Where you can find anaglyph glasses:

The first things to do is to go to your local optician or photographer.
If you found green and red glasses , you can buy it to see relief , but you can't see the colors.

You can find 3D shop addresses on the net, for examples click here. For a bunch of it try : Rainbow Symphony or 3D Glasses online. For small quantities for web surfers you can try Steve Berezin's site in the USA.
The French company SARELEC maid good paper mount glasses for anaglyphs.

If you have some colored transparency you can assemble it. You probably see relief but you will be disturbed by some ghost images and bad color.

You can assemble it with Kodak Wraten filters boughtin photographer's shop. Kodak said that filters 26 (ref 149 70 80) and 58 (ref 149 73 95) are for anaglyphs, but this filters are for red and green glasses. May be you can replace filter 58 by filter 44A (ref 149 72 21) .
Place a 3 x 4 cm rectangle of each in a paper mount cut in a 40 cm long sheet. Put the cyan filter in front of the right eye and the red filter in front of the left eye.

Owen C. Western, president of the local San Diego Stereo Camera Club, California, USA give us this help:
There are high-quality theatrical lighting filters made by Lee Filters in England, and Gam Color in USA.  Both companies offer free sample swatch books with many colors and subtle differences.  Lee Filters' address is:  Central Way, Walworth Ind. Estate, Andover, Hampshire SP10 5AN, England.  If you ask for the Designer's Edition you will receive filters bound in spectral sequence.  If you ask for the Numeric Edition, the filters are arranged in numerical sequence, which is not by color (I don't know why)! The Gam Color filters are bound in numerical order, and are in a spectral sequence. The Gam Color address is:  Gam Products, Inc., 826 N. Cole Avenue, Hollywood, CA 90038, USA. I think you will find that the Gam Color number 270 (red-orange) is an excellent combination of brightness (efficiency), while masking the red color effectively, and cancelling the cyan or blue-green.  For the other color, try the Lee Filter 116 (medium blue-green), or 183 (moonlight blue).  Another possibility is 141 (bright blue).  These are all pure filters that peak at a fairly specific wavelength.  Both companies have paper sheets showing the name and number of each color, and the spectral readout.

Some bad insight :

Someone told me that she had view my images with safety glasses colored with indelible pencil. I try and I do not see 3D!!!

I try some print on transparency sheet with many computer printer. Never this filter work for me! but Jeffrey Cooper say the contrary.

Télévision set is not adapted for anaglyphe exibition. So come back on a good computer monitor.

Attention : It is very difficult to find glasses and filter perfectly adapted to screen pigment. So you ever see light ghost images. Maybe you can try 2 pairs of glasses in order to attenuate ghost. But if you want to see high quality relief , try to make your own stereo with the method describe here.

If you can't nevertheless find it, or if you have an other solution, tell me.
