Personally, it's film and I think if some of the old masters were alive they would agree.

However ....
When camera makers like Canon and Nikon announce they're no longer developing new film bodies, but you'll be able to buy they bodies they already make - what does that tell you about what you'll have to learn?

Is digital B&W or grayscale and mono?

I decided to continue shooting film as long as they still make it and I have the gear. I don't think film will be obsolete in my lifetime ...

Right now I have one wish about digital. To buy just ONE digital body that is NOT obsolete or the value doesn't depriciate 50% as soon as you open the box.
