Stone, that's what I was looking for. Every wratten filter I've ever seen says wratten on the ring. I've never seen "Pictorial" on a ring or a box. When my internet search for "Kodak Pictorial Filters" returned zero results, it seemed like this could be a different filter, or, it could be the same animal with a different (and less used) name.
Wratten filter "marketing".
Thanks for the shout!
For some reason I read it as "CAN see the difference" rather than "CAN'T see the difference".
Much better now!
"Pictoral Yellow" probably sounded a lot less scary than Wratten #12 to your average Joe.
"Pictorial filter" Just another marketing ploy by the capitalists at the former GYF.
