[photo-3d] My experience with the Nu-View

[penultimate@xxxxxxxxx]

I having been using the Nu-View for nearly three years.  Here are my
observations as to its performance.  The 3-D it produces is certainly
impressive at first glance.  Those with a critical eye will soon notice
the following:  

1. The flicker is annoying but can be minimized by reducing the contrast
on your TV.  It is most noticeable in the light areas of the picture.  

2.  You will notice a subtle loss of picture detail due to the fact that
each image has half the vertical resolution of an interlaced frame.
This is inherent in the right/left sequential field mode in which it
operates.

3.  Images with RAPID lateral (across the screen) movement will distort
badly.  Once again this is due to the fact that only half of the
normally interlaced fields are used for each individual image.  Do NOT
pan rapidly!

4.  This, in my opinion, is the WORSE fault of the Nu-View:  It
polarizes the light differently in the right and left images.  It acts
as if one side has a polarizer on it, and the other side doesn't.
Therefore, reflections will be prominent in one image (non-polarized
side), and absent in the other.  This can be especially bad when
shooting subjects in which the sky is reflected in water, or on any
shiny object.  This can cause retinal rivalry which, in extreme cases,
can destroy the 3-D effect altogether.  I understand there is (or was) a
fix for this problem.  It involves replacing the present polarizers in
the unit with those of the circular type.  I'm not sure if this service
is still available since i-glasses bought out the company.  My last
email correspondence with a rep there was not very satisfying.  He
didn't seem to know what I was talking about.       

5.  Lastly, it is important to used a camcorder with 37mm lens threads
(the Nu-View was optimized for this).  Otherwise, you will have to zoom
out to eliminate vignetting and lose wider angle coverage in the
process.  I have also used my Nu-View with a Sony DV camcorder with 30
mm threads (using adaptors).  This works just as well; the vignetting
problem occurs when you go larger than 37mm.

Everything considered, the Nu-View is a good unit considering the cost
vs performance issue.  I would recommend it, just don't expect it to be
perfect.
