There have been more than a few days when I’ve wondered if I travel to do photography or if the camera is just an excuse to get outside amidst inspiring landscapes. Actually, there is no wondering about it. It’s the latter. I have a deep, soulful connection to nature. Truth be told, if faced with the choice of spending my remaining years alone in a magnificent wilderness or amongst the beehive of activity in a major city, I might choose the wild.

It should come as no surprise, then, that landscape imaging is my first love in photographry. Since a move from the Midwest to northern Arizona nearly 20 years ago, I’ve been blessed to have ready access to some of the most dramatic and iconic landscapes of the American West. Grand Canyon, Monument Valley,  Arches, Canyonlands – these are nature’s cathedrals. These are the places where I hone my craft and renew a spiritual connection with the world.

This blog continues the series in which I share the camera settings I use for specific genres of photography. Today’s genre is landscapes and these are the settings:

  • Mode: Aperture Priority
  • Aperture:  f/13 to f/22
  • ISO: 100 to 200
  • Image Format: RAW
  • Focus: Back Button or Live View
  • Shutter Release: Timed with a 5-second delay
  • Essential Gear: Tripod

Great light is the first element of a great landscape. While it is absolutely possible to make a fantastic landscape exposure in midday light, the golden hour times of sunrise and sunset are the most prized. The soft earthy glow adds a dramatic feel and reveals the inner beauty of a place. Weather, is the second key element. Clouds, rain and lightning put passion on display. Snow reveals the essence of a place and hints at possibilities to come.

A common theme connecting the above, is the relatively low light levels one encounters when shooting under such conditions. Unlike other genres (e.g. sports, wildlife and portraiture), short exposures and shallow depths of field are not necessarily desirable when shooting landscapes. More typically, you want great depth of field. Also, since your subject is mostly static, exposure times can be longer without compromising image sharpness.

An f/13 to f/22 aperture will deliver an in-focus, sharp image through the fore-, mid- and backgrounds. (APS-C bodies can achieve the same at f/9 to f/16.) With depth of field being so critical to achieving the desired result, I usually shoot in Aperture Priority mode and dial in an aperture – more accurately, a focal ratio – of f/13. Depending on the lighting and composition, I’ll go as large (in focal ratio) as f/22 or more.

Of course, I always shoot in RAW to allow as much latitude as possible during processing.

To maximize image quality and minimize noise, I typically use the base ISO of the camera body. In the case of the Nikon D610, the base ISO is 100. This combination of low light, small aperture and low ISO forces the camera to use relatively slow shutter speeds to make a properly exposed image. When shooting just before sunrise or shortly after sunset, an exposure of 1-second or longer may be needed.

Long exposures demand a solid, stable platform to ensure good sharpness in the resulting image. This makes a tripod essential gear for the landscape photographer. I use a Benro model tripod. It is designed to be lightweight and portable, while still providing good stability. It is not as rock solid as other beefier designs, which means I’m always in need of a sheltered location when doing photography in a strong wind.

A technique I use to minimize vibration, is setting a 5-second delay on the shutter release. This allows any vibration introduced when I push the shutter release to dampen before the exposure begins. I also use either back button focus or contrast detection focus in Live View to help ensure best focus. Contrast detection, while slower, is sometimes a bit more accurate than phase detection. Moving focus control off the shutter release button minimizes the risk of a last second focus change when an exposure is made.

Using these settings, allows me to take full advantage of the spectacular landscapes populating the Desert  Southwest. If you are a landscape enthusiast, I hope you find they help your results, as well.

So, get out there and shoot.

A, Is for Aperture Priority

I don’t recall exactly how long it took before I was able to look at the letters on the menu dial of my camera and see anything other than alphabet soup. It certainly wasn’t overnight after first getting the camera, weeks at a minimum but probably closer to months.

In part this was due to the ability of the modern DSLR camera to auto select settings that produce good photos. Another factor was the menu of scene modes on my Nikon D70. When taking pictures of people, I used the Portrait setting. I also used the Landscape, Sports and Night settings. The names said everything I needed to know about their function and made it easy to explore settings other than Auto. Yes, I was getting all radical with my camera and trying different menu dial positions just weeks after getting it.

But the real experimentation started when I took the leap of faith required to dive into the alphabet soup settings on the menu dial: A, M, P and S. In addition to being an anagram for, spam, those four letters tease and temp a new photographer with hints of the unknown and mysterious. What happens when you choose, A? Will the camera even function?

A, is for Aperture Priority, a setting where you manually select the aperture and the camera fill in the other settings. An aperture is an opening that allows light to pass through the lens and fall on your camera’s sensor. If you’re framing a shot at high noon on a sunny day, there’s a lot of light hitting your subject. This abundance of ambient light means your camera’s aperture can be small and still allow enough light to hit the sensor to capture a beautiful image with a short exposure. This brings us to the concept of f-stop or f/ratio. These terms mean the same thing, the ratio of the focal length of your camera lens to the diameter of the lens opening (aperture) allowing light to fall on the camera sensor.

Suppose your shooting with the kit zoom lens that came with your camera and the focal length (zoom) is set to 50 mm (millimeters). Put the camera in auto and take a picture of something. Then, play the photo and look at the information about that exposure. In particular look for the f-number. The number next the f tells you the ratio of the aperture to lens focal length. A picture taken with a 50 mm lens at f/10 had a 5 mm (1/5-inch) aperture. A picture taken with a 50 mm lens at f/4 had a 12.5 mm (1/2-inch) aperture or opening.

So, the smaller the focal ratio or f-number, the larger the aperture. In short, when you shoot with a small f-number, you’re letting more light into the camera to fall on the sensor. Or at least, your camera is trying to let in more light. When we started this discussion, we began by imagining a scenario of taking a picture at high noon on a sunny day. Let’s change the time from high noon to the golden hour, that first hour after sunrise or last hour before sunset when natural light is soft, warm and dramatic. The light quality is better but there’s not as much of it. So, in order for your camera to allow the same quantity of light on its sensor as a shot taken at noon, the aperture needs to be larger.

The begs the question, so what? Why should you care that the aperture needs to be bigger during the golden hour than at high noon? Well, aperture determines the depth of field in a photo. Depth of field is the range of distance within which objects or people will be in focus in a photograph. When shooting portraits, it’s often more pleasing to have a shallow depth of field. In other words, the person who’s the subject of the photo is in focus but anything in the foreground or background will be out of focus. This quality of an out of focus foreground or background is called, bokeh. Bokeh is a Japanese term describing the portion of a photograph that is obviously out of focus. When shooting a portrait, obvious bokeh in the background is typically very pleasing to the eye. The way to create bokeh in your shot is to shoot using a small focal ratio or f-number, the smaller the better.

Above, is an example of bokeh. The subject is in focus in the foreground and the background is obviously out of focus. This transforms the background flowers into a pleasingly abstract tapestry of hues and textures complimenting the subject of the photo.

Suppose you’re shooting a landscape at sunset. A wonderful, warm light is painting the temples and buttes of Grand Canyon. For this shot, you’ll probably want everything in your frame to be in focus. You’re not trying to capture just one temple or butte. Everything in your frame needs to be in focus. In this scenario, a shallow depth of field will put much of the frame out of focus. To put everything from the most distant butte to the blooming foreground wildflower in focus, you need to shoot using a large focal ratio. Typically, I shoot at f/9 when doing landscape photography.

This photo of Desert View Watchtower on the South Rim of Grand Canyon was taken at sunset. My Nikon D90 was mounted on a tripod. The camera was in aperture priority at f/9, ISO 500, a lens focal length of 19 mm and an exposure of 1/30-second.

This brings us to the final question of this blog entry. What impact, other than depth of field, will shooting at f/9 have on your photo? As we’ve discussed, the larger the f-number the smaller the aperture or lens opening. If shooting at sunset to capture a landscape illuminated by that gorgeous, soft light, you can compensate for the small aperture by boosting the ISO setting. The same scene that can be captured with an ISO of 200 at high noon, may require an ISO setting of 800 during that dusky time around sunset.

But there is a price to pay for taking this approach. Boosting the ISO to make your camera more sensitive to light adds digital noise to your photo. With higher end digital cameras, images shot at ISO 800 often look very good. But if you’re shooting with an entry-level camera or an older DSLR, an image shot at ISO 800 will often looking grainy and rough. Rest assured, however, there is another solution.

Use a tripod. For landscape photography or any photography where you want to capture sharp, detailed images with good depth-of-field, a tripod is essential gear. Mounting your camera on a tripod allows you to precisely frame the shot. It also allows you to shoot at low ISO’s of 400 or less during the golden hour and still capture great detail. The scene that was perfectly captured with a 1/500-second expose in bright sunlight may require a 1/10-second exposure at a time of day when the quality of the light is warmer, softer and more dramatic.

Now, 1/10-second may not seem slow but trust me, it is slow in photography. As a general rule when shooting handheld, you want exposure times to be no slower than the reciprocal of the lens focal length. OK, in English. Let’s say you’re shooting with a 50 mm lens. If you’re holding the camera in hand for the shot, the slowest shutter speed you’ll want to use is 1/50-second. Faster would be better. Any slower speed will allow the camera to capture the vibration or unsteadiness of your handhold. That vibration will soften details and produce an image that looks out of focus. If the camera is mounted on a tripod, that rock solid platform will allow you to take longer exposures producing crisp, focused photographs.

OK, I’ve rambled long enough. The next time you’re out with your camera, experiment with using the A or aperture priority setting. Shoot the same subject using different apertures. Compare the ISO settings and exposure times for the resulting photos. Most important, compare how the photos look. Which one looks best to you? Write down or make a mental note of those settings and spend the rest of the day shooting with them. You’ll learn a little more about your camera and you’ll get some great shots.

Get out and shoot!
