The huge change was to electronics from film.

Not only, of course, is the electronic camera so much more sensitive than any emulsion that camera people have been able to produce, but it's also the fact that you can run it for 24 hours, which you can never do with film, so that it means you can stake out somewhere for 24 hours or more and see if something happens in that 24 hours.

You don't have to be a cameraman there.

And then you whiz through at high speed and see whether anything went across.

And then it's so small.

Let me take you on a bit of a tour around Australia, starting actually with Lord Howe Island, where I was earlier on this year and where the naturalist Ian Hutton looked up.

from the shore where we were looking at tiny crabs, and he said, you see the mountain?

You're not going up there because you're a bit of a wimp.
