http://www.geebeephoto.com uses a green filter a lot with HP5 and Delta 400, and it gives an effect somewhat similar to IR on foliage. X1 Green is, of course, a stronger effect than X0 Yellow-Green. There are a bunch of b&w images in his 2005 and 2006 folders (this one and the next 2 images are ftaken with a green filter). BTW the camera/lens/film/filter info is black text below the image - you have to highlight it with the cursor to see it. Simon.
