Thanks, Peter - and Lance. :-)  

I use a tripod and take two photos, one after the other, with the same
centre of interest...having moved the tripod about 8cms in an attempt to
mimic the same degree of parellax (sp?) as you would experience with
your own eyes. 

Then you take the left image and suppress one colour and the the other
in the second image...then overlay them using the centre of interest as
the "key". 

The result can be quite striking. The only real problem with colour
images is when there is a lot of red or blue in the photo....as they
will turn to black in one eye or the other......or even both if there is
a lot of both colours. In that case, the best 3D effect is acheived
through converting to grayscale after combining the images (I think it's
after).....and they become shades of grey instead of black.
