Ilford XP1 storage

[Murray@uptowngallery]

A local store has an Alden 74 bulk film loader for $15.

I looked at it & picked it up & it was surprisingly heavy. I see a sticker on it for Ilford XP1 400/C41, so I assume that's what's in it.

I see that film predates XP2 - I don't know how it was stored - does it keep well if storage was non-ideal?

I'm only half interested in 35mm right now, but it seems like it's cheap enough and might have some film worth experimenting with.

There are also instructions for 'chrome' push processing ISO100 14.5 mins @ 100F on the loader - interesting why someone would put chrome push processing instructions on a bulk film loader...could it possibly have anything to do with the XP1? Cross process instrux, or?

Is it safe to assume it's a daylight loader?

Murray,

From a theoretical viewpoint:

What makes storage of any multilayer colour film more critical than that of b&w film, is that at least three layers are involved which form coloured sub-images. Storage induced deforming of the characteristic curves of those layers up to a point where they not longer are parallel cannot be corrected by filtration.

Well, if you make a chromogenic b&w film based on a one-coupler system (delivering a monochromatic image in the true sense) or use a mixture of couplers (delivering a net grey image), in both cases there is no triple system involved.

Though, there might be other storage issues involved too.

I had a roll of XP1, which had been sitting around since it was current, processed a few months ago, it did ok. I don't think I actually printed anything from it though.
I believe the Alden is a daylight loader, I think it uses a mechanical light trap, but I'd think there is some risk that someone may have opened it up to see what was inside.

Thank you.
