Visual Elicitation Case Study
Also known as: photo elicitation case study, image-based case study, visual methods case study, elicitation-based case study
Visual elicitation case study is a qualitative design that embeds photo or image elicitation within a case study framework. Participants respond to photographs, drawings, or other visual materials during in-depth interviews, generating richer and often unexpected data than verbal questioning alone. The case study structure then situates these image-prompted accounts within a bounded real-world context — an individual, organization, community, or event — enabling a holistic, detailed understanding of the case.

When to use it
Use visual elicitation case study when your research question centres on how participants perceive, experience, or make meaning of a specific bounded context — particularly when verbal questioning alone is unlikely to surface tacit, embodied, or emotionally laden knowledge. It is especially powerful with populations who find verbal articulation difficult (children, trauma survivors, or speakers of a non-dominant language) and in settings where visual culture, built environment, or material artefacts are central to the phenomenon. Avoid this design when participants cannot meaningfully engage with visual materials, when the research requires statistical generalizability, or when the phenomena of interest are purely abstract and not amenable to visual representation.
Strengths & limitations
- Images lower cognitive and emotional barriers, eliciting richer, more candid accounts than verbal questioning alone.
- Combines the depth of elicitation interviewing with the contextual rigor of case study triangulation.
- Well-suited to capturing tacit, embodied, or place-based knowledge that resists direct verbalization.
- Participant-generated photography (photo voice) shifts interpretive power toward participants, supporting reflexive and participatory approaches.
- Visual materials provide a stable, shareable record that can be independently interpreted and compared across researchers.
- Collecting, organizing, and analyzing both visual and verbal data is time-intensive and requires training in both image analysis and case study methods.
- Ethical complexity is heightened when photographs include identifiable people or sensitive locations; IRB protocols must address image consent and storage.
- Findings are context-specific and bounded by the case; statistical generalization is neither possible nor the goal.
- Participants may interpret images idiosyncratically, making cross-participant comparison challenging if image sets are not standardized.
Frequently asked
Who produces the photographs — the researcher or the participants?
Both approaches are used and can be combined. Researcher-produced images offer consistency and can target specific aspects of the case, but risk embedding the researcher's perspective. Participant-produced images (photo voice or photo diary) give participants greater interpretive agency and often surface unanticipated dimensions of experience. The choice should be driven by the research question and the degree of participant involvement desired.
How many cases and participants do I need?
A single revelatory or intrinsic case can stand alone if it is sufficiently rich and the research question is case-specific. Multiple cases (typically two to five) are used when cross-case comparison is theoretically motivated. Within each case, interview participants are selected purposively; the number depends on data saturation rather than statistical power, with five to fifteen participants per case being common.
How do I analyze the visual materials themselves, not just the verbal responses they prompt?
Visual content analysis or compositional analysis can be applied to the images in parallel with thematic coding of transcripts. The researcher attends to what is depicted, how elements are framed, what is absent, and how the image relates to the verbal account it generated. Software such as NVivo allows images and transcript excerpts to be coded side by side, supporting integrated analysis.
Is this the same as photo voice?
No, though both use participant-produced photographs. Photo voice is a participatory action research method developed by Caroline Wang and colleagues, oriented toward community empowerment and policy advocacy. Visual elicitation case study is primarily an analytic design aimed at understanding a bounded case in depth; it does not require an advocacy outcome and can use researcher-produced, archival, or participant-produced images.
What are the main ethical issues?
Key issues include informed consent for photographing people and places, participant confidentiality when images are used in publications, secure storage of image files, and the right to withdraw images after the interview. When participants photograph their own environments, additional consent from third parties appearing in images may be required. Ethics approval should specifically address the visual component of the study.
