These are the best glasses to view 3D photos in the
1. "Lakes of the Sangres in 3D" printed book, and
2. "Lakes of the Sangres in 3D" e-book on an LCD computer monitor, and any other anaglyphs presented on pikespeakphoto.com (the books come with one pair of the glasses already).
This web store provides only for single pair glasses, either hand-hold for $2.50 (click the top thumbnail to magnify), or standard for $3.00 (bottom thumbnail). The price includes shipping & handling to USA and Canada.
To order larger quantities (10 and up) at lower price per item, please buy them directly from the STEREO EYE a Manufacturer from Japan. Standard cardboard anaglyph glasses from rainbowsymphony.com are slightly darker, but also acceptable (cheaper if ordered more than 1). So far, I haven't seen glasses that give better viewing experience than those mentioned above (anachrome or other sturdy expensive glasses are either too dark or cause more ghosting).
