Much of the value of Steve McCurry to us and the rest of the World is through his exposure in National Geographic. McCurry is one significant step in a process that includes logistics, editing, printing, distribution, and much more. If moving to digital enhances this complex process, then the move is good. Of course there are cameras and media that produce better images under certain circumstances. I started using Kodachrome in 1952. Some of its characteristics were limiting, but some enhanced the images. This is true of each film and digital process. It's not for us to quibble about such details in the photography of a master.
I agree completely with that.
Everything has its useful place, and no one method is best universally.
