Hi Sharron
Sunshine will help with paper, too, but as you say, not really with photographs (unless you want them fried
)
Separating them out and laying them on a clean sheet or some clean butcher's paper etc. and putting them on a table or in a room with good air circulation is one possible solution. I don't mean a stiff breeze should be coming through the window, but somewhere with gentle air movement. You could put a fan on low and oscillate it around the room. This will help to dry out whatever dampness there is in the photos.
I've also had success placing photos, books, papers etc. into a sealed plastic container along with a sachet of bicarb soda. Pour some bicarb into a gauze pocket (I make mine out of wide gauze bandages, stitch up the sides and tie with string) - you want a good handful - and place it at one end of the container. Put some photos up the other end - you will need to interleave them with some clean paper, and have them quite 'loose' if you know what I mean, to allow air to get in around them. Leave them sealed up in the container for a week or so, then replace the bicarb and leave for another week. Hopefully alot of the smell should have gone.
I hope this helps - let me know how you get on!
