Technique for the street

Candid photography leaves no time for fiddling with settings. When a gesture or alignment appears, the photographer has a fraction of a second to react, and a camera that is set up correctly, with focus and exposure prepared, makes the difference between a photograph and a missed moment. Street and documentary photographers therefore favour simple, reliable equipment and techniques that let them work instinctively. This lesson covers choosing cameras and lenses for the street, focal length and working distance, zone focusing and hyperfocal technique, autofocus strategies, shutter speed and motion, exposure strategies including auto ISO and exposure lock, flash on the street, working at night, smartphones, carrying and protecting gear, and personal safety.

Cameras for the street

Almost any camera can make street photographs, but some characteristics help. Small, quiet cameras attract less attention and are easier to carry all day: rangefinders, compact cameras with large sensors such as the Ricoh GR and Fujifilm X100 series, small mirrorless bodies and phones are popular. Silent electronic shutters remove the click that makes people turn (PHOT-201), though they can distort fast motion. Tilting screens allow shooting from waist level, which is less confrontational than raising a camera to the eye and gives a different perspective, much as Vivian Maier's twin-lens reflex did. Weather sealing helps in rain and snow. Physical dials for shutter speed, aperture and exposure compensation allow changes without looking at menus. Whatever camera you choose, learn it so thoroughly that you can change settings by feel.

Lenses and working distance

Focal length shapes both the look of a street photograph and the photographer's relationship with the subject. Wide and moderately wide lenses, around 28 mm and 35 mm full-frame equivalent, are the most popular for street photography: they include context, keep a lot in focus and require the photographer to be close, often within two or three metres, which creates immersive, engaged images. 50 mm lenses give a more neutral perspective from slightly farther away, the classic Cartier-Bresson approach. 21 mm and 24 mm lenses produce dramatic, enveloping images but require very close working distances and can distort people at the edges. Telephoto lenses allow photographing from a distance, which can capture unguarded moments, but they flatten perspective, isolate subjects from context and can feel voyeuristic; many street photographers avoid them for ethical as well as aesthetic reasons. Prime lenses are favoured for their small size and because a fixed focal length trains the eye to see in a consistent frame.

Zone focusing

Autofocus can hesitate or choose the wrong subject in busy scenes. Zone focusing avoids the problem: the photographer sets the lens to a fixed distance and an aperture that keeps a range of distances acceptably sharp, then photographs anything within that zone without focusing. With a 28 mm lens at f/8, focused at 2.5 m, everything from about 1.4 m to about 10 m is acceptably sharp on a full-frame camera, so the photographer only needs to judge distance roughly. Many lenses have depth-of-field scales on the barrel; for lenses without them, apps or the formulas below give the zone. Zone focusing works best with wide lenses, small apertures and bright light, and it lets photographers shoot quickly, from the hip, or without raising the camera.

The near and far limits of acceptable sharpness around a focus distance \(s\) can be estimated using the hyperfocal distance \(H\):

Here \(f\) is the focal length, \(N\) the f-number and \(c\) the circle of confusion, about 0.03 mm for full frame. If \(s\) is equal to or greater than \(H\), the far limit extends to infinity.

Autofocus strategies

Modern autofocus with subject and eye detection (PHOT-201) has made autofocus far more useful on the street than it once was. Useful strategies include using continuous autofocus with wide-area tracking and face detection for moving subjects; using a single small point placed where you expect the subject, combined with back-button focus, to lock focus on a pre-composed spot; and switching to manual or zone focus in crowds, reflections, low light or when shooting through glass, where autofocus may choose the wrong target. Test how your camera behaves in busy scenes, and know how to switch quickly between modes.

Shutter speed and motion

Shutter speed determines whether movement is frozen or blurred. To freeze people walking, 1/250 s is a common minimum; for running, cycling or fast gestures, 1/500 s to 1/1000 s. Deliberate blur can convey energy: a slow shutter speed of 1/15 s to 1/2 s with a stationary camera turns crowds into flowing streaks while static elements stay sharp, and panning with a moving subject at around 1/30 s keeps the subject relatively sharp against a streaked background. Blur from camera shake, by contrast, rarely helps; keep the shutter speed high enough for the focal length, or use stabilization.

Exposure strategies

Light in streets changes constantly as photographers move between sun and shade, so exposure must be quick and robust. Common strategies include:

• Manual exposure set for the main light, such as the sunlit side of the street, adjusted only when moving into different light. This keeps exposure consistent and avoids the camera being fooled by dark or bright backgrounds.
• Aperture priority with auto ISO and a minimum shutter speed, such as f/8 and 1/250 s, letting ISO vary with light, combined with exposure compensation (PHOT-201).
• Manual mode with auto ISO: fixed aperture and shutter speed with ISO floating, increasingly popular because modern sensors handle high ISO well.
• Exposing for highlights in high-contrast light, letting shadows go dark to simplify backgrounds and create drama.

The "sunny 16" rule, that in bright sun the correct exposure is about f/16 at a shutter speed of 1/ISO, gives a quick reference: at ISO 400, f/16 at 1/400 s, or f/8 at 1/1600 s. Shooting raw protects against exposure errors, but consistent exposure saves editing time.

Flash on the street

Flash in street photography produces a distinctive look: bright, frozen subjects against darker or blurred backgrounds, with saturated colour and hard shadows. Photographers such as Weegee, Bruce Gilden and Martin Parr used flash in very different ways, from news to satire. Fill flash in daylight can open shadows on faces in backlight. Flash is, however, highly intrusive: it surprises and can startle or upset people, and it is unsuitable in many situations, such as near drivers, at ceremonies or with vulnerable people. Many photographers reserve it for events, nightlife and situations where people are expecting photographers, or use it with consent.

Working at night

Night streets offer pools of light, neon, illuminated windows and reflections on wet pavement. Modern cameras and phones make night street photography far easier than it once was: fast lenses at f/1.4 to f/2, high ISO settings of 3200 to 12,800, stabilization and AI noise reduction (PHOT-202) allow handheld images at reasonable shutter speeds. Expose for the lit areas and let the dark areas stay dark, rather than brightening the whole scene. Find places where light falls on people, such as shop fronts, street lamps and transit stations, and wait. Zone focusing is useful in low light where autofocus struggles.

Smartphones on the street

Phones are discreet, always available and less intimidating to subjects than cameras, which makes them excellent street cameras. Their wide main lenses suit the genre, their deep depth of field makes focus easy, and computational processing handles difficult light (CRE-130). Limitations include shutter lag in some apps, limited control over shutter speed, processing that can produce an overly smooth or HDR look, and the temptation to photograph without thought. Using a camera app with manual control, locking focus and exposure, and shooting raw where possible gives more control. Many respected street photographers now work wholly or partly with phones.

Carrying, protecting and safety

Street photographers spend hours walking, so light equipment, a comfortable strap, a small bag and spare batteries and cards matter. A wrist strap gives quick access and security. Protect gear from rain with a simple cover or by sheltering in doorways. Personal safety comes first: be aware of your surroundings, avoid walking backward into traffic while composing, respect people who object to being photographed, avoid confrontations, and know when to put the camera away. In unfamiliar places, learn about local customs and risks, keep valuables discreet, and consider working with a companion. Lesson 6 discusses dealing with people who object.

Film on the street

Many street and documentary photographers continue to work with film, valuing its tonal qualities, the discipline of limited frames, the delayed result that encourages reflection, and the archival permanence of negatives. Black-and-white films such as ISO 400 stock, pushed to higher ratings in low light, have long been standard for street work, and compact rangefinders and point-and-shoot film cameras remain popular. Film requires planning for processing, scanning and storage (PHOT-240), and its costs per frame encourage selective shooting. The techniques of zone focusing, sunny 16 and pre-composing were developed in the film era and remain as useful with digital cameras.

Settings checklist for a street walk

Before setting out, many photographers prepare their camera so that it is ready the moment a photograph appears. A typical checklist: battery charged and a spare in a pocket; card formatted with plenty of space; raw or raw plus JPEG; exposure mode chosen, for example manual with auto ISO at f/8 and 1/500 s, with a maximum ISO set; focus mode chosen, either zone focus at a set distance or autofocus with a defined area; silent shutter on or off depending on subject motion; image review turned off or brief, so that the screen does not distract; and the strap wrapped around the wrist. Spending two minutes on these settings at the start of a walk avoids missing moments while adjusting menus.

Lens and sensor equivalence

Focal lengths in this lesson are given as full-frame equivalents. On cameras with smaller sensors, multiply the actual focal length by the crop factor to find the equivalent field of view: a 23 mm lens on an APS-C camera with a crop factor of 1.5 behaves like about 35 mm, and a 17 mm lens on Micro Four Thirds (crop factor 2) like 34 mm. Smaller sensors also give greater depth of field at the same f-number and framing, which helps zone focusing: f/5.6 on APS-C gives roughly the same depth of field as f/8 on full frame. PHOT-201 explains equivalence in detail.
