im pretty sure that it will be used 50yrs from now, just who knows what for i doubt it will ever be extinct... everything is changing but some people really like how that black & white stands out from color,......... but you never know
Black and white has been obsolete for about fifty years.
The reason it's still alive is
1- It's "arty"
3- It's seen as somehow "true". Think about all the charity adverts that use black and white photos of suffering; they use it for a reason.
