I remember a lot of old pictures having an oval vignette. Is this wrong? I don't think I'm thinking of the mat. - Zepheus 21:41, 22 June 2006 (UTC)

[edit] applying an artistic vignette using software

I would like to add a link to a page on my website that deals specifically with making an artistic vignette using software.

I think this is important, as the vignetting effect has already been covered in this article, but there may well be people who, after reading the article, would like to have a go at reproducing the effect. This particular page on my website would achieve this.

Please let me know.

The page I have in mind is: http://www.digital-photography-tips.net/artistic-wedding-photography-vignette.html

[edit] Optical Vignetting (Definition)

I do not agree with the explanation of the term optical vignetting.

In my understanding, Vignetting is always caused by some kind of blocking of the light path.

The natural light-falloff (often wrongly named as natural vignetting) described by the cos4-law is not caused because the light-path is blocked somehow.

As I understand optical or technical Vignetting, it apears because the light has to pass throgh (at least) two 'holes' - no matter if they are apertures and/or lenses (or even mirrors).

Pages 12 of this pdf-file provides a very simple and consistent definition of 'Vignetting'. Also have a look at Page 11 for a rough explanation of the cos4-law.

I tried to make this clear on the german wiki-article.

Sidney Ray, Applied Photographic Optics, 2nd Ed, page 33-34, on pinholes: "A very wide angle of view is possible but the image periphery suffers vignetting by cos^4 theta losses." Page 120, on Cos^4 theta: "The radial decrease in illumination is often called natural vignetting". Helen Bach 23:42, 12 October 2007 (UTC)

[edit] Pronunciation?

i think this should be included in the page somewhere as it is a word prone to mispronunciation

[edit] example: video games

"Vignetting is commonly found on video games from the seventh generation." Where exactly? Which game or games? --96.251.75.52 (talk) 20:55, 5 June 2008 (UTC)
