Thanks tkamiya - I wondered if the contrast would be out, but that's not a problem once I work out the actual contrast for each box of paper. I just wondered if there was a max shelf life before they give up the ghost regardless of contrast/exposure adjustments.
Ive also seen some microphen and id-11 in the original boxes/sachets - would this be ok do you think?
When did Kodak stop making papers, 2006? Ive only used Ilford and Silverprint. There seems to be a few gems in the box.
