Yes, the DSLR shot looks like a page from a beginners' text book: "Wide angle lenses make closer objects look bigger." He says 10° tilt, which might have tilted the plane of focus forward. The advice used to be to stop down a bit more, but nowadays, it would be to use focus stacking. (I'm not sure if DSLR users are as obsessed by diffraction limits as some LF users.)
As this was an article about movements, it would have been helpful to show the 20mm shot both with and without the tilt. The shot we have looks as though night was creeping in, so that might not have been possible. Perhaps we are being too demanding.
We should give credit to the digital camera. Stacking is something that it can do relatively easily, that would be very tricky with film. It's a genuinely new resource.
Forty years? You'll be starting to feel that you're nearly out of the beginner's phase, eh? Something that I'm looking forward to.
