture of the huge valley in the distance.
