Speaking only for this side of the pond. How is it we have two paper size families? One is 3 1/2 x 5, 5x7, and 11x14. Not perfect multiples, but very close. The other is 4x6, 8x10, and 16x20. Perfect multiples. How did this come about? And other than 4x6, none are a perfect match for 35mm, around since the 30's. And now comes printing on inkjets and we have 8 1/2 x 11 to throw another spanner in the logic. Obviously that comes from letter size paper tradition, and one can easily do an 8 x 10 on that format. Ilford makes a Multigrade IV RC in that size....... I remember Freestyle selling 8x12 a lot of years ago, I think East German. They used to have a lot of weird emulsions and sizes on the cheap. I miss those days! So now I have another thing to keep me awake along with the price of oil, gold, the subprime mortgage mess, the dollar going down, the Iraq occupation, and foreclosures. But THIS is important! Any thoughts?
