I compare photography with horseriding. Once everybody used horses to get from A to B. Then came the automobile and horses disappeared from streets and roads. Once everybody used film to shoot family, events and tourism. Then came digimaging and film disappeared from family, tourist etc life.
But there are stiil - and will always be - those who want to ride a horse, and the same is - and will always be - true for silver-based film and paper.
Maybe the choice of products will shrink but as with horses, the lower quality items will go leaving the better (and pricier) articles available.
No reason to panic, folks!
