Your HDRs give a special effect to your anaglyphs indeed.
The colours and tones are manipulated without affecting the 3d
which is a merrit by itself.
I like the results: they are sharp and ghostfree.
The wall view's (55301) red-cyan balance can easily be corrected
as is the blue wash present in all your anaglyphs.
For the rest it remains a matter of choice to use HDR to enhance
the representation of reality or to get special effects.
If you look at
http://www.flickr.
you will notice that HDR, like anaglyph 3D, is mostly used for its
special effect and not to better represent reality.
These special (colour and tone) effects are the result of the
tone-mapping process and can be applied to any picture, HDR or not.
In fact a very similar effect is obtainable using 'local histogram
equalization' found in some editors.
So, if you want the special effect, you don't need the tripot and
multiple exposures.
Only if you want to represent reality with a wider tonal range than what your camara
normally captures do you need multiple exposures.
I add one example:
- the leftmost inset represents the standard result
(Canon S3IS 100ASA F2.7 1/25 sec)
- the center inset uses a shorter exposure time to better capture the highlights.
(Canon S3IS 100ASA F2.7 1/60 sec)
- the rightmost inset uses longer exposure time to get more shadow details
(Canon S3IS 100ASA F2.7 1/10 sec)
The background represents the combined results.

Hope to see more of your HDR Didier !
(my recent entries are all HDRs too)
