I brought the case to a public discussion: Commons: Village pump #File:Logging oregon.jpg: an expert on ancient photography needed. Incnis Mrsi (talk) 20:36, 26 July 2013 (UTC)
The lighting in the photo appears unusual (for a forest) because of second light source (probably a w:flash-lamp). It is sad that you didn’t consider my arguments thoroughly. Thank the discussion at File talk: Logging oregon.jpg #Discussion that upheld authenticity of the photo. Incnis Mrsi (talk) 03:32, 28 July 2013 (UTC)
