I agree with Steve. A trained eye can make a digital B&W look like film ... but the key is they've got to know what the qualities of film are and then duplicate that digitally. You can't just go into photoshop and "convert to greyscale" and badda-boom, you've got it.

More than that, I don't really know, as I'm not really into the technicalities of film. I think film has more consistent qualities to it, whereas digital has such wide-open possibilities, that more could "go wrong" on the conversion in digital.

But to make a blanket statement such as the title would show ignorance, IMO.
