Why use pictures at all
Words are slippery when people talk about places. Ask residents whether they want “more character” or “a livelier street” and each person may picture something different. Showing an image can make the question concrete: here is a street with low brick buildings and trees, and here is one with a wide road and large parking lots. Which do you prefer, and what do you notice about it?
Visual methods are used to start conversations, to reach people who may not speak at formal meetings, and to turn vague preferences into things a designer can respond to. They are most helpful as one way of listening, not as a vote on what to build.
Visual preference surveys
In the classic form, participants are shown a set of images of streets, buildings or public spaces and asked to rate each one, perhaps on a scale from “dislike strongly” to “like strongly.” The images are displayed in a slideshow, on a board or online. The ratings are then tallied to see which kinds of scenes tend to be liked and which are not.
Variations include:
- Paired comparisons. Two images at a time, with the participant choosing one.
- Sorting exercises. People place cards with photos into groups, such as “belongs here,” “does not belong here.”
- Dot voting on a wall of images. Participants place stickers next to the ones they like most, which is quick and works well at events.
- Comments with ratings. Asking participants to say why they chose an image often yields more than the rating alone.
Photo methods that start with residents
A second family of methods flips the arrangement: instead of showing people pictures chosen by planners, residents take the pictures.
Photo-elicitation. Residents photograph places they like, dislike, use often or avoid, and then talk about the images in an interview or group. The photograph serves as a prompt for explanation; what matters is what the person says about it.
Photovoice-style projects. A group of participants takes photos around a theme such as “getting around,” meets to discuss them, and may present the collection to decision-makers. The approach is designed to bring in perspectives that formal surveys miss, for instance those of young people, older adults or people using mobility aids.
Mapped photos. Pictures are tagged to locations on a map so that patterns, such as a cluster of photos of broken pavement or of a favorite corner, can be seen together. Combining images with ordinary planning maps gives location to the stories.
Before-and-after photography. Photographing the same spots over time is a simple way to document change. It differs from preference methods, but the same images can help residents and staff talk about what is better or worse.
What these methods can reveal
- Features people react to. Trees, awnings, stoops, window displays, benches, signs and building height often come up. Patterns across many ratings can point to elements that matter to the community.
- Reasons behind opinions. A stated dislike of “modern buildings” might turn out to be a dislike of blank walls, which is a more specific and addressable concern.
- Everyday use that planners miss. Resident photos can show shortcuts, informal gathering places or hazards that are not on any map.
- Disagreement within a community. Different groups often respond differently to the same images, and showing that is more honest than reporting a single average.
The limits of the method
Visual surveys are popular partly because they are easy to run and easy to present. Their weaknesses are significant, and it is wise to know them.
The choice of images shapes the answers. If every “good” example is a leafy, low-rise street photographed on a sunny day and every “bad” example is a gray parking lot in the rain, the results mostly show that people like sunshine and trees. Images should be matched for weather, time of day, camera angle and quality, and the set should include fair examples of the options being discussed.
People respond to style, not substance. A rating of a photo is a reaction to appearance. It says little about whether a street is safe, affordable, quiet or functional. A building that looks pleasant may have no ground-floor activity; an unglamorous one may serve many people well.
Familiar looks get higher ratings. Participants often favor what resembles their own experience, which can discourage unfamiliar but potentially useful types of housing or mixed-use buildings. The results may reflect habit more than considered preference.
Who responds matters. An online survey may attract those with more time, internet access and interest. A tally of ratings is not representative unless the sample is. The gap in who can take part is related to wider issues such as the digital divide. Offering paper boards at libraries, events and on the street helps reach others.
Photos flatten experience. A still image cannot convey sound, smell, traffic speed, temperature or how it feels to cross at a busy intersection. For this reason, the photo should be combined with other methods, such as a walk audit.
Results can be used to justify decisions already made. A survey that confirms a preferred design can be presented as a mandate. Because the questions and images were chosen by the organizer, the findings need careful framing.
Photography raises privacy and consent questions. Photos that include identifiable people or private property should be handled thoughtfully. Participants should know how the photos will be used and have a way to withdraw them, and organizers should follow any local rules on image use.
Designing a fairer visual survey
- State the question clearly, such as “Which of these streets would you like to walk along?” rather than “Which is best?”
- Select images systematically, with several examples of each type and consistent conditions, and show some that challenge the organizers’ own preferences.
- Randomize the order so that early images do not set expectations.
- Pair ratings with open comments to learn why.
- Record who responded, including broad age groups and neighborhood, and say who is missing.
- Pretest with a few people to catch confusing or biased images.
- Report disagreement, not only averages, and state the limits openly.
- Treat results as input. They inform design discussion, but should be combined with data on safety, cost and use, and with dialogue in forums such as community engagement events.
Where this fits
Visual and photo methods are inexpensive ways to hear from residents about how places look and feel. They work best when residents help choose or create the images, when the limits are acknowledged, and when the findings are weighed alongside other evidence. A bright set of ratings can start a useful conversation; it should not end one.
