Bob Aldridge originally posted about the results of the 
competition. here is the page with the image I am asking 
about. It is the third image down (red and whit mushrooms):

This is exactly what is going on in the image I am talking 
about.

Now that others have done it, and supposedly without any 
special "tricks" I sure would like an understandable 
explanation.

I had a look at the site, as it is the UK stereoscopic society we should see them in the bulletin soon and perhaps there will be an explanation. 
 But some time ago (early 80s) OSF (Oxford Scientific Films) were developing a technique called image plane photography or something like that and the example shown was of a camel photographed through the eye of a needle. They did not explain the technique but I got the impression that a long focuss lens was used to bring a distant image into the plane of a close up lens much like a telescope with the close up object also placed in front of this lens. More recently there have been some natural history programmes in the UK which showed close ups of insects together with the comentator in focuss at the same time. These used boroscopes a type of straight optic fibre arangement they were not stereo but the boroscopes used were very narrow so two could be placed close together for macro-stereo. Would these techniques class as special "tricks" as they do not require any manipulation of the image after the event.  P.J.Homer
