If you bring your camera with you in your travels - whether it’s an overseas vacation or a day trip to a local park - it’s likely that you’ll be without your tripod for at least some of the time. Sometimes it’s not feasible to carry a tripod, especially in a place where it’s simply not permitted to do so (museums, churches, etc.). Or maybe you’ll opt to leave the tripod at home and lighten your load. Street photographers work almost exclusively without tripods, as do many photojournalists and some portrait photographers. Even if you’re a landscape photographer with unshakeable allegiance to the three-legged stabilizer, hand-held shooting is an important skill to learn for those unplanned moments when a tripod isn’t set up or available.
FORM
The two most important technical considerations in hand-held photography are form and camera settings. In general, you’ll want to hold the camera with two hands and keep your elbows tucked in. The idea is to keep the camera stabilized with your body, effectively weighing it down. You’ve probably seen photographers hold the camera in one extended hand, using the display screen to focus, as they rattle off a bunch of shots. This is about looking cool while taking pictures but does nothing to improve the photo, and for most people will lead to poor results. If you are a portrait photographer using flash and fast shutter speed you could use this technique to look slick, and possibly to put your subjects at ease with a more easy-going posture, but for environmental shots using natural light I’d recommend going old-school: use two hands, look through the view finder, and hold a tight (but relaxed), stable stance. You won’t look as cool taking the photo, but you’ll get the better shot.
HAND-HELD RULE
You might know the rule of thumb to use a minimum shutter speed of 1 over the focal length. For example, if you’re shooting with a 50mm lens (on a full frame camera such as a Canon 5DSR), a shutter speed of 1/50 is the slowest recommended speed for a reasonably sharp photograph. (If you’re using a crop frame camera you need to first factor in how the crop factor affects focal length. For example a Canon 7D Mark II or a Canon Rebel T7i both have a crop factor of 1.6 which effectively magnifies the image by that amount. So a 50mm lens becomes 80mm - i.e. 50 x 1.6 = 80. In this case the minimum shutter speed is 1/80. Ok, no more math, I promise!) Let’s look at an example and see how this works in practice. We’ll assume that we do not want any creative blur and would like the photo sharp throughout.
Our location is the former mining town of Shifen, Taiwan. A slow moving train passes right through the center of the village, as it has for nearly 100 years, but these days it is carrying tourists, not coal. We’re using a Canon EF 24-70mm lens, which is my primary workhorse lens for travel photography. We’ll use a focal length of 70mm for an image of the train passing through the colorful main street - it’s safest to keep some distance from the tracks and zoom in. Notably, this lens does not have built-in image stabilization, so it’s a good test of the hand-held rule. Based on the focal length of 70mm, our shutter speed is 1/80 (the nearest increment to 1/70), and it produces a decent image. If we zoom in however, many parts of the image are soft, and the moving train is outright blurry. No amount of post-process sharpening will make this image usable in any reasonably large size. The best we can do is process this image for low resolution use, such as Instagram (or a photography blog!)
Our first attempt might be Insta-ready but it won’t cut it for a larger size image. The train simply is not sharp (our desired look), nor does it have much motion blur (an alternative look). It's neither here nor there. (Aperture: f/8.0, Shutter: 1/80, ISO: 320)
Luckily, we’re going to get another crack at it, because the train that just passed through town is going back in the opposite direction shortly. This time we are going to increase the shutter speed to 1/320. The shorter exposure requires us to let in more light, but we don’t want to widen the aperture because this will create too shallow a depth of field. Instead, we’ll meter the scene and take a few test shots with a higher ISO while waiting for the train to return. And here’s what’s key: 1) if you have time, take a few test shots to get the exposure right before the scene unfolds. 2) Don’t force a low ISO shot at the expense of sharpness. It’s true that higher ISO introduces more noise, but today’s cameras produce clean images at higher ISO and there’s always the possibility to reduce noise in post-processing. In this instance a low ISO 100 shot requires either too slow a shutter speed or too wide an aperture for this scene… so we’ll go with ISO 1000, f/8 and shutter 1/320.
PHOTOGRAPHY IN THE RAIN
We’ve got some other challenges too. It is raining and we need to keep our lens dry. You should always keep a UV filter on to protect the lens when shooting hand-held except in very specific situations. A lens hood is very effective in all but the heaviest rain. If you’ve got a weather sealed camera and lens, light rain or snow won’t be a problem, but it’s still a good idea to keep your gear dry. Buy a lens coat and if you don’t have one, improvise: a plastic bag will help in a pinch.
Now let’s look at the result. Much sharper! You can easily read the numbers on the train.
This is a crop of the train magnified to 200%. (Aperture: f/8.0, Shutter: 1/320, ISO: 1000) Minor noise-reduction was applied using Topaz DeNoise.
It turns out the hand-held rule is a guideline, not a prescription. There are many factors which would require you to keep a faster shutter speed than 1 over the focal length. Let’s review some of them:
Camera Shake Part I: Note whether your lens includes image stabilization. If it does not, increase your minimum shutter speed.
Camera Shake Part II: Consider your technical ability. Are you experienced shooting hand-held and have you practiced the skill recently? Bump up your shutter speed if you’re rusty, and feel no shame about it.
Situational Awareness: Evaluate the shooting situation. Are you calmly waiting for a moment, or did you just run to catch an unfolding scene, and your heart is pounding from the exercise and adrenaline? Can you pull off a stable hand-held shot? In high energy situations, crowded places, or bad weather this is unlikely, and you should raise your minimum shutter speed to compensate.
Moving Subjects: Visualize the scene. Are you freezing moving subjects, or capturing a still life scene? Even slow moving subjects require a shutter speed greater than the hand-held minimum. Faster subjects need even faster shutter speeds. And remember that stationary subjects are not always still (i.e. trees on a windy day.)
An example of a blown shot. I hand-held a Canon 1DX Mark II with a 600mm lens for this shot (mistake number one - hand-held shots with very long lenses are very difficult to pull off), and thought if I used a shutter speed of 1/1600 that should be plenty fast since the hand-held rule would call for only 1/600 right? Not even close. The eagle’s eyes are not sharp - which makes this shot unusable, except to demonstrate an unusable shot 😀 To get this right, the ideal shutter speed would have been 1/3200. On a tripod and gimbal, with image stabilization, steady hands, and good panning technique, 1/2500 might work. Maybe.
I have missed plenty of opportunities to capture portfolio shots because I underestimated the shutter speed needed for a sharp image. Like any photographic skill, hand-held photography takes practice and is a combination of art and science. Most importantly, go out there and have fun while you learn.
