    I think the pilot fancied leaving some rubber on that untouched part of the runway.
    The really strange thing was there was no wind to speak of yesterday.
    Typical. I go away to spot some Cessnas and I miss all the excitement.

    White balance, while not wanting to start a war or anything but the Levels adjustment is an unpredictable beast.
    Even the author of the levels tutorial admits this Levels adjustments are not a “one-size fits all”. Don’t be afraid to experiment to get a feel of what works and what doesn’t. This method is often far more accurate than a one-click Auto-Levels adjustment, and as always, proper monitor calibration is very important.

    There is another much better method using a Threshold adjustment layer but that’s another story.

    Get it right first time.

    Auto white balance will only work properly when there is something white in the frame. Not much of a problem if you shoot RAW but a big one if you shoot JPEG as it can not be corrected afterwards.
    I would shoot RAW and either buy a bulk storage device or pick up new cards at Wal-Mart as you need them.

    Remember, there is no substitute for thinking your shot through and if that does not work then try something else.

    There is a lot of light coming into your camera from the sky, which is overpowering you light meter. Open up an f stop and see if that will make any difference to the aircraft but you will loose the detail in the clouds
    At Duxford, you are facing south, into the sun…. or towards the sun which is not recommended for photography.
    Get the sun at your back is the answer.

    Persevere with the manual mode, there’s not that many that are so adventurous.

    I have tried it but never been truly happy with the results. You have to be careful to minimise clouds as the movement between shots, which produces gives results.

    I was never happy with the colour renditions of HDR photography, preferring to convert to mono. The colour on some HDR photographs are ghastly.

    There is an interesting article on HDR in this months Digital Photo Magazine that may be of some use. Especially with the colour issues.

    Time for some more experimentation……

    You need to get to know your camera better. The “P” setting or Program mode is basically for people that can’t think their photos through. I tend to use Aperture Av priority for static shots, mainly about f8 but sometimes f5.6 depending on what I want to do.
    Tv or Shutter priority is used for flying shots and I have to make a judgement on which shutter speed to use and that depends on the light conditions at the time.
    Get in control of your camera by looking at what the camera light meter is reading and deciding if there is enough light to take the shot or not, or if the shutter speed is too slow for a shot.
    Static shots are easily composed and do not change, while moving shots, the background can change very quickly so more control is needed.

    All images need sharpening to some degree or other and this sharpening should be done as the very last stage in the process.

    Lastly, use the middle AF sensor for flying shots and keep it on the subject at all times, you can use all the AF points for static shots but watch which ones the camera selects, if you don’t like what you are presented with then try pressing the button and see if it selects another set of AF points better suited to the subject. Control your camera and don’t let it control you!

    There is a tutorial on nIR photography in this month’s edition of Digital Photo Magazine.
    It’s not bad.

    In my experience shutter speeds are between 20 secs on a good sunny day to two minutes on a not so good day.

    The technique really works well with organic material but falls flat with inorganic aircraft.

    Sport Mode is not the best to use as it automatically sets your camera ISO to 400 for capturing sharp images for fast moving objects.

    For prop-blur look for good lighting against a dark background and use a slow shutter speed, just how slow depends on how fast the prop is rotating.

    As a previous poster said, go to your local airport and practice on them, where if you fluff shot it is not as important as fluffing a shot at an air show.

    I hope this is of use to you.

    G-AOHI 19-1-73 BEA Ben More
    Remains were airlifted off the hill by helicopter to Glasgow Airport, An estimated 90 bags were required for the operation. The aircraft hit a snow covered mountain in a blizzard whilst on a test flight from Glasgow where work had been carried out on the aerolons. Probable destination for the remains is RAE Farnborough.

    Date: 19 JAN 1973
    Time: 14:31 UTC
    Type: Vickers 802 Viscount
    Operator: British European Airways – BEA
    Msn / C/n: 158
    Year built: 1957
    Crew: 2 fatalities / 2 on board
    Passengers: 2 fatalities / 2 on board
    Total: 4 fatalities / 4 on board
    Location: 56 km (35 mls) N of Glasgow (United Kingdom)
    Nature: Test
    Departure airport: Glasgow International Airport (GLA)
    Destination airport: Glasgow International Airport (GLA)
    Narrative:Viscount G-AOHI departed Glasgow at 14:22 GMT on a test flight which was to last about 15 minutes. The crew intended to carry out the flight in visual conditions. Weather conditions however, were marginal: rain and snow with 6km visibility, 8/8 clouds at 4000 feet and strong winds (50-60 knots) at 2000 feet.The plane had climbed to an altitude of 4000 feet when it crashed near the peak of Ben More mountain, 35 miles north of Glasgow.PROBABLE CAUSE: “The pilot did not maintain a safe altitude and gave insufficient attention to navigation when flying VFR into an area of snow covered high ground in marginal weather conditions.”

    Another two of our late colleagues who have been in the news recently are Wally Durward and Stan Kemp who died, together with two ground engineers, when Viscount G-AOHI crashed on Ben More in the Highlands in January 1973 during an air test. I well remember the event, having been posted to the Viscount at Glasgow as a new command about a month earlier! David Whittick, engineer Bob Elrick and Wally‘s son Mike organised, and held, a service at, Crianlarach Church on January 19th 2005 to dedicate an inscribed cairn, which has been installed in the churchyard in memory of the crew. The service was attended by more than seventy ex-colleagues and family members, who subsequently retired to the local village hall to exchange some memories and to enjoy some Scottish largesse.
