Ilford Multigrade Filters Lifespan
It has been a long time since I've been active on these boards, since I've been without a darkroom for nearly 14 years now. However, just recently got one setup and I'm starting back into it. I have two sets of Ilford Multigrade gel filters (the smaller size and 6x6) that I originally bought sometime in the early 1990's for use with my Aristo 4500 VC enlarging head. I rarely used the smaller size, but did use the larger ones for all my 4x5 printing. Does anyone know if these filters fade or otherwise wear out over the years? Would it be advisable to buy a new set?
Thank you for any help provided.
