6 Winning Ways to Work Wide

Bridgetown Night Panoramic by Jaryd Niles-Morris 2008

One of the first lens purchases aspiring landscape photographers typically made is a wide or super-wide lens, anything (in full-frame 35mm terms) from 24mm on down, and with good reason, wides offer photographers the ability to capture the sweeping vistas of the natural landscape. But they can also be a challenge to use effectively, it's all to easy to end up with a wide-angle shot that lacks the power and grandeur we felt when we were shooting. In this article, I'll explain why that's so often the case, and provide a few tips for working around those challenges, showing you how to use wide-angle lenses to create dramatic, effective images.

1. Get Close!

Because wide-angle lenses take in a bigger angle-of-view than other lenses, using a wide-angle lens at the same distance from your subject will render that subject smaller than it would otherwise. To compensate for this, you'll have to move closer to your subject. Don't be bashful about getting close, particularly with super-wides&mash;it's almost impossible to get "too close" to your subject with a 14mm lens. This emphasis in size that wide-angle lenses give nearby objects means that ...

2. It's All about the Foreground

Contrary to what you might expect, this means that the most important element of your wide-angle landscapes is the foreground. While wide-angle lenses do capture the wider landscape, they also (almost inevitably, because of their wide field-of-view) capture quite a bit of foreground as well, and this foreground is emphasized by the wide-angle perspective. As a result, if your foreground isn't interesting, your photograph won't be interesting. This leads us naturally to the Josef Muench idea of the near-far composition, an image which uses a wide-angle lens to not only show a broad vista, but also to show one detail of that landscape in an up-close, intimate way. When you're photographing wide, be sure to spend some time looking for the most interesting foreground available to combine with your grand vista. (If there isn't an interesting foreground, you might want to consider using a longer lens to leave out that less interesting foreground.)

3. Watch those Verticals!

Wide-angle lenses tend to bend and distort verticals, as you can see in the tree trunks near the top of Fallen Redwoods. Now, you might decide you like that effect, or that you hate it, but it's important to be aware of it and to make a conscious decision about it. For some images it's fun to embrace, but more often I find myself having to work to avoid it or correct it later. Avoiding it can be as simple a matter as composing so that there's only a single obvious vertical (and that that's vertical), alternatively, using shift movements with a tilt-shift lens can correct some of this distortion in-camera. Post-exposure, Photoshop's "Lens Distort" filter can also save the day. 4. Leading Lines

Compositionally, lines (such as streams or railway tracks) leading from the bottom corners of an image towards the center often have a particular magic for guiding the viewers eye through the picture, making for strong images, and this is particularly the case for wide-angle images. Hot Stream is a great example of this, the viewers eye tends to wander from the corner back through the image along the stream. As the stream moves back into the image, the stream gets smaller (in terms of inches on the printed page) quickly due the wide perspective. This quick fade (in width) into the distance creates a real sense of depth in the image.

5. Filter Woes

Shooting wide creates two problems for those of us who use filters. Polarizers are a specific problem, the effect of a polarizer on a blue sky varies across the sky so greatly that wide-angle images including the sky are left horribly unnatural, so leave off the polarizer unless you know there's no blue sky in your scene. Screw-in filters are a separate problem, it's all too easy for the filter edges, particularly if you're stacking more than one filter on the same lens. Filter systems, such Cokin's P-series filters (with the wide-angle filter holder), can help you avoid these problems if you must use filters.

6. Focusing

One of the things I enjoy most about working with wide-angle lenses is the ease of focusing them. As you move to wider and wider focal lengths, the depth-of-field at a particular aperture gets deeper and deeper. This allows you to make great use of the concept of hyperfocal distance, that is, the nearest distance you can focus a particular lens at a particular aperture and get "good focus". At 24mm, by focusing about six feet out from the camera you'll capture everything from about three feet to infinity in focus--even at f/11. At 17mm, focusing at the right point at f/11 will get you everything from infinity down to 17 inches away. Find (using a web site like this or any of a number of other sites, software tools or printed tables) and write down the hyperfocal distance for a couple of your widest lenses at a couple of your favorite apertures, and you'll have an easy way of bringing the entire scene of near-far compositions into critical focus.

Using wide-angle lenses can certainly be tricky, but I love them all the same. Used well they can allow the photographer to create images that immerse us in a world with both small, intimate details and bold, dramatic vistas.

Shooting Tack-Sharp Images

Novices to experienced photographers may be surprised to know that there are many different factors that influence your overall image sharpness. Here is a brief summary of each area that can potentially affect your image clarity.

I. Shutter speed - Shutter speed is probably the first thing most of us think about when shooting tack-sharp images. Our first lessons in SLR photography are how camera shake and movement can ruin a picture if your shutter speed is too low. For more information on shutter speed and what your minimum shutter speed should be, check out our article Shutter Speed Guideline – The Reciprocal Rule.

II. ISO - The second thing that may come to your mind is your ISO setting. While ISO speeds up the process in which your film/sensor absorbs light, it also adds grain to your image. This grain destroys detail/sharpness in the image. The higher your ISO setting, the more detail is destroyed. New professional DSLR cameras such as the Nikon D700 and the Canon 5d Mark II (and higher models) can shoot at much higher ISO settings while retaining much of the image detail. However, with the proper lighting, it is usually best practice to shoot at the lowest ISO setting possible.

III. Lens quality - The quality of the "glass" (lens) contributes to image sharpness, contrast and saturation. For the most part, professional series Nikon and Canon lenses produce sharper images than cheaper lens models or third party lens manufacturers. However, this generalization does not apply to all lenses, and some tests for select lenses have claimed better overall sharpness from third party manufacturers than their Nikon or Canon counterparts. Does this mean you should buy third party glass? Usage and budget are important factors; but keep in mind that cheap glass, in general, will already put you at a disadvantage when trying to create tack-sharp images.

IV. Image area - In composing your shots, keep in mind that different areas of the image will be softer (less sharp) than others. The center of your frame will always be your sharpest point, while the image will only get softer as you continue to the edge of the frame. While shooting your subject off-center for composition purposes is often necessary, it isn't in your best interest to compose shots carelessly because you are relying on cropping the image down in post production. In general, areas away from the center will be less sharp relative to the center at wider apertures (F1.4, F2.8, etc), while areas away from the center will have similar sharpness as the center at smaller apertures (F8, F11, etc).

V. Aperture setting - Aperture is probably the last thing you would think of when it comes to obtaining tack-sharp images. However, it is one of the largest determining factors of shooting tack-sharp images. We all know that aperture controls your depth of field. However, did you know that shooting the exact same shot with the exact same focal point will yield different levels of sharpness on your focal point at different apertures? For example, if I focus on the nose of a face at F1.4 and with the exact same exposure value and composition, shoot the same face at F4.0, the nose will actually be sharper in the image shot at F4.0. This is simply because each lens has a "sweet spot."

Shooting at your lenses sweet spot will improve sharpness, contrast and saturation. Now you may be thinking, "well how do I find the sweet spot on my lens?" There are several rules of thumb, but the most prevalent is that your sweet spot is around 2 full stops above your lens' minimum (widest) aperture. Depending on the lens, this will be in the range of F4-F11 or so. Keep in mind though, raising your aperture too high (small) will result in aperture diffraction, another phenomenon that will reduce overall clarity. For more information on diffraction, read our article Avoiding Aperture Diffraction.

One last thing, before you go shooting all of your images at your "optimal aperture" setting. Keep in mind that composition always rules! If blurring the background to make the subject "pop" is part of your look and composition, then shoot the lowest aperture possible! A well exposed composition shot at F1.4 will still be plenty sharp for any purpose, it just may not be considered "perfectly tack-sharp." However, we should always think of composition first, and when appropriate keep your aperture within its sweet spot.

Last but not least, Digital Photography Review has an amazing widget that allows you to check out the sweet spot on pretty much any lens.
