I doubt if it can be done. Remember as an example, a polarizing filter
prevent glare on water. How would you imitate that, unless by cloning.
But lets wait for the guys who know:-)

Do you want to remove reflections or darken the sky. Polarisers will
do both

You cannot imitated a polarizing filter in Photoshop. Now, to be clear,
that doesn't mean that you couldn't take two pictures -- one with and one
without the polarizer -- and then adjust the one without in Photoshop to
match the one with. I only mean that there is no SIMPLE way to duplicate
the effects. And there is no itemized list of instructions that you could
follow that would always work. Yes, you can darken and saturate the sky and
adjust highlights and do all kinds of wonderful things. But it won't be the
same. Photoshop is great, but you still need two filters on your camera --
a polarizer when needed, and a UV (mostly to prevent scratches on your
lens).

I have never tried it, so I don't know how well it works, but here's a
tutorial about it.
http://photoshoptutorials.ws/photosh...ng-filter.html

Talker

You can fake it darkening effect using Levels or Curves. However, you can
not fake the glare removal or reduction. This is an optical at the time of
image capture thing that can't be done post process. Unless of course you
like the clone tool a whole hell of a lot. Buy a polarizer.

Thanks.

Maybe there will be one in Photoshop 2040 ;-)

Hopefully by 2040 both you and Usenet (of which alt groups are NOT a formal
part) will be long gone.

Listen to the advice of "Talker".

The rest do not provide to you!

well, the tutorial he quotes tries to fake the effects of a polarizing
filter, but, as all the other posters in this thread have written, no
image processing can really achieve all the results a polarizing filter
will.

I have the impression that you have no idea of what you're talking about

No one wants to see your bottom...

Of what then, are alt groups a part? Usenet isn't just the Big-8, you know.

That's why some post at the top! See ... even you 'know' that!
Now ... bottom's up ...

"alt" => Alternate!
Usenet is a formal structure, but any idiot can create an 'alt' group with a
bit of cooperation from someone having a server.

And that's all the OP asked for.
He asked for a way to imitate the effect of a polariser. Not for a way to
replace it with software.
That's what the tutorial offered does. It imitates some of the effects
created by a polarising filter.
Of course, some of the effects can't be recreated by software, nomatter how
clever the technique may be, but as a vague approximation, the technique
works quite well.

Oxymoron?

You don't buy the Anarchists, Lunatics and Terrorists explanation?

Heh, Usenet is about as informal as it gets in most places. And, if you have
the cooperation of someone with a newsserver there's no reason I know of
that you couldn't "create" a group in any hierarchy you wish. Getting it
propagated might be another thing, though.
