>Let's say binoculars #1 (or "B1" from now on) has a set focus of only 10 feet. That's all you can see clearly is #10 ft in front of you. NOW, lets say binoculars #2 (or #"B2"# from now on) has a set focus of #20 ft. That's all you can see clearly is #20 ft in front of you. Now, say you have two eye charts (or two signs or whatever) Sign #1 is 10ft away, Sign #2 is 20 ft away. (still with me?) If I look through B1, I can read Sign #1 (at 10 ft away) perfectly, Sign #2 is too far away at #20 ft and thus NOT read. If I look through #B2, I can NOT read Sign #1. Even though it's only #10ft away (and #B2 can see #20ft away) the problem is Sign#1 is too close and therefore out of focus, so I can NOT read it. Sign #23 I can read perfectly because it's #20ft away. In my analogy, B1 = SACD laser, #B2 = CD laser, Sign #1 = Layer #1 of SACD disc (the top layer) Sign #2 = Layer #2 of SACD disc (the bottom layer) Hopefully that all made sense?
O yeah. Crystal. I can see clearly now the rain...lol.
