Making great fall foliage images: surprising tips for success

John Heinz National Wildlife Refuge at Tinicum impoundment pond in fall.

Too often when photographers think about fall foliage photographs, they're guilty of target fixation.

They're only thinking of photographing fall foliage colors in rolling hills, vast fields and grasslands, solely in rural areas or parks, in bright sunlight and blue skies. While no one can deny that fall foliage images in those areas and conditions can be magnificent, there are many other locations and conditions than can produce equally or even richer photographs of fall foliage.

As autumn leaves change color and slowly fall, photographers need to expand their vision to the wide variety of photographic opportunities that are available to them. Scenes that include ponds or lakes like my image above, that include reflections of the green red, yellow and orange colors in the water can greatly enhance the fall seasonal feeling we look to obtain in fall foliage photographs.

Other opportunities to create these images with their intense colors can be found in rain and morning mists and fog, in urban areas, town centers, small villages, farms and in both landscapes and close-ups. Fall foliage photographic opportunities are virtually everywhere we find deciduous trees, trees that shed their leaves annually.

What is takes to make great garden photos when traveling

Garden of Eden Botanical Garden, Maui, HawaiiGarden tourism draws millions, across the world each year. Australia's National Botanic Gardens attract 400,000 visitors per year while Britain's gardens attract more than 16 million garden enthusiasts every year. In the U.S., Longwood Gardens, in the suburbs of Philadelphia, welcomes more than a million visitors each year.

Most every garden visitor can be seen documenting their visit with a cellphone, point and shoot camera, or DSLR. Some take their garden photography very seriously, using high end cameras, multiple lenses, tripods and other photography gear.

If you're interested in improving your garden photos, I've have some tips for you, about equipment, lighting, expanding and contracting your “field of view,” choosing when to shoot and three specific hints.

What makes a photograph great?

At the 9-11 Memorial, New York City, Stephen P. Russell
It seems to never fail, that in an exhibition of photographs, there are always one or two which stand out from the rest. Even though decisions are mostly subjective about how great an image is, most people zero into the same few images they consider great.

Invariably it's not one or two characteristics of an image that make it great, but a host of them, and how they work together. Contrary to popular belief, the qualities which make a great photograph aren't a secret of professional photographers and editors. Anyone who thinks about it, can figure it out.

Understanding and Achieving Image Focus and Sharpness: Part IV

Nikon 51 point Autofocus System layout in the Nikon D4 DSLR, photo courtesy of Nikon CorporationImage sharpness depends on multiple factors including focus.
While it's true an image can't be sharp unless the subject is in focus, the converse is not necessarily true, that an image which is in focus, will necessarily be sharp. Image sharpness is fundamentally controlled by focus, but there are other important factors which enable in-focus images to be sharp.

In Part I we looked at how modern digital cameras autofocus (AF), and what factors influence AF systems' ability to focus quickly and accurately.

In Part II, we discussed choosing the best focus mode for a particular subject, manual or autofocus, or using them together, as well as single versus continuous focus, all to achieve a solid focus for a variety of situations common to travel photographers.

In Part III, we got to the nitty-gritty of using autofocus and manual focus, including looking at the different AF area and tracking modes, and focus locking methods.

In Part IV, below, we discuss photographer focus technique, and other factors which enable photographers to make sharp images.

Travel portraits: family, friends, and interesting subjects

In front of Old Christ Church, Philadelphia, PAWhen traveling with friends and family, most travelers eventually want to get a nice travel portrait or two. Travelers often try to capture interesting portraits of a local inhabitants.

Sometimes the friend/family exposure is dictated by where and when you're there. Sometimes the “choice” of background and light is made, in part, to keep a famous background in the photo, to say, “We were there.”

Sometimes you can choose the time of day your photographing, the background, and the way your traveling companions are facing, thereby control how light illuminates your subjects but more often, locations and schedules dictate exposure details.

The place and time for portraits of local inhabitants is rarely in the traveler's control, but the photographer can often control their position to help set up the portrait.

Snapshots versus Photographs — Taking versus Making Images

The Great Sphinx of Giza in the foreground with the Pyramid of Khafre in the background at the Giza Necropololis. Note the prominent display of casing stones at the apex of the Pyramid of Khafre.Periodically I receive emails from travelers who compare travel photographs made by me and other professionals, with their own, taken in the exact same place, why theirs look so different from the professional shots.

They typically send me an example of their photography, although, invariably I already know why there's a difference. It's not that they don't have the technical ability or knowledge to shoot wonderful photographs. It's ordinarily their approach, their conception of their photographs and the process to make them. Simply put, it's the difference between a snapshot and a photograph.

When I'm out touring I don't merely “point and shoot.” I look for specific composition possibilities to show off the natural beauty, the architecture, history, landmarks, the general location, the culture of the location, etc., before me.

I take time to get away from the viewfinder to see and experience where I am, rather than immediately point and shoot at each scene or landmark I see. If your trip is always revealed from the narrow viewpoint of your camera's viewfinder or monitor, you'll miss far too much of the travel experience. You'll miss the fun of travel, much of the interaction with what surrounds you, and you'll miss the best photographs too.

Smartphone Apps for Photography: PhotoCalc

PhotoCalc LogoOften, today's SLR/DSLR lenses don't have Depth of Field (DOF) markings, so you can't directly tell, in advance, what will be in and out of focus in your photograph.

When you're using manual exposure, are you experienced enough, and is your memory good enough to know what your exposure reciprocation table will tell you when you want to adjust your aperture and shutter speed to produce specific effects?

Have you been leery of using your flash in manual mode to obtain precise results because your flash exposure calculations are too difficult?

Have you had a difficult time determining sunrise and sunset information for the area in which you're traveling so you can plan those marvelous “golden hour” photos?

Focusing your DSLR even while wearing glasses

Nikon D200 with vertical gripAccording to the Vision Council of America, about 75% of US adults use some sort of vision correction. About 64% wear glasses, and about 11% wear contact lenses exclusively, or part time with glasses the remainder of the time.

It seems safe to assume that the same percentages apply to photographers in general, including travel photographers, and those on vacation.

Unfortunately, many photographers who wear glasses seem to have difficulty focusing their DSLRs and composing their images due to their inability to see the image fully in their camera's viewfinder, “edge to edge.”

Fortunately, for most photographers who wear glasses, there are both equipment solutions and techniques to help with focusing and image composition.

We need to start with the photographer's glasses. Prescription lens glasses are either single-focus or multiple-focus. Multiple-focus lenses can be bifocals, trifocals, and progressive lenses. Of these, the most difficult to use while photographing are trifocals and progressive lenses.

Smartphone Apps for Photography: Depth of Field Calculator

Depth of Field CalculatorHave you ever taken a portrait, or a close-up of a flower or insect and wished that either more of it had been in focus, or the exact reverse, that less had been in focus?

I sure have. When shooting wildlife, such as birds, I normally want the entire bird in focus, but sometimes I don't close down my aperture quite enough to ensure that that my depth of field enables me to accomplish that.

In order to know what will be in and out of focus, you'll need to know what your “depth of field” is.

It's not sharp! Are you sure it's in focus?

Morris ArboretumOne of the most asked questions I receive by email is, “My close-up photos are sharp, but the ones taken from 25 feet away or longer aren't. Do I have to have my camera focusing fixed?”

Many photographers expect that if a camera has focused properly, all their photos will look sharp.

Let me dispel that idea immediately. It's not true.
Sharpness is, to a large extent, in the “eye of the beholder.” While one person may consider a photograph sharp, another person might not. Don't ask me to define sharpness, I can't. Nikonians tried, but personally I think its definition (below) is gobbledygook.

Night Photography: Overcoming the Obstacles, Reaping the Rewards

Bruges: The Belfry and Cloth HallIn last week’s article, Night Photography: Pushing the Limits, Understanding the Obstacles, I discussed some of the difficulties encountered in Night Photography.

In this week’s article, I’ll discuss how to overcome those problems to produce wonderful night images which help tell one’s travel stories.

When it’s possible to use one, the tripod is absolutely the best tool for photographers to make great night photographs. A well-chosen tripod with a quality “head” can enable photographers to hold their cameras motionless to create high quality night photographs.

Night Photography: Pushing the Limits, Understanding the Obstacles

Las Vegas at NightPhotography at night has plenty of obstacles, but is also full of rewards for travel photographers.

Many locations have interesting sights and looks during the day, and a whole host of different sights and looks, and another atmosphere in the evening. Las Vegas many interesting photographic opportunities during the day, but it seems as though it’s at night that Las Vegas really comes alive. The night photography opportunities in Las Vegas are almost limitless.

Paris at night: view from the Eiffel TowerAnother location with great night photography opportunities is the “La Ville-Lumière” (The City of Light). While Paris, France, was originally given that nickname due to its fame as a center of education and thought during the Age of Enlightenment (eighteenth century), its early adoption of street lighting (In 1828, Paris began lighting the Champs De Elysées with gas lamps. It was the first city in Europe to do so.), and its use of electric light beginning in the 19th century for street lighting and later to illuminate monuments established the nickname forever.

Traveling with a tripod: It's love — Hate

You know, it really is a love — hate relationship between travel photographers and their tripods. Some weigh so much you get tired just looking at them in your room. When traveling with a group, you may get some “evil eyes” staring at you while you take time to set them up and take them down.
Monument Valley, Utah





 Unfortunately, without a tripod, you can’t get really good night photographs, multi-image panoramas, sharp wildlife photos at distance, or sharp macro photographs of beautiful blooms, even with lens vibration reduction or camera image stabilization.

If you don’t have a tripod, or are considering one, but haven’t yet purchased one, it’s time to look at what benefits to travel photography you can derive from taking a tripod with you.
  • Enhance sharpness — The “Photography Hand Holding” rule of thumb, for 35mm camera “equivalent” focal lengths, is the slowest hand-holdable shutter speed is 1 divided by the focal length of the lens. A 200mm lens can be hand held no lower than 1/200 sec. For print sizes of 8x10 inches and larger, even 1/200 is too slow. While some people can hand hold better than others, and lens vibration reduction / camera image stability can help, when you get to it, the rule is accurate. A sturdy, stable, properly sized tripod will get you sharper pictures every time.
  • Create photographic opportunities — There are many photographic opportunities for which a tripod is essential; night photography, time-lapse photography, macro photography, wildlife photography, timed delay exposures, panoramas, etc. You might use a tripod to be creative such as in action photography where you pan with the subject and blur the background to show movement.
  • Use lenses with longer focal lengths — The longer your lens’ focal length, the higher the magnification of your image, the more difficult hand holding the lens will be, and the more likely the image will be blurred by even a minute amount of camera shake. The longer the lens, the more the shake will be amplified. Vibration reduction and image stabilization cannot eliminate camera/lens movement as effectively as a properly sized tripod.
  • Enhance photographic image quality — When you hand hold your camera in low light conditions, you often must either use faster film, or set your sensor ISO setting higher on your digital camera, since there is a lower limit in reducing your f/setting, when you try to keep your shutter speed high enough to hand hold your camera. By placing your camera on a tripod, you can keep your film speed or ISO setting low, improving your photograph’s quality.
  • Enhance depth of field — When you hand hold in low light, you must use a low f/setting, opening up your lens’ aperture to let more light in, and/or a high film speed or ISO setting. Using a low f/setting reduces your photograph’s depth of field. Using a tripod enables you to use higher f/settings, closing the lens’ aperture to create a longer depth of field.
  • Reduce distortion — Some better tripods allow you to get close to the ground for extreme low-angle shooting. This in turn can help you better compose the photograph and minimize keystoning and other types of distortion.
  • Enhance image framing — There’s nothing better than a tripod in assisting a photographer to control the camera/lens position to permit you to perfectly compose your photo by using its panning and tilting movement.
  • Enhance videos — You’ve seen TV cameras at sporting events, news events, and other locations. Many, especially the ones far from the action, are on tripods. There is no doubt that their use for video reduces camera shake and ehances smooth panning to follow movement. With more and more digital still cameras able to take short videos, tripods for those shots are becoming more important daily.
  • Enhance flexibility — You can use a tripod like many photographers to hold more than just a camera. I’ve often used a tripod as a light stand, or to hold a reflector.
  • Enhance photographer’s discipline — In my article, “Get great photos from your camera, instead of whining about needing a new one,” I said, “All too often digital camera ‘users’ just point their camera in the direction of their subject and shoot. No thought goes into photographic composition or exposure.” It takes a bit of time to set up a tripod with a camera and lens. This is a great time to think about your image, set an appropriate exposure, and carefully compose the photograph with thought.”
The Louvre at Night, Paris








 Perhaps you think a tripod is only for expensive SLR or DSL cameras. Think again. If you have a Point and Shoot camera, look on the bottom of the camera. I’ll be you’ll find a threaded hole for attaching a tripod. Tripods work effectively for all kinds of cameras. You just need the right one.

Next week I’ll discuss choosing the right tripod.

Ten Tips to Improve your Landscapes

Sculling on the Schuykill RiverIt’s Spring. We’ve had days in the 90’s and days in the 50’s, days it’s been sunny and days its poured and poured, days it’s been calm, and days the winds have gusted over 50mph. Such is spring in the Northeast, but it’s been so great to be beyond the grip of winter.

With digital point and shoot cameras and consumer DSLRs so easy to use to make high quality photos, the number of Philadelphian’s and visitors walking on the paths beside the Schuylkill River a couple of weeks ago, to watch and take photos of the shells rowed quickly down the River, and the beautiful landscapes of Fairmount Park’s flowering trees along the River was amazing.

As I watched the scenes revealed as I walked up the River banks, I thought I might discuss some ideas I’ve learned about making landscape photographs better, here on the Blog.

  1. With film, there was a real cost per photo, so photographers gave thought to composing each one. With digital image costs at almost zero, that impetus for thoughtful image composition disappeared, and now too many travelers bring home too many poorly composed images. I see travelers so excited to arrive at their destination, that they start taking photos willy-nilly. Take a breath, take in the scene, then compose an image which shows off the scene well. That way you’ll make photographs, not take snapshots.

  2. Monument ValleyMaximize your depth of field (well most of the time anyway). Generally you want to ensure that as much of your image as possible is in focus. The easiest way to do this is to choose a small aperture setting. The smaller your aperture, the greater the depth of field in your photos. Don’t forget, a smaller aperture means you’ll need to decrease your shutter speed, or increase you sensor sensitivity (ISO setting) to get the correct exposure, or a combination of both.

  3. Sometimes to help your image have a more natural look, and focus on an object in the foreground, or the foreground itself, you might want to narrow the depth of field. This can give the image a real sense of depth, and give the viewer a way into the photograph. I often choose this, to emulate the way we actually see a large landscape, by keeping the foreground and mid-ground of the image in sharp focus, but allow the background to be somewhat fuzzy. When we look at a scene and concentrate our eyes on the foreground, the background is generally somewhat out of focus.

  4. Galapagos, Puerto Egas, Santiago IslandLandscapes need some sort of focal point to avoid ending up looking rather empty. Focal points prevent your viewer’s eye from wandering, with no guidance of where or how to look at your photograph. Focal points can take many forms in landscapes from buildings, trees, boulders, birds, ships, islands, a person, silhouette, etc.

  5. Consider using the sky to enhance your landscape. Many great landscapes will either have a dominant foreground or sky to eliminate your photo from being boring. If your sky is bland, compose your landscape to focus on its foreground by placing the horizon in the upper third of your shot (Remember my article on the Rule of Thirds.) If the sky is filled with drama, interesting cloud formations and colors, let it dominate by placing the foreground lower. You can even enhance skies via a polarizing filter or in post production.

  6. When people think landscapes, they think of passive environments, still lifes, but many of the great landscapes show motion and the movement adds drama, mood and points of interest. It could be waves on a shoreline, a waterfall, moving clouds or birds flying, for example.

  7. Scotland, Highlands, Dornoch FirthAfter you take that breath, while you’re composing your landscape image, one question to ask yourself is “How will you lead the viewer’s eye in the photograph?” We’ve already discussed some methods. Another is to provide viewers with lines that lead them into and through an image. Lines give images depth, scale, perspective and can be a point of interest, creating patterns in your image.

  8. Photograph during the “golden hours,” the hours near dawn and dusk. This is the time when the light must travel through the atmosphere the longest distance, which effects it’s “golden” color. The light being low also creates shadow, and helps define shapes better with improved contrast, interesting patterns, dimensions and textures.

  9. Think about the horizon in your landscapes. While you can fix the horizon in post processing it’s better if you get it right when you take the photo. Ask yourself if it’s straight, if it should be, and if it’s in the right place to make the best landscape possible. Think about that rule of thirds I keep mentioning. It works.

  10. Remember it’s not the camera which creates great photographs. Photographers create great photographs with their minds, hearts and senses.

It's spring! Getting those close-up shots while traveling

Spring has just come to the Northern Hemisphere. Flowers are blooming and the colors are spectacular. Each spring more and more travelers tour famous gardens to photograph and drink in their magnificent blooms.

Around Philadelphia, traffic to Winterthur and Longwood Gardens dramatically increases in the spring. In the Netherlands it’s time to visit Keukenhof Gardens, just outside of Los Angeles, the amazing Huntington Botanical Gardens, and also in Scotland, Castle Kennedy and Gardens. They are all exquisite.

Morris Arboretum - Bee In RoseThis spring, travel photographers will pull out their macro lenses to get close-ups of garden blooms. If you don't have an expensive SLR (single lens reflex), or DSLR (digital single lens reflex), with extra care, a good P&S (point and shoot) camera can grab the shots too.

In general photography, we record sharp images with ease, as most photos such as landscapes, are taken at a distance. In macro photography, we take photographs of small and sometimes tiny objects, which require the lens to be positioned close to the subject, often less than a foot away. That makes it much more difficult to record a sharp image.

Morris ArboretumIf you have a quality SLR or DSLR with a macro lens attached, you will have a great advantage over other cameras to get that sharp close-up image. If you have a tripod you'll have an even greater advantage.

That being said, here are some tips to get great close-up photographs:

  • Compose your photo carefully, as the subject’s background can make or break a close-up picture. Use the background to complement the main subject, not detract from it.

  • Consider opening up the lens’ aperture to reduce depth of field. In the photo above, on the right, taken at the Morris Arboretum, note the background is not in focus, while the plant is in sharp focus, making the plant stand out, almost in 3D. This was accomplished by opening the lens to f/5.6.

  • Garden of Eden Botanical Garden - Bee in LotusFocus your camera carefully. As in telephoto photography, focus is critical. Focus on the most important element in a scene. Shoot at a small aperture (f/11, up) for good depth of field, unless you want the area in front of and behind your subject out of focus. In the lotus flower photo to the right, I focused on the bee, and used an aperture which kept the entire lotus in focus.

  • Steady your camera. Close-up shots exaggerate camera shake. To reduce camera movement, which is most noticeable in natural light pictures, use a tripod. For the photo of the bee in the lotus, I used a tripod when I took it at the Garden of Eden Arboretum and Botanical Garden in Maui.

  • Another way to reduce or eliminate the effect of camera shake is to use your camera or lens’ image stabilization or vibration reduction ability. Please remember, however, while they can really help, they are no substitute for using a quality tripod.

  • Set your digital camera’s image quality to RAW, if your camera has it. The RAW setting gives you more exposure latitude than JPEG (JPG). In close-up photography you try to record tiny details, so save the image at the highest quality available in your camera. If you can’t save images in RAW, use the highest quality JPEG setting, such as "superfine, large."

  • Set your digital camera's ISO (sensor sensitivity) to the lowest possible setting according to conditions, to reduce noise and artifacts which are troublesome in macro photography. For film cameras, use film with a low ISO rating. An ISO of 100 is ideal.

  • Morris AboretumConsider adding light (flash), even when outside. A ring light, or a system like the Nikon R1 is a good choice. The light they produce can add contrast to a photograph, making it look sharper. The built-in flashes in DSLRs and P&S generally will not work well for macro photos, and are better turned off.

  • Look for different viewpoints. Different angles and shooting distances can greatly affect your macro shot. Sometimes moving just a faction of an inch can provide a completely different view of the same subject. Experiment with color, and black & white.

  • Many point and shoot cameras have a macro mode. Use it. Macro mode allows your camera to focus on a subject closer to your lens than normal. Most macro modes will set your camera to choose a larger aperture, so that your subject is in focus but the background is not.

I love visiting gardens myself, and taking hikes through parks and forests while taking close-ups of flowers. I hope you enjoy bringing home great plant, flower, and insect photos from your spring travels.

Photographing through glass and Plexiglas

While traveling, we often run into challenging photographic situations: a helicopter or small plane flying over the glaciers of Alaska, a glass wall protecting the Pandas at the National Zoological Park, a glass display case containing a great work of art at the Louvre, or a striped burrfish behind the glass of the National Aquarium. You might even want to snap a more mundane photograph of people at work, behind a large, plate glass window.

Great photos can be crafted in each of these situation, but you must be prepared to meet the "glass challenge;" reflection and focus.

Reflections on glass can be a photographer's bane, but sometimes a friend. One of the biggest problems with reflections is our brain works so well that sometimes we don't even notice small ones, but the camera doesn't miss a thing. As photographers, when working through glass, we must make ourselves aware of these reflections, which sometimes can even be us, or our clothing.

When shooting through glass, some cameras have trouble focusing on the subject and attempt to focus on the reflections on the glass. This must be overcome.

Tailors window in Old City Philadelphia
In the above photograph of a tailor shop in the Olde City area of Center-City Philadelphia, I wanted to capture the whimsy of the window painting of a tailor at a sewing machine. That required me to focus at the window, and use a midrange aperture (f8) to create significant depth of field to keep the shop in focus behind the window. Fortunately, when I came by the shop, the sun was behind the buildings across the street, so sun and building reflection was at a minimum, however, I had to wait for traffic to move past the shop to eliminate their reflection.
  1. If you can, don't use a flash. That will immediately eliminate its self-reflection. When you must use a flash, do not direct its light straight on or you will get a photo of the flash of light it produces. Move the flash head to an angle so the flash's reflected light bounces off the glass at an angle, not directly back into the camera's lens. If you're taking a photo through a display case, and have an "off camera" flash, try using the flash from above the case. Using a "fast lens," a lens which can open its aperture very wide, can mitigate the need for flash use.

  2. Perhaps the easiest was to eliminate reflections and focus problems is to hold the camera as close to the glass as possible to avoid glare and reflections. If you can, use a rubber lens hood, if you have a DSLR, to seal out light, or if its a point and shoot camera, use your hands at the side of the camera to do the same. This also has the benefit of eliminating problems of dirty glass as you will be focusing past the dirt on the subject behind the glass. If you need a wide view, use a wide angle prime or zoom lens. This is a great way to photograph at an aquarium.

  3. Sometimes you can't get very close to the glass, since you want a wider view of the subject behind it. If the light is from a single source, such as often found in a museum, or even multiple sources, stand to the side of the subject to minimize the reflections from the light and eliminate your reflection.

  4. You can use a circular polarizing filter almost anytime you are shooting through glass, or water for that matter. Circular polarizers are necessary with today's through the lens metering (TTL) and auto-focus cameras. Linear polarizers, though more effective, generally render TTL and auto-focus ineffective.

  5. If you're shooting through a window of a moving bus, or a helicopter there are several things to do. Use a fast shutter speed. That will help you negate the movement of the bus. Consider manually pre-focusing your lens, or if your camera has the capability, use continuous focusing. Try setting your aperture at mid-range which will lengthen the depth of field, making up for focusing inaccuracy. If your DSLR lens has vibration reduction (VR), use it, especially if it has active VR. If your point and shoot camera has image stabilization, use it. Get as close to the window as possible, without touching it, to eliminate glare and reflection from inside the bus. Try a trick suggested to me. Use the rubber end of a light weight toilet plunger. Cut a hole in it for your lens and use it to block the light from inside, with the lens close to the window.

    Some people suggest the use of a circular polarizer when shooting through the windows of a helicopter or bus. It definitely can help you lessen or eliminate the refections on the window glass, or helicopter's Plexiglas, but if you've ever worn polarized sunglasses while in these vehicles you already know that it will accentuate the stress marks in the Plexiglas or the spots in the safety glass. Personally, I wouldn't use one when photographing from a helicopter or bus.

    If you have the option, shoot through the open door of a helicopter, instead of a window. It will make it easier to get great photos. You can be buffeted badly by the turbulence with an open door, so be prepared for that.

  6. If you know you're going to be shooting through glass, especially if you're in a moving vehicle or helicopter, wear dark clothing to minimize your reflection.
Bar Window in Old City Philadelphia
When shooting with available light, as I did for the photo above, there are times when a little reflection can be a good thing. By focusing on the window itself, I was able to capture the neon signs in this bar window, plus the reflection of the sky, and the buildings across the street, to add to the shot's context and make the photo far more interesting.

Enjoy the "glass challenge."
