Hi -

I am trying to find out the asa of a roll of 16mm Ilford FP4 black and white film that I have (It's old and doesn't have a rating on it) Can anyone help?
Many thanks

It's FP4 not FP4 plus.

Gidday,

we found a bulk load of it also - Pretty sure its meant to be the same as FP4+ at 125ASA. Compared to the 30 year old plus-x and 7374 we also have we found it didn't hold up so well to the rigors of time...

Have fun though. If you've got the $$$ send some in to a lab for a snip/wedge test ;)

I don't belive that Ilford had the resorces to make Movie film any different from their still film.. They just ran the same stock though a different perforator to get the right perfs. FP3 starting in 1960, as well as FP4 and FP4Plus are all 125.

The Ilford FP artice on Wikipedia gives 1990 as the date the Plain FP4 was discontinued, so you are dealing with at least 17 year old stock.

Where it was stored (fridge or oven) over that time will affect how good it is. if you have a fair quanity, it might be worth asking your lab to run a test.
