While working in Kabul, Afghanistan in 2007, I developed a slide presentation for staff on taking photos in the field. I relied heavily on all staff, particular Afghan staff, no matter what their job titles, to take photos whenever possible at events and workshops and during project site visits. This is because many international staff are prohibited from traveling to certain parts of Afghanistan; international staff are sometimes prohibited from leaving Kabul altogether. This presentation/training touches on both the kinds of photos needed and how to take photos in a culturally-sensitive manner. This presentation is focused on a specific program and a specific country (Afghanistan), but maybe by changing the photos and a bit of text, it could work for you?
