just wondering, could you use a graduated filter rotated so that the darker part is on the window, thus allowing it to be darkened but the rest of the room lightened? (This sounds like it would work in my little inexperience head but not certain.) If so how do you set your exposures, on the window or room?


You could, but it may or may not look pretty bad. I guess it depends on the room and the size of the window. Anyway, you would have to expose on the part that is NOT covered by the grade on the ND since the other half (the brighter part of the image) would be darker and also exposed properly.

thank you! i just thought that polarizer reduces bright light and i could use it


It does...just not the way you want it too, haha. It will act as a neutral density filter but won't do as well as a dedicated one. But a neutral density filter (non-grad) will just darken the WHOLE scene, what you want is for it to darken the window but not the room. The only way to do that, for now and that I know of, is to merge 2 or more frames together.

If you use the Cokin filter system's Graduated ND filter, you can pivot the graduation line so that the darker, filtered area of the lens is covering the bright window. That way, you can over expose the rest of the room without washing out the bright window.

That filter system is what I use. Here are some examples:

Hi everyone, I've done reading every post in this thread, learned a great deal about circular polarizer filter. I've been wanting to get one for myself for a long time. What stops me is the high prices of the well known brands like B+W, Hoya and Heliopan. The cheapest I can find is the $70 Crystal Optics

I don't mind spilling my gut to get the expensive one, if that's the only way. However I'd love to save money if the cheap ones like Crystal Optic can get me similar result.

Please share me your thought

Thank you

P.S. I own a Crystal Optic UV Filter, after some testing, it showed no image degradation.

B&H Photo has a "Great Brands" 58mm circular polarizer for $29 USD -- the sales rep I talked to said that they usually ship a Tiffen filter to fill those orders. Most of the other polarizers I saw were $40-60 in that size ...

I was actually just reading this thread yesterday... very helpful stuff!

Then today I saw this for $20 on Amazon:

Hoya 58CIR 58mm Circular Polarized Filter

Is it really a piece of crap?

PS I checked out the Cokin system as well, but boy do they have an annoying website. Also, they don't appear to sell them directly, and other places have bits and pieces of their "kits" lying around...

B&H also has a used department -- I've seen polarizers there for $12. However, they are closed (for ordering) until Sunday morning.

This is not the sort of thing you want to cheap out on. If you are going to get a filter as important as a polarizer, get a good one.

I paid a little over 100 USD for a 77mm. Very nice. Discovered at the store that just because it's a Hoya or B+W, doesn't mean that it's necessarily good. The thicker filters aren't so good IMHO.

it is NOT helpful to judge a brand of filter based on the performance you get from the equivalent sized UV filter.
