The following link contains about a hundred high-quality photographs of members of various tribes that still exist. Of interest is that some white/Caucasian people in outdated but almost-modern clothing are featured. I believe one I saw in the gallery is a group of Russian Christians who live in Siberia and were out of contact with *anyone* for centuries.
The gallery is sadly weakened by a lack of descriptive captions, but still worth looking at:

While viewing, consider that some of the photos may be more like museum exhibits than actual snapshots of the lives of people around today.
