Golden hour at the Tallgrass Prairie National Preserve

My October visit to the Tallgrass Prairie National Preserve in the Flint Hills of Kansas did not disappoint. The prairie was ablaze in the colors of fall and some of the early dawn skies were spectacular displays of clouds and sky that appeared to be on fire; reminiscent of the flames of the nighttime prescribed burning of the prairie I witnessed in April.

These pre-sunrise displays of color are often referred to by photographers as the golden or magic hour. It’s really not an hour per say and the golden hour also refers to the evening sky just after the sun has set. The moment of optimum color can be a fleeting few seconds or it can last for hours. The key is that if the sun is visible on the horizon in the morning, chances are you have missed the best display and if the sun is still on the horizon in the evening, the best is yet to come. The early dawn photos of the Lower Fox Creek School at the Tallgrass Prairie National Preserve are a prime example.

Anyone who studies the photos of National Geographic photographers will see that many of their outdoor photographs are taken in the very early morning hours and in the fading light of the early evening. National Geographic photographers know this and plan their day accordingly, shooting interiors, traveling, etc. during midday.

Spectacular pre-dawn photos come at a price — sleep. If you’re not hiking to your location in the dark (and by dark, I mean having to use headlamps), chances are you’re going to miss the magic light. If the sun is already above the horizon, you might as well go back to bed. On countless mornings I have had to force myself out of the warmth and comfort of my sleeping bag to head out in the darkness and on countless evenings have had to return to camp to make dinner in the dark. On a few occasions when I was car camping I would have to move the entrance barrier to the campground to exit in those early hours. Neighboring campers would wonder if I even existed as I was never seen.

A lot of photography is about luck, and by luck I don’t mean just being lucky. You need to make your luck. Research is probably the most important secret to a good photograph. Knowing when, where, and why will always increase your luck. It’s like buying a thousand lottery tickets instead of just one. To help make my luck I use several iPhone and computer apps that will show me precisely where and when the sun and moon will rise and set, their position through the day for shadows, where the Milky Way will be, and what approaching cloud cover (or lack of) will be. I’ll even use 3D mapping programs with satellite imaging to give me a feel for what I might see.

If you look at the photos in the slideshow, you’ll notice that many of the images might seem redundant. As a stock image photographer, I need to keep the needs of a designer in mind. For example, there are multiple images of the Lower Fox Creek School silhouetted in the pre-dawn light. No, it’s not a case of I can’t make up my mind which photo I like better, but rather there are multiple images to give designers choices. Would a page design work better with the school on the left, or the right? In addition, I’ve left plenty of space for story or cover text. I’ve also included vertical and horizontal options. These examples of shooting with possible design usage in mind are all things that I looked for when I was a magazine art director/designer and bought usage licenses. Here again, I’m making luck that hopefully will result in a licensing sale.

The tallgrass prairie in the Flint Hills takes on a whole new personality in the fall. Grasses and wildflowers turn brown and red after the first chill of fall and the incessant frantic calling of dickcissels are replaced with the quieter chirps of crickets. It’s like the prairie knows that it is time to rest. The tallgrass prairie simply feels calm and quiet, just like the drowsiness a person feels just before falling to sleep. I’m looking forward to traveling back to the Flint Hills in the weeks ahead to walk the sleeping prairie as it is blanketed in snow.

Bald Eagle Number 88 – tagged for airport eviction research

Bald eagle number 88, Alaska Chilkat Bald Eagle Preserve

iPhone photo field report: Over a three year period, I have talked about a leucistic, white-tipped bald eagle, that I have watched and it is always interesting to see where this eagle shows up. A few days ago, I spotted another special bald eagle while on the Chilkat River in the Alaska Chilkat Bald Eagle Preserve near Haines, Alaska. In this case, the eagle is easily identifiable by a large numbered green badge that is attached with a rivet-like coupling to its wing.

According to the Takshanuk Watershed Council website bald eagle Number 88 was originally tagged by the U.S. Fish and Wildlife Service in Juneau, Alaska (roughly 95 miles away) as part of a study examining the effects of nest removal at the Juneau airport. Steve Lewis, of the U.S. Fish and Wildlife Service, was quoted as saying that Number 88 was a control bird matched with a pair of eagles that were nesting near the pond airstrip where float planes land and take off. The eagle originally had a GPS tracking pack but lost it this summer.

Like the leucistic bald eagle, it will be interesting to see where Number 88 shows up in the years to come. Knowing that you are seeing the exact same bird year after year is like seeing an old friend.

For those interested, I spotted bald eagle Number 88 at 11:33 a.m. AST on Nov. 17, 2011 in the Alaska Chilkat Bald Eagle Preserve on Chilkat River near Haines, Alaska. My GPS coordinates were Latitude N59° 23.149′, Longitude W135° 51.030′, when I took the photo with my Nikon 600 mm f/4 lens. (EDITORS NOTE — Post updated with with correct time and coordinates.)

My office when photographing bald eagles on the Chilkat River

"Office" 2, Chilkat River, Alaska

iPhone photo field report: Here’s a closeup peek of my “office” when photographing bald eagles on the Chilkat River in the Alaska Chilkat Bald Eagle Preserve in southeast Alaska.

Most of my bald eagle photography is with my Nikon 600mm f/4 lens on a Nikon D3 body which are mounted on a heavy duty tripod and Wimberly tripod head. Both the camera and lens are protected from the elements with a ThinkTank Hydrophobia rain cover. I keep the cover on the lens at all times so I don’t have to fool with putting it on should it start to rain or snow.

I have the rest of my other lenses, Pocket Wizards, tele-extender, strobes, audio recorder, and video equipment in my Kiboko camera backpack bag made by Gura Gear. Also pictured is a Thermarest sleeping pad. The pad isn’t for sleeping but rather to protect my butt and feet from the cold.

Finally, most important of all, I have my lunch, usually a sandwich with cookies or english muffins from my Haines friends Joanne & Phyllis. Yum.

The photo below is the “office” view from the spot above with Four Winds Mountain in the background.

Video sampler from the Alaska Chilkat Bald Eagle Preserve




Since I didn’t go out on the river today due to the blizzard, I played around editing some of the video that I have been shooting on my Nikon D7000. It’s by no means finished — it’s basically raw footage. Eventually, I hope to take all the video that I shot and make it into something more polished. In the meantime, I thought you might enjoy some snippets of just a few places to give you a feel for where I am. There’s no sound as I don’t have a way to edit the soundtrack on the iPad. The little editing I did was done on the iPad using iMovie.

I’m new to shooting video with a DSLR. Main lessons learned so far is that I need to use a bubble level and I need to use my bigger tripod when shooting video. I’m really digging my Singh-Ray Variable ND filter for controlling exposure when shooting video. It makes it much easier.

Even more snow!

Fort Seward blizzard, Haines, Alaska

iPhone photo field report: I’ll probably stay in today. I went out to the car this morning and the 18 inches of additional NEW snow was up to my mid thigh (it’s drifting a lot with the high winds). I shoveled for a couple of hours and you would hardly know that I did. I’m guessing it is snowing at least 2 inches an hour (and it has been snowing all night). The main problem today is that the gusting winds (around 45 mph) are causing major snow drifts.

You would think school would get cancelled but that’s not the case. My young Alaska friend Gable (a middle school student) looked at me weird when I said schools back in Missouri would be cancelled for weeks with a snowfall like this one. Snow like this isn’t that big of a deal here. The photo above is from the Alaska Guardhouse where I am staying on the historic Fort Seward grounds in Haines. The building in the background is one of the old army barracks. Hopefully, the snow plow will come by soon.

iPhone photo field report: I simply love the snow that has been falling in the Alaska. Last year, there wasn’t any snow during my time on the Chilkat River photographing the bald eagles. I had hoped for snow, but didn’t get any. This year, I got my wish in a big way (see previous iPhone Photo Field Report “Don’t complain the next time it snows”). This photo, taken around noontime, is indicative of how low the sun is on the horizon during the winter in Alaska.


Don’t complain the next time it snows

Snow drift against window, Alaska Guardhouse

iPhone photo field report: When I worked at the News-Leader in Springfield Mo. the paper ran a huge front page story about an 18 or 21″ snowfall (can’t remember exactly). The headline in huge type simply said “Buried”. Well, this view (photo above) out the kitchen window of where I am staying really brings new meaning to what constitutes “Buried.” I was scheduled to go out this morning with researchers who count the number of bald eagles on the river but that got cancelled with all the snow that has been falling. Supposedly, some of the areas where we needed to go have received over three feet of snow. Given that it has been snowing very hard for the past 24 hours, I’m not surprised. I’m glad that my friend Phyllis gave me some pointers on the use of snowshoes. I’m going to use them.

UPDATE: According to a posting on the Takshanuk Watershed Council website, the total snowfall for Haines, Alaska from Nov. 1 to Nov. 23 (which was most of the time I was there photographing bald eagles on the Chilkat River) was a whopping 88 inches of snow!


The presence of grizzly bears is always a good omen

iPhone photo field report: Like baseball players, I’m a bit superstitious. In my case, when I see grizzly bear tracks, I know that the photography for the rest of the day will be great. Today I saw lots of fresh grizzly bear tracks in the new snow (iPhone photo above). It was a great day of shooting on the Chilkat River in Alaska. Weather was pretty nice too — sunny and cold with little wind (iPhone photo below).

Endless view of mountains makes you wonder

Coastal mountains sunrise from air 1

iPhone photo field report: When you see several hours worth of endless coastal mountains when flying from Seattle to Juneau, you have to wonder how many of these mountains have felt the footsteps of a human being.

When I first published this image on the Dengler Images Facebook page, some folks commented that they wish they were along with me. Little did they know that less than 24 hours later after taking this photo, I would be sitting in the dark in my car during a howling blizzard as I waited to board the Alaska Marine Highway System ferry for the 4.5 hour trip to Juneau.

I try to blog as frequently as possible on my trips (assuming I have internet access).

A bald eagle friend returns

I’m excited to hear that the bald eagles are in the process of returning to the Chilkat River in Alaska. The Haines High School Citizen Science Class (sponsored by the Takshanuk Watershed Council) conducts a count of bald eagles in the fall. On October 24, students counted 1,264 bald eagles on the Chilkat River. I’m particularly excited to hear that they have spotted the leucistic bald eagle with the white wing tips and white talons that I had photographed several years ago on the Chilkoot River. This year it was spotted at mile 15.5 on the nearby Chilkat River. I hope to see this bald eagle along with others in the coming weeks on my upcoming trip to Alaska. The SGF-STL-SEA-JNU-HNS trip — 2,600 miles by air plus 4.5 hours by ship will take three days but the travel time is always worth the effort. I can’t wait!
