Ilford Rapid Fix 1+9 or 1+4 For Film

[Ian-Barber]

I have always mixed Ilford Rapid Fix at 1+4 for film but just been reading a webpage where the author stated that he always mixes at 1+9 to make it more economical.

Does anyone here mix it to 1+9

I've always used at 1+4, I find it very economic with films see Ilford's Datasheets for capacity.

1+4 for film, for me.
All things being equal, you will probably use much the same quantity of active chemical whatever the dilution, so in practice there will be very little real economy. I wouldn't try to outguess Ilford anyway.
Does your source use the film fix as a one shot solution? That might seem to give greater economy.

Ah, I do seem to remember him mentioning a one shot usage. I presume the same dilution can also be used for paper

Thanks David, that might have been the same person. To make life simple, I think 1+4 is the easiest route
