I have a new box of 5x7 ilford multigrade warmtone glossy paper. I also have an older box of the same paper in 8x10 size. The 5x7 paper is at least a stop faster than the 8x10 paper.
Perfectly normal. I find paper loses 1/2 a stop and 1/2 a grade over the first 6 months of use.
I don't know when it was made
As near as I can tell, opening the box and letting air get at the paper starts the process - a few sheets left in a paper safe age very quickly.
Unopened boxes keep their speed. You need the date the paper was opened, not made. Not that it will do you any good ...I am sure the manufacturing date does have some influence.
Does this happen very often?
All the time. Why does it happen? I haven't a clue. == Nicholas O.
