In these earlier posts you said 4.6 would have a more flexible date stamp operation, so it can work prior to 1971.  I am using 4..61 beta and it's still stopping at  1971.  Have some old family photos from 1952, which turned out to be so historically significant that I did a news story on it, so would like to be able to code them properly.
Also :-)  you only have to go back to the first daguerreotype  in 1839, not  the year 1. :-)
Thanks
