Why Are We Here?

Field studies can involve multiple team members generating thousands of digital images. How do you move from photo data sitting unused and unloved on multiple hard-disks to being a valued, relevant resource?

This workshop will cover how to: Collect, manage and stay in control collections of thousands of photos Maintain data integrity Consider moral & legal requirements Ensure that relevant data is easy to retrieve and use

All within real-world constraints (i.e. running a field project, lack of sleep, intermittent power, crashing hard disks, buggy software, sullen subcontractors, etc.)

Additional Topics to Cover

How to store data? How to share? Within groups? Structure way of re-visiting data? How to notate photos? Process for taking photos… pros and cons of different types of

camera… User identity, degrees of anonymisation Quality: resolution, composition What makes a good ethnographic image? How to select what images to use for reporting? When to delete? What to delete? Backup strategies? Photos in storytelling?

NOKIA

Software

PC Irfanview (shareware) good for keyboard shortcuts, rapid image editing, and batch

changes Adobe Elements (buggy, slow on laptop, good for setting up subcontractors to work in a

hurry) Picasa (freeware) Qualitative data analysis

ATLAS.ti (able to annotate selected parts of images) Nvivo 7

Mac iPhoto Image Capture Photoshop

Online Flickr (good for key word tagging) Shutterfly

The Challenge

right data

right format

right person

right time

How does this affect how we collect and manage the data?

NOKIA

Sample Field Study

10 days in one location 6 team members

Varying graphics skills Range of equipment – pc, macs, camera

brands Internal, external subcontractors Everyone has their preferred ways of doing

things

20+ study participants Participant diaries

Variety of data collection methods – shadowing, in-depth interviews, diaries, observations, wallet mapping, disposable camera studies, online blogs, Flickr photo diaries >> differing privacy requirements

Institutional Review Board (IRB)

IRBs are also known as Committees for the Protection of Human Subjects

Formal vs informal Age

Different levels of vulnerability seen for minors, with more protections needed

An element of rear covering! But actually a degree of flexibility when engaged – an educational process

for IRB members and applicant alike

NOKIA

The Process

Before We Get Started

Camera setup Time & date Nikon world time Sequential vs. restart File naming Folders Image resolution >> sufficient but not more Adding contact information inside memory

Storage setup Folder naming Memory cards: process me >> empties

Data manager >> someone to take overall responsibility for photo processing

NOKIA

Camera Equipment

Good for ethnographic–style work: Good quality display for showing participant’s photos Small enough to carry anywhere Steady shot Good zoom Video good enough for presentations Responsive refresh times more time taking photos than waiting for camera to

charge up Rapid on Rotating head supports more subtle photography Disable flash Night vision (Sony F717 pretty good, Sony F828

Using SLR’s, compacts, minis, camera phones, disposable, Polaroid

Consent

Data Consent USA Example UK Example India Example

Photo ownership, rights separate from Data Consent Different rights according to how the photo is used What does it mean to ‘sell’ an photo?

Sold to magazine Appears on a web site that accepts adverts? On a web site? Used in a paid-for workshop at a conference?

Model consent Consent to use photos featuring people

Keeping Participants in Control

Sufficiently aware of data collection process Asking permission prior to starting data collection Asking permission again in new privacy-breaching situations De-mystify equipment Allow participants to frame photos Rewards before data consent is signed Encouraged to delete any or all digital data Send participants a copy of the data post-study

Print or digital
