Boris asked "Where have you been, John?  99.9 percent of anaglyphs are
red/blue"!
I guess that I have just been seeing the world through shuttered
glasses.  The more that I work with them the better I like 'em.  The
blue/red that I had were vintage movie glasses.  These had a little bit
of green pass making them good for color anaglyphs on the PC. We gave
away hundreds of these along with a CD with JPS images and DepthCharge
software...which does not care about r/b b/r.  But I had some Mac people
that could not view using DepthCharge. 
I am planning on including anaglyph images on the next LLNL VVC CD if
there is one (current on line version is at: 
http://vvc.llnl.gov/   
 and stereo images are at: 
 http://vvc.llnl.gov/stereo/stereo.html These will now work as red/blue
rather than blue/red.  I should probably change those on my web page
too, so I can remove the warning that these images are blue/red.
Thanks for the rap upside the head Boris.  Maybe I should spring for
some good aviator style red/blue glasses and crawl out of my cave.

I got back seven unmounted rolls of Velvia 50 slide film taken of
aspens.  Very serious color saturation and fine grain is available for
those who want knock your socks off color.  The ability to offer
grainless blue skys and saturated color, with subtle gradiations thru
reds, oranges, yellows and greens were just what I needed. Kodachrome
could never fair well with the oranges of aspens for me. 1/50 and f11-8
were typical in normal light. The "best way" to shoot an aspen is
backlit against a dark background. The fact that my meter fell in the
creek and failed on the first day did not adversely affect any of my
shots.

Some have said that it is bad to shoot towards the sun.  Flare in lenses
is what is bad about it.  If your lenses are in the shade, a shot
towards the sun can be great.  Shooting from the spot of shade provided
by a tree trunk, limb, or leaf cluster flare is avoided and leaves look
like stained glass. I will have to post a few sometime.
