Photography can be truth, and then it can not. It can honestly tell the emotions of the people in the pictures, or it can be staged to make the people look like things they're not. If a photograph is a candid or unedited, I think it is more truthful then one that is not because it shows raw emotions expressed by people when the photo was taken.

The men both shoot great pictures that have some similarities and differences. The first link bring you to pictures of a bunch of different things. There doesn't seem to be a common theme there like the second link's pictures have. The second link has a theme of black and white and things related to boxing while the first is a mix of color and black and white and there's not one main focus.
