I've a small supply of 10 year old 8"X 10 "Ilford multi-grade paper and am using it for my initial in camera negatives with some success. The paper has been subjected to all sort of bad storage conditions over the years (like extreme temperatures and moisture in a basement storage area to in an uninsulated small storage shed). This "good stuff" is going to be depleted soon and I'm wondering if anyone has experimented with ageing newer product? Like keeping it in a warm to hot place for a period of time. Generally to prolong film and paper life it's refrigerated so am assuming heating it would produce the reverse condition.
Any good ideas or successful experiments ?
