  1. Copied from another aviation site:

     

    Set your speed at 250 and you will get prop blur, not full circle but 3-4 blades blurring nicely. Used this technique when shooting warbirds air to air and found it acceptable.

     

    and

     

    It is quite simple. (Number of Blades) * (Prop RPM / 60) will give you the denominator of the shutter speed.

     

    For example, 2 blades, 2500RPM - The above equation gives 2 * (2500/60) = 83.33. This means that your shutter speed would have to be 1/83.33 sec or slower to get a full circle.

     

    Another example, 3 blades, 2500RPM, requires 1/125th sec.

  2. A few months since the last post.

     

    The computer I got last Christmas (the one with Windows 8) packed it in a while back. I got a replacement under warranty, and have recently set it up and started using it. I have discovered a few hidden things on Win8 and I have created a small PowerPoint slideshow to explain them. It's not a comprehensive Win8 tutorial, merely a peek at some of the different things that will confront a new user. I'm not uploading it to a server, so if anyone would like to have a look at it, PM me with your email address and I will email it to you.

  3. Hi Newbs,

     

    From the glare on the windshield and pilots visor, and the shadow on the wheels, the sun is to the right and slightly behind the photographer. Therefore, the shadow would be almost directly below the gyro, and slightly on the far side of it. The ground seems to slope slightly away from the camera, so very little shadow would be visible. See the marked area on the photo below:

  4. While you are probably right, mn, comparing the US to anywhere is a bit fruitless, After all, they are the only country where (almost) everyone walks around armed with a gun, and where you can be arrested and held in jail for stopping by a road to photograph a tourist attraction sign. They are something else again.

  5. I'm afraid you are quicker than i am Geoff. I have searched hundreds of images via Google Images, trying to narrow the search, but can't find anything on your photo.

     

    This one should also be fairly easy, but I'll throw it in anyway.

  6. Hi Geoff,

     

    You quoted the right model but I have no idea what your photo is. Is it another quiz or does it relate to my last quiz?

     

    The Supermarine 322 was intended as a torpedo dive bomber, but only two wooden prototypes were built. It was named the Dumbo, and had a wing which could have its angle of incidence changed in flight.

     

     

  7. No Geoff, I wasn't aware there was a Grob at Parafield.

     

    And yes, you are on the ball with Martin Baker. It's the MB5, superseded by the arrival of the jet age.

     

    It's getting harder to find difficult examples. How about this one?

  8. A young man with his pants hanging half off his ass,

     

    two gold front teeth, and a half inch thick gold chain

     

    around his neck; walked into the

     

    local welfare office to pick up his cheque.

     

    He marched up to the counter and said,

     

    "Hi. You know, I just H A T E drawing

     

    welfare. I'd really rather have a job.. I don't like

     

    taking advantage of the system, getting

     

    something for nothing."

     

    The social worker behind the counter said "Your

     

    timing is excellent. We Just got a job opening from a

     

    very wealthy old man who wants a chauffeur and

     

    bodyguard for his beautiful daughter. You'll have

     

    to drive around in his 2012 Mercedes-Benz CL, and

     

    he will supply all of your clothes."

     

    "Because of The long hours, meals will be provided.

     

    You'll also be expected to escort the daughter on her

     

    overseas holiday trips. This is rather awkward to say

     

    But you will also have, as part of your job, the

     

    assignment to satisfy her sexual urges as the

     

    daughter is in her mid-20's and has a rather strong

     

    sex drive."

     

    The guy, just plain wide-eyed, said,

     

    "You're bullshittin' me!"

     

    The social worker said, "Yeah, well...

     

    You started it." .....
