A little bit of smoke visible in this vid, but certainly not huge amounts

That's it mate.. a 'mild disturbance' rather than an eclipse
The Sea Vixen is very similar and I guess, if you can find any Lightning footage where they're NOT using reheat.. that would be the same.

Don't recall
Hunters being particularly smoky, also using Avons. Very clean compared to some of the engines of the time -
Conways,
Speys,
Olympuses (Olympii?
), and yes, certainly compared to some of the American equivalents like the
J47,
J79 and
TF33.
The video with the PR9 taking off is likely to show off the trace amounts a bit more cos it doubles up on itself in the turn. Even later engines like the
Adour,
RB199 and
EJ200 (yes, even that) are capable of being fairly dirty, certainly moreso than the Avon.
Big fan of aircraft that look like they're powered by coal!

Yes.. the Hunter is rather cleaner than other users of the type. No idea why that should be
Have a dig on Pathe and you'll find plenty of footage of Valiants leaving a bit behind.. again under load but clean otherwise

From my own photos, the start up cartridge certainly does produce a lot of smoke...
but climbout looks fairly clean...

TBH Kevin.. you'd be hard pushed to see smoke visible from many other smokier jets from that angle mate. More noticeable (with the Avon particularly) is the 'accumulation' of 'exaust fumes' in a line behind the aircraft rather than the aforementioned 'Coal fired' effect
Memorable about the Canberra cartridge start (other than the initial smoke) is the lovely deep hum the engine gives as it starts to spool up. Definitely music to ones ears

Some of the earlier Jet were not too bad until Water/Meth was pumped in so perhaps that accounts for the varying amount of smoke
I have no idea which if any of these types used it

Does seem to be that way. Venoms, Vampires and Meteors don't leave much, if anything behind them. It's only til you start getting into the '50s that the engines seem to become a lot smokier. The Ghost, Goblin, Derwent and Avon are all from the 1940s, so perhaps there was a change in the way the engines worked later down the line?
Still yet to decide if the Russians have the Americans beat, though...
