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).

Unfortunately, you can't get the same effect with any filter.

A true polarization filter changes the way the image is recorded; you get detail in the image that simply is not there when you don't use a polarizing filter. You won't get the same results after the image is made no matter what you do.

I have never tried it, so I don't know how well it works, but here's a tutorial about it.

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 help 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

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.
