Talk:Polarizing filter (photography)

Merging this present “Polarizing filter” article with the Polarizer page == ==

I have made a study of the relevant Wikipedia pages related to this issue and have found that for many people the term Polarizing filter is synonymous with term Polarizer. As a result there is certain amount of confusion taking place. I feel a search for Polarizing filter should lead to the Polarizer page, and this present Polarizer filter page should be renamed Polarizing filter (Photography) I don’t feel that this present Polarizing filter page should be merged with the Polarizer page given that it is a specialized use of a polarizer and the article is quite lengthy. I would suggest a section on this Polarizer page which gives a quick introduction to their use in photography but then directs people to this Polarizing filter (Photography) article for more details.

Presently about 20 pages link to this page and about 3 of the links, given their context, should actually be directed to the Polarizer article. (This miss-linking is a result of the present confusion). I would be happy to take care of the re-linking. After taking care of the articles that link to Polarizing filter I would then #redirect Polarizing filter to the Polarizer page.

For me this seems like a very viable solution to the present confusion.

My Second comment

This issue is of concern to me because I am about to put forth an extensive Circular polarizers section for the Polarizer article and a Photographic polarizer is a circular polarizer. I believe the fix I’m proposing is not problematic and fair to all. Again when people use the term Polarizing filter they often mean a general polarizer and not a circular polarizer being used for a specific purpose. It would be best if they could just quickly highlight the words “polarizing filter” and create an internal link. Those who mean a Photographic polarizer will be able to quickly recognize the link they want. Unless there are objections, I will go ahead with it after I post my Circular polarizers section. Please comment.

Re-jigging of introductory sentence
Because there are a lot of people on the web using the term polarizing filter when they could just as well have used the term circular polarizer. I worked in a sentence that included a link to Wikipedia’s circular polarizer article. I also included, as briefly as possible, what the modern polarizing filter is. This seemed appropriate given the title of the article. The paragraph existing at the end of the article makes the distinction between the simple linear polarizer and the polarizing filter used with post 1970’s cameras.

I have no connection to the private link I added in the See Also section. (It’s the first hit with Google) It is only because the Wikipedia article is short that I hunted down a page that was non commercial and looked informative. Dave3 (talk) 23:00, 9 April 2010 (UTC)

First picture seems to be not accurate
The displayed effect in the first picture seems to be not only caused by the polarizing filter, but also due to a change in the colour temperature. See the especially the white clouds and the street. —Preceding unsigned comment added by 85.181.180.110 (talk) 08:33, 16 April 2010 (UTC)
 * I think the brightness of the clouds doesn't change much upon rotation of the polarizer, but the sky is dimmer. Indeed, its brightness is reduced unequally for different colors, but this effect is intrinsic to the film polarizers. Materialscientist (talk) 08:47, 16 April 2010 (UTC)
 * Could be that the polarizer is also absorbing UV and/or IR light ! Anyway, it could be Auto White Balance reacting to less blue from the sky ? Still, the effect is the effect ...

Two polarisers in series
If I put 2 identical circular polarisers in front of one another, the effect is a variable-clour filter. The attenuation is moderate, but rotating the 2nd filter has the effect of varying the colour. This is because the 1/4-wave plate can only work perfectly for green light. —Preceding unsigned comment added by 87.194.171.29 (talk) 23:20, 29 June 2010 (UTC)

Other Languages
There seems to be a problem with linking this article with similar articles in other languages. I read an article about polarizing filters in CZECH and was surprised there is no link for english. I used google to find this article but since I am a wikipedia noob I can't link those articles together (there is also Greek, Danish, Arab and others). — Preceding unsigned comment added by 195.113.29.6 (talk) 11:47, 28 April 2016 (UTC)
