This is for people that have point and shoot cameras, or can;t afford a polorizing filter.

There seems to be a misunderstanding of what a polarizing filter does.

First I will comment that this is a great little tutorial on how to deepen hues and bring new life to a photograph. Hats off to Zheng for his efforts and taking the time to make it available to everyone.

But these effects are not the primary effects of a polarizing effect. They're more like the effects that you'd get from a color intensifier filter. A polarizer filter is used to reduce glare from non-metallic surfaces (water, glass, etc). There is no way to replicate that effect in Photoshop effectively. A secondary effect that seems to have become more popular of late is that it deepens blue skies (likely the result of the way the polarizer acts on moisture in the air and the UV colors). This secondary effect CAN be duplicated in post processing, just as this tutorial does.

In any case, I just wanted to clarify the primary function of a polarizer for members that might not be familiar with filters and this wasn't intended to minimize the efforts that our good friend Zheng has done.

Plant life has alot of glare also and one reason why polarizers are so great.

Zheng, I gotta say THAT is one useful technique. Thanks a tonne. I'm gonna use it to touch up some of my "grey-blue" sky pics like this one...which I used Zheng's technique to retouch with a polarizing filter.



I just messed with the levels a bit after using the technique to reduce glare.

OK...A little addendum to my last post.

http://blog.360.yahoo.com/blog-LmDP9...FQ--?cq=1&p=31

I tried it on a photo that I took at Metrotown and still got a bit of "greenage" on the photograph, so I had to do a bit of color correction. Now this is painstaking, but had to diddle with the magic wand for a bit in Photoshop CS.

Severely color corrected result:
