Talk:Composite image filter

Zobel filter
Today I see this image in the article: The caption claims it is a low-pass filter, but it appears to be a high-pass filter to me. Is swapping the C and the L all that needs to be done? --68.0.124.33 (talk) 21:13, 21 August 2008 (UTC)


 * You are right of course, that is high-pass. By all means correct the image if you want to.  It would be easier to change the caption though.  This would not change any of the meaning of the article, and high-pass is the most often used section.  Sp in ni  ng  Spark  10:11, 23 August 2008 (UTC)
