Not sure whether this counts as 'street photography', or more documentary-style 'street portraits' - captured on location, with local people, but certainly not completely spontaneous or with unaware subjects. I had anywhere from one to three off-camera strobes, mounted on boom poles carried by assistants and with light modifiers attached.
Anyway, these were taken on a recent trip to Ethiopia's Omo Valley, among the Suri people near Kibish. The tribes in this area are some of the last in Africa to live a largely traditional lifestyle in tribal groups.
All shots with Sony A1 and 70-200mm f/2.8 GM II lens with circular polariser and off-camera flash.
