Ken, that is not so impressive as how they land on Sint Maarten

Don't know what you mean by the tilting suggestion, Stefan. You want to have enough of the pebbles in the frame to tell that it is a beach.
Yes but it now makes up almost 50% of the shot and that does not work for me.
So the amount of pebbles stays the same but with just a bit more sky to change the balance, that would work better imho.

Don, it depends on the product, there are digital manuals already around and in the commercial aircraft industry you use nothing else.

oh, and let's not forget Sin City...
Indeed Sin City, nice movie.

Minority report was also quite good they used a blue colour tone almost through out the movie the get that cold feeling.

And for scenes, it's an animation but oh what nice sometimes.

About black and white, this has a great atmosphere.

Have anyone seen The New World?
It does have some nice scenes but never liked the film as an whole

With a linear you've 1 stop difference when turning and with circular none... that's still pretty good measurable in my eyes.

Still if it has no effect when shooting then it isn't a problem.

Although you said here.

If there is no polarised light, then you won't do a thing by turning a polariser.
With circular that's true but with linear it does, it can alter you exposure with 1 stop.

Then comes the question does it really alter the light with 1 stop or is the metering getting confuse?
If it's the first then no problem but if it's the later you can get an over or underexposed photo when using linear filter.

Great idea only the composition is just a bit off, if you had it tilted up a little bit it would have been bettter.

You should have waited for a plain to to land, it would have make for a more dramatic photo

In theory, yes. In practice, it doesn't seem to make much difference.
Ah okay

Thank you John, that's correct but I believe we are/were talking about Cedric's results from page 1.

I asked him to do this test
Quote:
there is an easy test which can often indicate whether or not a camera needs a circular polarizer. Attach a linear polarizer to the camera and take a TTL meter reading off a blank wall illuminated by indoor (tungsten) lighting. Don't use any kind of shiny (reflective) surface. A carpet might also make a good target. Rotate the polarizer and see if the indicated exposure changes. If it does, you need a circular polarizer.
And this was his result with a linear filter.

Hi Stefan, I have tried the test by pointing at a blank non reflecting surface and the shutter speed alters from 60th. to 125th. I tried both K10 and K20 and the same result. This was in AV mode. In TV mode the F stop altered from 5.6 to 8. I would expect these sort of changes but how can we determine how this affects the auto focus?

Great summary Don, you put it nicely.

It seems there are Linux version that can work on ARM chip, now things are getting interesting.

John just tried it with my circular polariser and it does not change exposure if I turn it.
That was when looking at a matte object, or else the highlights that change can effect the metering.
