I have contacted Tomas Wüthrich, a photographer who was with the penan in 2019, if I could use some of his pictures for my project. I have added the teachers to BCC. I will update the post in case of an awnser.
Pictures in question:
Tomas Wüthrich
UPDATE
I have recived an anwser from Tomas Wüthrich, I am allowed to use his pictures!
Tomas asked me, if he could have the artivle aswell, so I sent it to him aswell.
