Thanks Lise....I think I discovered why Corel 12 dropped the auto sepia function.  While looking for the answer, I came across some tutorial programs FOR PURCHASE.....one of them was for turning photographs into sepia tone.
  I'm so disappointed in Corel 12 I could spit.  It is the absolute pits.  It's not a cheap program, and you'd think they would get better, but this one sure didn't.  It almost seems like I have the trial version, and yet paid for the actual program.  I like my old Corel 7, but I gave it away when I 'upgraded'.
  I think tenkani uses a different graphics program if I remember correctly.
