Anaglyphs...

[P3D Shelley, Dan <dshelley@xxxxxxxx>]

Please forgive a response to a digest a few days old, but I am wading 
thru several weeks worth...

A tough quote... Although I agree with the general assertion that 
anaglyphs are not suited for projection, I think the example of an 
Edison Cylinder vs a DAT tape is a bit off. I produce anaglyphs for 
about 50% of what 3D work I churn out, and will be publishing a book 
that will be at least 50% anaglyphs in the (hopefully) near future. 
[Any of you out there heard me say that before? =)] If a true stereo 
pair is used, and the images are processed at maximum resolution with 
appropriate software, full resolution anaglyph negatives can be 
produced. 

I have made 8x10's in b/w anaglyph format that have kept people 
starring and saying "wow" for 10 minutes while my Holmes style pairs 
generally only heed 10 seconds of viewing or so. Because I can make a 
much lager image size in Anaglyph format, more details can be seen in 
the 3D image. People DO like this, and it makes it a better option for 
me. I would guess that if more people saw high quality Anaglyphs, they 
might just feel the same way. 

Just like there can be a good or bad stereo slide pair, there can be 
good and bad anaglyphs. Unfortunately, there are many more bad 
anaglyphs available to the general public than good. I am hoping that 
this will change in the future, but constantly deriding the format as 
poor, etc. will not help...

Surely some of you out there have seen high quality anaglyphs? Both the 
Sell's and I have a link on our "links" pages that go to a site that 
has a few images from the Gruber Anatomy images. These images are about 
900K (I think...) and sharp as a tack when viewed with anaglyph 
glasses. I would rate them very close to DAT tape quality in the 
analogy mentioned above. Try them, see if you don't agree...
