    Ian: One of my old packages of Ilfospeed has written "02 D 20 04", any clue what that means?

    Is it MG III RC Deluxe or MG III RC Rapid? Ilford had two "Multigrade III RC" papers. I used both of them extensively back in the day. Apart from slight differences in characteristic curve, MG III Rapid was marketed as having developer incorporated and therefore as being appropriate for use in rapid access or activation processors.

    So if your paper is Rapid, the fogging may be a result of incorporated developer. If it's Deluxe, I don't know why it would behave differently from Ilfospeed.

    Cadmium was added to photographic papers until the late 80's - it did an excellent job of keeping the paper from fogging. Chances are the older Ilfospeed still had cadmium in the emulsion formula. When Kodak first removed the cadmium their paper suddenly had horrid keeping properties.

    I'm using MG III that's ok except that high contrast is not possible regardless of filtration. I use it for the negs I made in my younger years following the manufacturers' instructions, i.e. too contrasty. Before I started exposing more and developing less.

    I'm using ilforbrom galeri grade 2 dont know what manufactured years but quite old about 5-8 years old, but it had light gray tend to brownish, I think it's not fog, because cant get rid of it with potasium bleach, is that because of the optical brightening agent degraded on old paper?

    Ilford changed their coding at some stage so I can't help with that one without looking at the box, Ralph Lambrecht has posted on the newer system somewhere on APUG.

    Not all emulsions contained Cadmium, it's not needed in Bromide papers and was used in Chloro-bromide papers to help maintain good contrast when these papers were processed with warm tone developers particulary when pushed to extremes. A side effect was it helped with the keeping properties.

    So for instance the old Agfa Record Rapid with Cadmium could be processewd to give very rich red-brown tones by using a dilute developer and increasing the exposure, once the Cadmium was removed that flexibility was lost.

    Something that's never commented on is that current Warmtone papers become colder toned as they age.

    No, the MG III RC was Deluxe. My friend and I just turned the last of it into photo backdrops using his method of exposing it with the lights on and dipping and rolling the developer around on it. Kind of fun.

    the bleach is potasium ferrycianide bleach.

    If we're guessing how old various papers are, any ideas on this one?:

    The batch number is L2706
    I printed to it a couple of days ago and it looks perfect to me. Cute little 2.5 x 3.5 inch prints that remind me of my grandparents' photo albums.
    I also printed some Ilford Multigrade III RC Deluxe Glossy last night with no problems. The previous owner hadn't opened it but was kind enough to write on it that they'd purchased it in May of 1994... Seventeen and a half years later and it's still going strong!
