Re: "Perfect" slide mounting?

[P3D Gabriel Jacob <jacob@xxxxxxxxxxxxxx>]

I would like to thank Paul Talbot for raising the question about mounting
for infinity or the window and Dr.T for explaining it. I was always confused
about this since I had always heard the two different explanations and didn't
know if it was contradictory or not. This stuff must have been posted before
but I am just know getting into projection also, so it is relevent for me
now. As I was reading Dr.T explanation I couldn't help but think how 
similiar it is to anaglyph 3D and how this explained some ambiguities. I
have noticed that alot of anaglyph pics on the web have the nearest object
sticking out of the stereo window and I find this disconcerting unless there
is a reason such as too much ghosting or alot of deviation between overlaps.
I am not saying that the object shouldn't stick out of the stereo window but
that rather, it usually doesn't work in most cases with regards to anaglyph
pics. Thus for anaglyphs in most cases the closest object should be at or
behind the surface of the window.

I know your not saying this but is the conception of the cardboard mounts.
That's interesting that historically the cardboard mounts have been
associated with "beginners". It would seem to me that the cardboard mounts
would be something the "experts" would use since they are harder to mount!
Personally I find the mounts such as RBT to be much more user friendly and
makes it easier for a beginner like me in regards to mounting 3D slides for
projection. But heck I always do everything backwards. ;-)
After experimenting with twinned P&S, beamsplitters, sidestepping SLR's,
Loreo's, Lenticular cameras, FED, etc., I am finally trying out a Realist
(courtesy of Dr.T) and boy I have to admit that yes, the pics are great!
So how much do I owe you George?
