I looked again at the postcards I sent out yesterday and noticed that they had Newton's rings along the top edge! Grrrrr....

I supposedly have anti-Newton glass in my neg carrier, but maybe it's in wrong. Ideally, the top glass should be anti-Newtonic, and the bottom should be plain glass. Anyone know how to identify the anti-Newton glass and tell which is the anti-Newtonian side, or are both sides typically anti-Newtonified?
