Hallo Sayyid, welcome to ThePhotoForum.
I don't quite understand who it is that took these photos?
You sign by "Yamandú Roos and Yours Truly".
Do you mean to say that ONE of these photos was taken by someone else and only one was taken by you?
Or do you mean to say that you are Yamandú Roos? This_Yamandú_Roos ? I'm a bit confused...
