FX1 & FX2 development - times with FP4+

[david_oconnor1]

I have heard high praises for these developers, on this forum and in the "film developer cookbook". It is available ready mix at the Photographers Formulary. However, it is not included in the "massive development chart" or in the book, although it is referenced frequently. Any starting points? Thanks in advance.

They ARE in the book. Look at pages 126 and 127 for the

formulas.

Thank you for the chemical formula location in the book. I don't see

the reference to DEVELOPMENT TIMES -such as "process FX1 undiluted

for 11 minutes @ 68 deg. agitate until your agitated"

Don't know how helpful this is - I've used Arista 125 (widely

speculated to be FP4) and I mix my own soups. I've used FX2K i.e.,

using metaborate instead of carbonate for the alkali. Often use it at

1:1 as a stand developer (i.e., agitate once at the begining and

leave it alone after that - development times were about an hour and

a half or a little longer - if you're using the carbonate alkali

version, I would think your time would be considerably shorter -

along the order of 45 mins). With normal agitation, my time were on

the order of 30 minutes - again, with the carbonate alkali, I would

imagine that times would be on the order of 15 mins. Please note that

these are based on my guesses. I would urge you to test. Cheers, DJ.

I just posted a development time for FP4+ in TFX-2 (Photographers

Formulary version of FX-2) here:

Thanks mark, I checked it out. I should have mentioned that I will be

tray developing.
