It was interesting photographing the Aurora Borealis for the first time. We arrived around 8:30 pm and left a little before 1 am. I always find it a balance between pure excitement of creating amazing photographs and life commitments. So, I did my research, but quickly realized that it was only a starting point to get a picture. The results of my experience unfolds below. . .

The photo above is the sunset before the show. I thought is was interesting to see the halos around the sun as it was setting. I took this like any sunset. I noticed the halo and soft appearance of the sun once I got home and looked at it on the computer. Truly, it was the perfect beginning of an evening photographing the Aurora Borealis.

This is my very first attempt at photographing the Aurora Borealis. I followed the instructions from online, and this was the result. I placed my Canon 5D Mk II with Sigma 24-105 Art Lens on my tripod. I adjusted it so the horizon was straight. I used the following exposure: ISO 1250, f4, 8 sec. I set my focus manually to infinity. Afterwards, I did some exposure adjustments in the digital darkroom, and this was the end result. I think it’s pretty good for the first time.

As I thought about the location, exposure, and composition elements, I realized that I needed to experiment with the exposure. I usually try to use lower ISO so I do less post-processing to reduce noise and pixelization. If it can be done in the camera, why should I spend time on the computer trying to “fix” it?

Finally, the show revved up! The whole sky filled with color and movement. I wanted to show it all, so I pulled out my Canon 8-15mm lens. The image above is taken at 8mm (fish-eye), and captured the entire scene. I like the people, buildings and lights around the edge. It gives it a sense of place, and shows the life of the event. People cheered as the Aurora shifted and showed its colors. At this point, I changed my exposure and approach to photographing the aurora. My camera was still mounted on my tripod. My exposure was ISO 400, f4, and 10 sec. I worked with fine tuning the exposure and color afterwards in the digital darkroom.

I think the biggest thing I learned about this event is to be open to experimenting with exposure and composition. Often, we are in a place or situation less than ideal for our vision. It is good to be adaptable and open to the opportunities available. What knowledge I can offer is simply. . .you need a tripod to get crisp, clean photos of the aurora or other night photography. The rest is up to your knowledge of your equipment and exposure.

Creating a Photographic Story

A photograph is the reflection of the photographer at the time the image is created. It reflects our mood, vision, and emotional state. The way the light is captured in the image, then post processed reveals the story hidden in the photograph. It is a visual communication between the photographer and their audience.

The image above was take this spring during the afternoon (during a short day escape during the Pandemic). The weather report called for rain, yet it hadn’t rained yet. The clouds were amazing and dynamic. The hillside viewpoint allowed me to include the Columbia River, Vantage, I-90, and the dynamic clouds. I brought more contrast into the post processing. I like how it look a ominous.

In the next image, I took a different approach. . .

What attracted my attention in this image is the dynamic clouds, the lines of the hillside, and the wild horse monument. I return to this place at least once a year to experience the high desert changes. I love the changing sky. Often this area is a treasure trove of opportunities to explore line, shape, textures, and other compositional elements. It usually isn’t over-run with people, and the hike to the top is relatively easy.

The biggest piece in creating a photographic story is the photographer’s vision or ability to compose in the field. It is the culmination of an idea, and the cooperation of the weather/other elements in the environment. The subject or important element needs to fill the frame. The following photograph focuses on the amazing cloud formations.

The clouds are far more interesting than the landscape, yet what sits on the horizon? This is looking west towards the Cascade Mountains, and the clouds have created a dark blue-gray background for the turbines in the distance. A small airplane sits in the sky against the background of the massive clouds. Both the turbines and airplane give some perspective on the size of these cloud formations.

Exposure for these images is important and contributes to the story. All three are shot with at F16 or F22. This is a large depth of field, and gives the viewer a visual reference to the fore-ground, mid-ground, and background. A larger depth of field gives an expansive feeling to the photographs, and contributes to the 3D feeling in the images. A shallower depth of field would give less visual information to the viewer, and feel more 2 dimensional.

Through all these social challenges we face today, may everyone stay well and continue to photograph the world around us.

Backgrounds & Choices

The combination of background and available light affects the outcome of a photograph. Birds are adept at camouflage, and our cameras are great at hiding the subject. The photo above is a corn field and 7 sandhill cranes. The coloration of the cranes allows them to blend into the remaining brown corn stalks, and almost disappear.

The late afternoon lighting leaves long shadows for these cranes to blend into the field.

In this photo of the trumpeter swans, the dark background helps the swans stand-out as the subject of the image. The swans are in shade (similar to the crane photo above), and their coloring allows them to be easily differentiated from the trees in the background.

Both of these images are taken with a 600 mm lens, yet the ease of see the subject is dependent on the background and exposure. Both are shot at F8. The difference is the location of the birds with the background. The cranes are in the field. The swans are flying past the trees.

032517-KLU-9042

This last photo has the simplest background. The solid blue sky offers a background to easily see the subject, 2 sandhill cranes in flight.

Background choices can help or hinder the success of a photograph. Ultimately, it is dependent on opportunity, exposure, and choices made by the photographer.

Tip – Use backgrounds for your subjects that help convey the vision of the photograph.

Choices, Exposure & Composition

The experience included hundreds of sandhill cranes flying overhead, with some landing in the field below. Their sounds waft in the air, like a light trill. Unlike ducks and geese, the cranes seem to fly without formation, and their flight is affected by wind gusts.

At a distance, it becomes easy to place hundreds of these amazing birds into a single frame. The photo above is taken with a 600 mm lens. The challenge becomes “how are the birds placed in the frame?”

032418-KLU-3263e

One thing to remember is that these birds are not small. There size ranges from 3 to 5 feet tall (depending on sub-species and male/female), and their wing span ranges from 5 to 7 feet across.

The photo above is a grouping of 3 birds against the sky. Light is important in all photography, and especially important when photographing birds. The light in this image is late afternoon sun, and it casts a warm glow in these cranes. It is important to light up the head (or face) of the bird.

032418-KLU-3325e

In this photo, the light brings the cranes out from the blue background. Without the sunlight, the birds would blend into the background, and be more difficult to see. As for where to focus. it is good to select an area with a large concentration of birds. It is easier for the camera’s auto-focus to actually focus on the subject.

As for exposure, expose for the birds. The background isn’t as important as the cranes, and it’s okay for it to go light or dark. The shutter speed needs to be fast enough (1/250 sec or faster) to keep the cranes from blurring. At a distance, an aperture of F8 should offer enough depth of field to keep most of the birds is focus.

Tip – Use the available light. Set the shutter speed to stop the action, and the aperture to keep most of the flock in focus.

Focus. . .

by karenulvestad, posted in Tips

Focus is a key to a successful photograph! I mean focus on the subject and the idea behind the image. What message is the photographer trying to convey through the visual medium of photography.

Beyond technique, a great photograph shares a story. Otherwise, why would we want to look at it, share it, have it in our homes (or office), or purchase it?

The message could be peace and tranquility. It may show the chaos of the inner city. What is it that drives the interest in the photograph? What is it’s story?

As photographers, we can all take beautiful photographs. The digital age make accessibility to quality equipment available to a wider range of people. There are so many choices – phones, point and shoots, mirrorless, or DSLR.

So, what story do you wish to tell? It is a question to ask yourself as you compose your photographs.

Happy Shooting. . .Karen

 

Digital Photography Basics Excerpt. . .

“Ambient light is the naturally available light. Sources would be the sun, moon, or reflected light. Sunlight is the light source even on cloudy days or in the shade. Cloud cover offers soft, diffused light without harsh shadows or contrast. Ambient light can be dramatic like the previous photo, or soft like the photo to the left. Dramatic lighting often requires a wide range in tonal quality in the image. The previous photo was exposed for the light rays coming through the clouds.” ( for complete book excerpt  dpb-exp-comp-pg7 )

Photo Walks Are A Hands-on Way To Learn Photography

by karenulvestad, posted in Location, Workshops

copyright Karen Ulvestad

Sunsets and Photo Walks seem to go together. It is a great way to learn exposure, while photographing a sunset. Exposure affects the colors in the sunset, whether or not a foreground object becomes a silhouette, or simply how to prevent the flash from going off. It’s helpful to have a knowledgeable photography instructor to help hone these skills.copyright Karen Ulvestad

 

 

The Edmonds waterfront is a great place to see the sunset, and experience a photo walk. There is a great abundance of subjects to photograph, including the ferry boats, sail boats, gulls, bald eagles, harbor seals, and more.

I would love to see you at my next photo walk on August 25th, 2016. Sign up is through the City of Edmonds at http://www.reczone.org.

Shadows, Highlights & Mid-tones

by karenulvestad, posted in Instruction

copyright Karen Ulvestad

So, I’ve been missing in action the past few months, and neglected my blog!

I’m back. . .at least until my next adventure that leads me away from the computer screen and the Internet.

I’ve been pursuing the Light. Without light, there cannot be a photograph. Light is a challenging subject, because our eyes see it one way, and our camera sees it in a different way. Our eyes can see the details in the brights (highlights) and darks (shadows) on the brightest sunny day. Our camera cannot.

copyright Karen Ulvestad

Technically, this means the difference between shadow and highlight is greater than 2-stops of light. So, what does a photographer do?

One to compensate for this difference in lighting is to use the HDR setting in the camera, or a software program on the computer. The HDR setting on the camera will take 3 exposures (1 for the shadows, 1 for the highlights, and one for the mid-tones), and combine the 3 into one photograph. Computer programs work with highlight, shadow, and mid-tone settings within the photograph to accomplish a similar effect.
