Personally, I make a landscape format image roughly between 1024
and 1280 pixels wide. (Since monitors have increased in size lately, I've
been going with 1280 width recently).
It's pretty rare in my experience to see many anaglyphs that are viewed
without 3D glasses. Just make a 2D image if this is what you want,
or produce a 2D as well as 3D.
Deviation between the Red and Cyan channels is unavoidable. We try to
lessen deviation because it results in less harsh ghosting, rather than
to be viewed without glasses. Deviation is normally related to the stereo
base being used and thus the depth you want to achieve. To do what you
want would best be accomplished with close subjects that require very little
stereo base to achieve the 3D effect. When an anaglyph is very well done
and the image contains the proper composition of colors, without adjacent stark
contrasting shades that introduce harsh ghosts, an anaglyph can be made without
noticeable ghosting however, when viewed using
different equipment (glasses, monitors, calibration, etc.), the
viewing results will differ.
If we ignore the "stereo rule" of keeping the image behind the stereo
window, there will be window violations which are not only a detrimental viewing
experience, but may cause disorientation, and headaches with prolonged viewing,
contributing as one of the reasons 3D movies and pictures were always
thought of as a passing fad in the past.
Once you have knowledge and good understanding of the rules of 3D stereo
and why they are there, you may want to look into the possibility of producing
anaglyphs with little deviation. A specific type of 3D glasses are used to
view these images. Check into "PROVIEW" which I believe are 3D glasses
made with filters used for this type of anaglyph.
Another alternative is to create other forms of 3D stereo such as
side-by-side (crossview or parallel) which can be freeviewed without the use of
headwear (but not by everyone). There are yet other kinds of 3D formats as
well, but anaglyph is by far the most common because although it requires 3D
glasses, they are generally much easier to view and have larger details.
Each stereo format brings with it their own set of advantages and
disadvantages.

Brian

What is the good pixel size for this group to
keep 600K? how much % compression?
What you talk about WV is one thing that makes me
feel bad with 3D pic,
I hate to se a 3D pic without glass and see a
strong mix of blue/red details to
the point of being impossible with naked eyes to
say what the pic is about.
I like normal pictures that just become 3D with
glasses.
Can you make you mod with both colors together?
Thanks
Daniel

Much improved Daniel.
Don't make your dimensions too small when trying to cut down the file
size. Compromise by changing the compression quality along with the
size dimension.
I removed a couple more anomalies (R/R caused by mis-sync), leveled the
horizon a little, and pushed the image back behind the stereo window
(SW) to eliminate the window violation (WV) on the left bottom
corner. I send the modified version only so you can see and make sense
of my explanations.
Cheers,
Brian

Thanks all for the tips, I tried to reduce,
cut date and fix WV
