Photo Gallery: Using Special Techniques


Cowboy and Cars, Badlands

Photograph by Annie Griffiths, National Geographic  
Some kinds of photography require more specialized techniques and equipment than others. Whether you want to shoot fireworks, colorful species underwater, or terrain from a low-flying aircraft, knowing your subject and preparing for the challenges it presents is critical. In this gallery, see how technique and imagination can be combined to create striking images.

Photo Tip: When shooting at night, long exposures that let cars pass all the way through the frame will give you rivers of white and red lights.

Moonrise, Chesapeake Bay

The moon rises over a building of the Chesapeake Bay Foundation in Maryland.
Photo Tip: The best time to take a picture of the moon is just as it rises, when it’s big but not too bright.

African Elephant, Botswana

Photo Tip: If you plan to shoot just after sunset, or right before sunrise, scout the location ahead of time to look for elements to silhouette against the sky. The colors can make gorgeous backdrops for all sorts of things.

Oktoberfest, Munich

Photograph by Veronika Kolev, My Shot
I took this picture at Oktoberfest, a festival held each year in Munich, Germany, from September to the first days of October. That evening the sunset was spectacular, with magic colors, and the following "blue hour" was also amazing. I was happy to visit that place and to be one of the six million tourists who attend every year!

Photo Tip: When shooting a city or similarly lit scene at night, look for the moment when the darkening sky and the ambient lights are evenly balanced, so that you get detail in both.

Evening, Los Angeles

Photo Tip: At night, there are often sources of light in the frame that can fool the meter. Bracket your exposures to be sure you have the shot you want.

Sunset, Israel

Captured in silhouette, a man leads a donkey bearing a pregnant woman in a scene reminiscent of biblical Joseph and Mary on the road to Bethlehem.
Photo Tip: Long lenses give you a big solar disk at sunset. Similarly, a telephoto will keep the moon from being a tiny white spot in the sky.

Tube Sponges, Gulf of Mexico

In the Flower Garden Banks National Marine Sanctuary in the Gulf of Mexico, steel pillars supporting a gas platform make a vertical reef encrusted with tube sponges.
Photo Tip: When photographing underwater, work within about ten feet of your subject. At greater depths, you'll need strobes for color.

Waterfall, Iceland

Dettifoss is a waterfall in Vatnajökull National Park in northeast Iceland. It’s reputed to be the most powerful waterfall in Europe.

Photo Tip: To freeze a waterfall, you need a shutter speed of at least 1/250. If you don’t have enough depth of field, try a wider lens and move closer.

Stream, North Carolina

Photograph by Amy White and Al Petteway, National Geographic
A woodland stream tumbles over moss-covered boulders in North Carolina.
Photo Tip: To blur a waterfall, try a shutter speed of 1/8 or so. Use a tripod and a release cord or the camera’s self-timer to avoid camera shake. Watch for wind blowing any trees or bushes that appear in the frame.

Fire Dancers, Bora Bora

Fire dancers illuminate the night on Bora Bora.
Photo Tip: Keep in mind that photographing at night requires long exposures, which means that people in the scene will blur easily if they move. In these situations, you may want to let the effect work for you.

Fireworks, Netherlands

Photograph by Vikas Gupta, Your Shot
This was shot on the beach at Scheveningen, Den Haag, during the International Fireworks Festival, an annual competition. Participants have included Belgium, the Netherlands, Germany, Canada, Brazil, China, Japan, and the city hall of Den Haag.

Photo Tip: Reflections in water will make your images of fireworks even more dramatic.

Tuareg, Sahara

Before setting forth on a 270-mile trip to Bilma in Niger, Tuareg tribesman Mahmouda Mahamoudane and his ten-year-old son, Adam, sit before a fire on the sands of the Sahara. Dromedary camels rest in the background.
Photo Tip: If you plan to photograph people around a fire, try to shoot at dusk, when there’s still a little bit of light.

Moon and Landscape, California

Photograph by Peter Essick, National Geographic
A setting moon makes a fitting backdrop for a lunarlike landscape near Donohue Pass in California’s Ansel Adams Wilderness area.
Photo Tip: Black-and-white photography allows the photographer to present an impressionistic glimpse of reality that depends more on elements such as composition, contrast, tone, texture, and pattern.

Portrait, Thailand

Photograph by Drussawin Leepaisal, My Shot
I found this woman waiting for her husband after finishing her work. Her eyes are very interesting to me.

Photo Tip: When making black-and-white images, shoot raw files instead of JPEG (if your camera allows it) so you don’t drop the detailed information you’ll need to process images as you like on the computer.

Volkswagen, Rio de Janeiro

Photo Tip: Shoot black-and-white photographs with the lowest ISO possible to decrease the amount of noise in the darker tones.

Wine Cup Flower, South Africa

Photo Tip: When making macro photographs, check your background to be sure that it sets off the subject and is free of distracting objects. If you don’t like what you see, slip a piece of colored paper behind the subject. With the shallow depth of field, your subject will be sharp and the background muted.

Reflecting Pool, Lincoln Memorial

Photograph by Robin Moore, My Shot
In this image taken using an infrared filter, a visitor takes a picture of the Lincoln Memorial from the edge of the Reflecting Pool in Washington, D.C.
(This photo was submitted to My Shot.)
Photo Tip: When using an infrared filter, long exposure times and a tripod are needed, and focusing will be difficult. You never know how an infrared image will come out, so be ready to experiment.

Buena Vista Grasslands, Wisconsin

Photograph by Shane Rucker, Your Shot
In this infrared image, trees are shown in the Buena Vista Grasslands in Portage County, Wisconsin.
(This photo was submitted to Your Shot.)
Photo Tip: Ideal shooting conditions for infrared photography are often the exact opposite of those for visible-light photography. The best results are often found at midday, in strong sunlight. To remove the red cast present in color infrared images, convert them to black and white on the computer.

Desert Dunes, Namibia

Photograph by Frans Lanting, National Geographic
Over thousands of years winds have sculpted sand in the Namib Desert into some of the world's tallest dunes, colored red by iron oxide. The sand contains just enough moisture to sustain a few hardy plants. Not far from this dune, one called Big Daddy looms 1,200 feet above the desert floor.
Photo Tip: Patterns are especially revealing from the air, whether they are the rectangles of agricultural fields or the symmetry of sand dunes.

Lençóis Maranhenses Park, Brazil

Photograph by George Steinmetz, National Geographic
Water dark with tannin inspired the name Rio Negro, or "black river," which swirls across virgin sand in Lençóis Maranhenses National Park. In the park's ponds, thriving communities of algae can turn the water blue or green.
Photo Tip: Aerials can be tricky because you’re moving when you shoot them, so use a shutter speed of 1/250 or faster.

Tulips, Tasmania

Photograph by Anthony Crehan, Your Shot
Aerial view from a helicopter of the tulip field at the Table Cape Tulip Farm on Table Cape, near Wynyard, on the North West Coast of Tasmania. It was Blooming Tulips Festival Day at Wynyard and fortunately for me and my six-year-old grandson, the helicopter operator was selling 15-minute joy flights. On the left-hand end of the rows of tulips, you can see some of the visitors to the farm.

Photo Tip: When making aerial photographs, fly in the morning if you can. The air is not only clearer then but also often less bumpy.

Sunrise, Joshua Tree National Park

Photo Tip: When making HDR images, don’t eliminate shadows—they lend definition and depth to a picture.

The Tube, London

Photograph by Bruce Benedict, My Shot
My wife is an ex-Londoner, so I follow her around when we travel. Often I have no real idea of where we are, but I snap away and struggle to keep up! This is from a trip last summer.
(This photo and caption were submitted to My Shot.)
Photo Tip: HDR techniques combined with other digital manipulations can be pushed to achieve a hyperrealistic effect.

Pío XI Glacier, Patagonia

Photograph by Maria Stenzel, National Geographic
A 46-foot steel yawl is anchored before the face of Pío XI Glacier, Bernardo O'Higgins National Park, Patagonia, Chile.
Photo Tip: When making panoramic photographs, consistency is the key—consistency of perspective, exposure, and white balance. Don’t move or zoom in or out between shots. Keep the whole image in mind.
