Oops, I think someone missed the context of the post I was replying to.
As Salgado says in 'From My Land to the Planet", he changed because of airport x-ray machines. There may be other reasons, but that's the only one he's saying. Kodak apparently (unsuccessfully) tried to convince him that x-ray machines weren't damaging his Tri-X
He (more his lab/studio) still wet print from digital.
As far as I'm aware, Salgao hasn't shot any digital films. You're probably thinking of 'Salt of the Earth' which was shot by Wim Wenders
Re making money from selling prints - I never qualified it by saying it's enough to buy a house

. Nice Strawman.
People charge more money on a per print basis for darkroom prints vs other prints. Some photographers, especially those in the fine art world, use that as an additional revenue stream.[/QUOTe
In Salt of the Earth you can see Salgado shooting digital...and, apparently, video with his DSLR.
Nice hedge about "making money." Thousands do it with modern cameras every day. I'd guess hundreds do it weekly with film.
