Here's one, maybe not the best example, except for the 100% crop that follows it. There was another that was called "agreeing terms" that is really amazing. A young political officer standing alone in front of a crowd of maybe 40-odd fully armed tribesmen, ready to accept a gift of a couple of goats! BTW I'm not absolutely certain of the copyright status of these, but given they were taken in 1919 I think it's probably OK. If someone has a rightful claim to R B Holmes copyright and objects, I'll take them down.
These were taken handheld with a 12 mp Fuji X20, no special lighting. It would be easy to do quite a bit better, and a copy stand would make it very much easier. BTW my maternal grandfather may well have been in that camp; Holmes was documenting the campaign he was fighting in, and the pics came from his album, which also includes much more amateurish shots, many in very poor condition.
