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?

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?

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

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

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
