Which Nikon CoolPix are you using?  Am interested as it has been 
suggested that the CCD in the 950 is the same as the one used in the 
Olympus 2000Z.  There are marked differences between the colour in 
your images and those in mine using the 2000Z.  I guess the camera 
software will have some effect on the resulting images - that and the 
nature of the infrared blocking filter used in front of the CCD.

Do like the cityscapes btw - in particular downtown.jpg.  Haven't 
looked at all of the images but the tree-grove.jpg comes closest to 
images from the 2000Z.

I share your enjoyment of the "False-Colour" digital infrared and 
have had very positive feedback from some people - which was 
surprising as a few of them had a rather negative view of digital 
imagery before.....

You have probably seen the posts describing the new digital 
False-Colour images in the CoCam Gallery and CoCam does of course 
supply 89B infrared filters.
