I can appreciate your decision to use the same inter-lens spacing for every
image, but you seem to be implying that non-orthostereoscopy is an error. I
believe it is simply an artist and aesthetic question which is neither right
nor wrong. Nevertheless, for the benefit of those who may be trying to
figure out what to do for themselves, I will add my 2 cents by saying that I
seldom use the ortho separation. I prefer to get a full range of depth in
most images, just as I work very hard at getting a full range of contrast in
my black and white images even though the scenes my be very low contrast in
reality. (And I suppose that by definition a black and white image is not
ortho -- is that an error too?)  Do these scenes look real? Certainly not,
and in many cases I wouldn't bother with them if I could not make them look
better (to me anyway) than real. This does not make it right, it is just
another opinion for Bill and others to consider.
