AIRSHOW PREPARATIONS

T-6 Texan,   @600 mm, 1/250s, f/13, ISO100

The sound of propeller engines filled the air early in the morning during the last couple days, reminding us that the world’s largest airshow in Oshkosh, Wisconsin is coming up next week. As every year a number of historic airplanes are at the Dubuque Airport the week before, with the pilots training for the big event.

I went out in the afternoon and the weather conditions were just great for some aviation photography. Some big puffy clouds made for a nice background. As every year, there were a number T-6 Texans and some other airplanes parked but a few did still their practice at my arrival. The runway they used for starts and landing today is not far from the observation deck and I tried my luck with the planes coming in for landing out of the southeast.

There were two things I tried to accomplish. First it is nice to have a little bit of blue sky in the frame, not just the white and gray of the clouds. That of course was not always in my control. And second the props of the planes had to be blurred for a realistic sense of motion. To get there the shutter speed should be between 1/40s and 1/250s. The last was almost too fast for some pictures because the speed of the propeller plays also a role here. I can tell, my panning technique with the long lens was not superior today, I had a lot of misses. I definitely need more practice…

NATURE CLICKS #522 - BROWN SNAKE (STORERIA DEKAYI)

Brown Snake, Little Maquoketa River Valley, Heritage Trail

It was getting dark when we returned to the car from a little walk with our dog Cooper this evening. We had chosen a quiet section of the Heritage Trail for our hike, a little bit up in the valley, to keep the dog away from any firecracker noise that is part of the celebrations for Independence Day. Most dogs do not like this kind of noise…

Joan discovered this small Brown Snake on the trail. They are a nonvenomous species and prefer woodlands like we have them here in eastern Iowa. Years ago we had no problems finding this and other species in our woods but during the last few years we hardly see any. I wanted to document this not so common find and cranked up the ISO to 2500 and still shot only with a shutter speed of 1/30s. This is when vibration reduction in camera or lens becomes a useful feature. It helped that the snake went into a defensive pose while we took a few pictures. We kept the stress to a minimum and guided the critter off the trail with a stick. Luckily nobody came at the time of dusk anymore, but a bicycle accidentally driving over it wasn’t a good perspective for this beautiful Brown Snake…

NATURE CLICKS #505 - PROTHONOTARY WARBLER

Protonotary Warbler, Mines of Spain, iowa

A dream came true having finally, after many years of trying, a pair of Prothonotary Warblers in front of the lens last week. They were feeding their offspring at an old woodpecker hole in a dead tree log. I owe a big thank you to a photography friend, who discovered the location and gave me a call. Although the nest site is not far from a relative busy location in the Mines of Spain, it is not easy to access. My approach was very slow and careful and I was able to hide behind a layer of dense underbrush. The last thing a photographer should do is to disturb the birds. No photo is worth to risk the well-being of an animal. The warblers seemed to ignore my presence and never hesitated to approach the nest or fly away from it.

Both parents were feeding the young ones in the nest. They showed up in average intervals of about 6-7 minutes. I made a clear decision to shoot without the help of some fill flash, although the tree was in the shade. With the sun almost overhead, there was still enough light to make the warblers stand out against the tree. This required some slow shutter speeds, mostly between 1/80s and 1/125s at the widest aperture f6.3 of the SIGMA lens.

MISSISSIPPI RIVER STORIES 2020 #5 - MAKING SPEED VISIBLE

Wisconsin bridge, Mississippi River, Dubuque, Iowa

Dubuque has three bridges across the Mississippi River. The photo shows the highway bridge to the state of Wisconsin. The two other ones, connecting Iowa and Illinois, have been in my viewfinder quite often in the past. This one not so much. I went there last weekend to practice and experiment again with my graduated neutral density filters. Our vacation trip is coming up later this month and I like to be prepared for some new landscape explorations.

A lot of traffic on the river, with most boats slowly cruising and people enjoying a hot and sunny evening. We know there is always an exception and the approach of this very fast speed boat was announced by its roaring engine well before it came in sight.

I wasn’t interested in the details of the boat but wanted a long exposure to have a blurred trail, making the speed somehow visible to the viewer, while bridge and even background remain sharp. The darker part of the 3-stop GND filter was pushed all the way down in the filter holder to cover more of the frame, ISO 50 prolonged the exposure time a little more, and by using an aperture of f/20 I ended up with 1/4 of a second. Needless to say that the camera was on a tripod and focus was obtained manually by pre-focussing on the center of the bridge. The water in the foreground had some turbulences that were slightly blurred in the photo, making it a bit more interesting without distracting too much.

AUTUMN IN MINNESOTA #14 - WILDLIFE ENCOUNTERS IN LOW LIGHT

White-tailed Deer, Bear Head Lake State Park, Minnesota

I have never been a friend of shooting wildlife with an ISO setting above 250-320. But when you walk out into nature early in the morning or during a day with low light due to overcast, you have to rethink your ideas. The higher the ISO, the lower the resolving power, the more noise in the image, and the lower the dynamic range. But at the other hand, a sharp photo with a higher ISO setting is still better than capturing a blurry picture because shutter speed is too slow as a result of having the ISO settings in the basement. This is in particular true if a very long focal length is employed while handholding the camera. There is a limit where Vibration Reduction or Optical Stabilization, as SIGMA calls it in their lenses, may help you to get a sharp image. The well-disposed viewer of a photo on the web, in a blog post, on Instagram, or any other social site may not see much of a difference, but the real quality bar for a good photograph is the ultimate print.

The photo of this White-tailed Deer, up in Bear Head Lake State Park, Minnesota was shot at ISO 800. To make it clear, it wasn’t a difficult shot. As I wrote here in the blog before, the deer near a campground are not tame, but they are used to people and don’t run away as soon they see a human. Staying in or near a campground is a safety strategy that at least works during the camping season. Their predators, like wolves, avoid these places.

I have shot handheld at 500-600 mm focal length, 1/60 s, ISO 200 or even lower, but I also have deleted a lot of pictures with this kind of settings. Practice is always the key to success for sharp photos but sometimes a higher ISO can save your butt.

THE SOUND OF PROP PLANES

During the last couples days the sound of propeller driven airplanes over the house made me aware that it is the time of the year again when pilots with their historical planes get ready and practice for the big airshow next week in Oshkosh, Wisconsin. This evening I went out to the Dubuque Regional Airport and tried to make some clicks. I have done this before during other years and although I’m not really into aviation photography I enjoy these airplanes and take this opportunity for practice of handholding skills with the heavy long lens attached to camera. My keeper rate wasn’t very good today and I hate to come up with tons of excuses, but it was pretty much the lack of practice of my handholding capabilities.

As mentioned in other blog posts over the years before, I like to tell the story of motion with these airplanes and aim for a blurred prop. The only way to get this kind of shot is to stick with a slow shutter speed, means between 1/60 s and 1/200 s. The T6’s flew in formations of four and this was my favorite shot of this evening. But wait, there was some bird present at the observation deck of the airport that I haven’t seen in a long time. But hey, this is for another blog post… 😉

SLOW SHUTTER SPEED, STILL GOOD FOR THE STORY

Ruby-throated Hummingbird

There are many ways to make a picture of a hummingbird. Some people may like to present every single feather to the viewer and ‘nuke’ the birds with tons of flash light in order to freeze the action or obtain depth of focus. This is perfectly fine if counting every feather is important for the story, like maybe in a bird guide book. With still photography it remains a challenge to tell the story of an extremely fast moving bird and even lots of video footage I have seen doesn’t always meet the expectations. For me it is natural to have at least the wings blurred in order to tell the story of the extremely high frequencies of their wing beats. When the hummingbirds hover for parts of a second in front of a flower or a feeder their body seems to stand still and this is the moment I use for my photos. The metadata of yesterday’s shooting in our front yard show that the exposure was between 1/50 s and 1/320 s. The photo above was shot with a shutter speed of 1/125 s. Sure, the rate of keepers versus misses is not the same as shooting your coin or stamp collection, but hey, the fun is at least ten times bigger… 😉

MOTION BLUR FOR STORY TELLING

Male House Wren

How can we tell the story about the male House Wren, who sits on a perch near the nestbox and sings and chatters like crazy to impress one of the females? Knowing a little about the biology of the critter helps to answer the question. When the wren performs, he holds the upper mandible relatively still, while the lower mandible goes up and down with lightning speed. By using a relatively slow shutter speed (between 1/60 s and 1/160 s) I was able to freeze the eye and upper mandible while the lower one has a slight motion blur. We can use a real fast shutter speed and a powerful flash light to freeze every little feather on this wren, but there is a chance it may look like the wren is yawning, and this would be a totally different story we tell with our photo. A little hint of flash was used for this image to make the color of the wren’s bill stand out, but not to freeze the action.

SCARLET TANAGER AND THE AMBIENT LIGHT

The Scarlet Tanager is a very secretive bird but sometimes the males show up at our suet feeders for a brief moment. Usually they also disappear very quickly again after getting a few peanuts. It is not so difficult to make any feeder pictures but it takes a lot more to make the click while they are in the trees around our house. The thick and lush canopy of our trees here swallows up a lot of light and locking in the focus can be a challenge. As always in these kind of situations I use the speed light only for flash fill, for boosting the colors and not as my main source of light. This means to shoot with slow shutter speeds (1/60s for this photo). The ambient light plays a big role for the environmental portraits I’m aiming for in my wildlife photography and using the full power of the flash light would just not deliver the results I’m looking for. Not having every single feather of the bird tack-sharp is the small price I have no problem to pay in this matter.

“SLOW” TELLS A BETTER STORY

@500 mm, 1/40 s, f/8, ISO 500

We never had so many Ruby-throated Hummingbirds visit the yard like this year. Especially now, with the juveniles buzzing around, it is very busy at the hummingbird feeders that hang from our porch. Every second day we mix a 1.75 liter bottle of sugar water to keep up with the high demand. We never ever have even been close to this amount. 

After a number of hot and humid days we finally got some much needed rain yesterday and today and the temperatures dropped quite a bit. This is probably another reason that we saw the hummers even more frequently today. With nothing but gray clouds in the sky I decided to stay home after work and aim for some new photos of the smallest bird we have here during the summer.

I was asked today if I shoot my hummingbird pictures with a high speed setup. The answer is no, I don’t. Remember, my goal is story telling and that means in most cases I like to show a hint of the environment, even if it is just blurred because of a shallow depth of field, like with these two images from today. The light and the green and yellow color in the background suggest a lush environment, typical for a day in August, and typical for just how it is around here at the moment. On a rainy day there isn’t much light available and using the flash is essential to bring out some colors of the birds. No matter how hard I would try with a high shutter speed of, lets say 1/500 s or even faster, the background would always be pitch-black. And with that there is no story telling…

Another part of the story telling in both photos is the dynamic of the wing beats. You see the wings multiple times and this is how you see the birds when they buzz around. They don’t look frozen. However, there has to be one thing that needs to be sharp to make the image work, and that is the eye of the critter. If the eye is blurry, and believe me that happens more than I like, the image ends up in the trash can of the computer…
