I'm pretty sure he was not using amateur radio.  The amateur radio regs in
the UK are far less permissive on the use of airborne transmitters - there's
been a lot of discussion on this over the last couple of years on the
amateur radio high-altitude ballooning (ARHAB) lists.  Most of the time they
use the equivalent of Part 15 devices.

Flights like this are less common in the UK than in the US, but he was by no
means the first in the UK.  I suspect he got a PR firm involved to get the
press coverage - the tag "Ross Parry Syndication" is on all his photos.

As others have pointed out, this has been done in the US for over twenty
years and film cameras have been in use for most of that time until the
advent of decent small digital cameras.  The CHDK 'firmware hack' for Canon
digital cameras has opened it up even more, as you can program an SD card
and make the camera take pictures at intervals without the need for
re-wiring the shutter release to a microprocessor (this is what the UK ham
did).
