Help - FP4 underexposed by 2 stops - best dev / time?

[Matt5791]

Made a bit of a mistake and exposed some FP4 at 320ASA.

When I realised I wound on the film (120) so I can process this individual roll accordingly.

Anyone got any tips for best developer / time for this?

I normally use ID11 for general purpose work.

Thanks for any help,
Matt.

Stand development in FX-2 should do it without much loss of shadow detail AND without too much contrast.

FX-2, diluted 1+1, agitate first 30 seconds, then for 30 seconds after half an hour, leave for another hour.

FP4 in Diafine is around EI 250 apparently. Give that a try.

Thanks for the help.

Anyone know where I might obtain some FX-2 from? (in the UK?)

This is not a developer I have come across before - who makes it?

Many thanks,

Matt.

Ilford recommendation for speed increasing is DDX, and about 14 mins in that seems about right by extrapolating the given times for other EIs in Ilford's docs.

FX-2 is a do-it-yourself recipie (http://www.jackspcs.com/fx2.htm) unless you buy it ready mixed from The Formulary in the US. It needs glycin, of which the only known source is the aforementioned Formulary... I have bought stuff from them before with no problems if you want to go down that route.

Sorry, can't help with any personal experience.

Cheers, Bob.

For a short while, Monochrom in Germany had glycin in stock. So I bought some from them, thinking to make Ansco130 (print developer). Glycin has a fairly short shelf life, so I tried everything with glycin in it, and discovered the advantages on FX-2. I mix my own - and I still have plenty of glycin left.

the MDC shows FP4+ at 200 in ID-11 (1+1) for 15 minutes. I think if you went to 18 minutes or so you should be fine. The negs are going to be grainy but at least you'll have an image.

You underexposed by 1 1/3 stop, not two.

You underexposed by 1 1/3 stop, not two.

That depends on the developer. With stand developing in FX-2, you may have overexposed half a stop...

Thanks very much for the help everyone.

I would very much like to try the FX-2 route, but I haven't the time to get hold of the ingredients - I need to have these developed and printed in a few days.

As I have got the ID-11 to hand I will have a crack at that at 18 minutes - I take it that is 20/68 degrees?

The subject matter will probably suit a bit of grain anyway.

Thanks,

Matt

yes that would be at 68 degrees. good luck and let us know how things turn out.

I would suggest Kodak Xtol for push processing. The Massive Development Chart lists times for FP4+ exposed at EI's of 250, 500, and 1000.
