'The film now is so expensive. I hate spending that much money on each shot' — photography icon Sally Mann finally switches to a digital camera after decades using film

American photographer Sally Mann at an awards event.

I'll always remember seeing Sally Mann's photographs for the first time – it was when I studying photography at college some 25 years ago. My first taste was her polarizing Immediate family series – monochrome images mostly of her children, shot using 8 x 10-inch sheet film.

There was a timeless beauty to those photos, which were painstakingly made with a large-format Deardorf 8 x 10 bellows-view camera – if you're interested, she outlines her workflow in this CBS Mornings feature.
