    Wow! Great stuff.
    Thanks for that.

    I see London has no energy crisis. Comforting.

    Take another look... then compare to LA or Las Vegas or NY

    Most of the lights are internal room lights or the normal street lights.
    Very little other lighting.

    OK Picture 18 is advertising lighting.

    Well worth a look

    Yes - the comparison is valid, but the point remains.
    "OK - I may have murdered a few people, but look what Atilla the Hun
    did!"
    That's just rubbish. "Most" of the lights? Phooey! ...and BTW, "normal"
    street lights are over-engineered and obscenely wasteful, directing so much
    of their energy away from the target, as they do. (Not just in London - I'm
    not picking on you Pommies. That wouldn't be fair.)
    Yes, they certainly are.
    ,,,but you must admit - it should give us all pause about our excessive
    energy use.

    Much easier to not use (so much of) it, than to go broke generating more of
    it.

    I agree... there is a lot of light pollution generally quite apart from
    the waste of energy.

    I am all for removing lights on motorways, dual carriage ways etc.

    There is something to be said for street lights in residential or urban
    areas for security and safety of pedestrians but it should be movement
    or heat sensitive and off when there is nothing there.

    Also the electronics to do the sensing and switching could probably be
    solar/battery powered. They do this is rural areas.
    I agree. Though compared to many cities London is still running a
    blackout. In fact looking at them it made me realise how subdued
    London is when it comes to lighting.

    Yep, shame there is no technical info though.

  7. It says he uses a helicopter with a stabilised camera mount. Once you've
    added those to your armoury, it shouldn't be too hard to figure out the
    rest.

    Well, the cars leaving the roundabout show very slight blur. Assuming
    they are traveling at 30 mph then that means they cover 44 feet per
    second. I'd estimate movement of six to twelve inches and so the
    shutter speed is unlikely to be less than 1/60th. Even with a fast lens
    I'd have expected a high ISO and the pictures are impressively lacking
    in noise.

    Great link, thank you.

    I did wonder, if the harness snapped would you keep firing knowing that
    would produce some cool shots even though you would be dead.

  10. Yup, they're impressive. But we're talking big money here, so I wouldn't
    be surprised if he's using a Hasselblad H3D or something with a far
    higher resolution than the reduced versions we're seeing.
    It'd be nice to play with kit like that one day, even without the
    helicopter...

    As long as the pilot remembers you are 10 feet under the helicopter when
    he lands :)

    Was it using a gyro stabilised camera mount? :)

    For a hand held P&S through a double glazed plane window it is a nice
    picture. 20 minutes in photoshop and it could be as good as the others
    the OP showed. (Can you remove haze and mist in photoshop?)

  13. Excellent!
    Tweaking the colours in Photoshop (or whatever) to lose some of the blue
    cast would make it even better.

  14. A combination of Quick Mask and the Gradient Tool can be very useful for
    doing that. Basically, you want a graduated mask that leaves the top
    (distant) part of the image clear, fading gradually to fully masking out
    the foreground. Then any adjustment to the levels will have greater
    effect on the haziest part of the image.
    I'd suggest doing an unmasked levels adjustment first, to get the
    foreground right, then masking as above to bring up the background - but
    being careful not to overdo it.

    Its interesting he was allowed to fly so close to the Houses Of Parliament I
    understood there was an air exclusion zone doesnt detract from the images
    which are very impressive by any standard and by air doubly so.
    I just googled for the zone and PMSL the US have Norad for defence
    strategy what do we have? NatiNads <schoolboy snigger>
    (NATO Integrated Air Defence System )

    Possibly got permission to fly there? Helicopters with gyro-stabilised
    mounts are not cheap so I assume it was part of something official or
    had a good reason.
    Norad has been quite unreliable in the past.
    The US defence systems were completely inadequate on 9/11
    So in practice the US does not have a real exclusion zone.
    In practice it is easily defeated.

    Tourist helicopters can fly directly over the Thames between the Houses
    of Parliament and The London Eye

    Not quite, was set up for external threats, not internal ones.

    We have never beheaded a king over here. Never had a king either.
    Well, George III but he was mad....

    Where I was growing up (rural), street lights were few and far between and
    acted more like navigation lights - it was not so much that you could see
    anything by them, rather that you could see the next lamp post from where
    you were standing.
    No point, you already have mains available for the light. Much cheaper to
    use that than a solar cell and battery. Probally greener, as you would not
    need to manufacturer the solar cell and battery.

    Poor Trip is pregnant!! He is a man ~~~
    I know everything may happen in Star Trek, but I never think of Trip is pregnant. Poor Trip… Does he need to be far away from the spaceman?? I even find a picture in this dvds sale website, www.dvdsetshop.com.
