The only way to get anything more in 220 and keep it alive, like most things, would be to use it I am personally going to give some 220 a try. I have never tried 220. I do have the back for my camera but it has just sat. 220 is quite a bit of color for me to shoot though. I would be cool to see Ektar in 220.
