Final Thoughts on Diafine Developer

Viva la Revolution- Steve

UPDATE April 11, 2019

Just to be clear…. I still stand by my original processing technique outlined here in FR years ago which does not use the pre wet and has slightly more agitation than the technique outlined above (metal reels and tanks only for the older process). If the film and agitation technique is perfect without a pre wet then go for it but I have found most modern films do benefit from the pre wet… the only downside is developer longevity and about 1/3 stop loss in speed.

Let The Film Testing Begin

I am heading to the Cotswolds (UK) in just over a week and running one last set of tests over┬áthe next few days…. looking at chromogenic B&W films (and converted Portra 400) compared to traditional B&W films processed in Pyro 510 (stand development)… all for the purposes of scanning.

Stay tuned!

PS- and yes that is Fuji Neopan 400CN… very hard to get here in the USA as it is not imported… made by Ilford for Fuji, based on XP2 Super but it is a different film made to Fuji Specs… time will tell.

Film Testing Kodak 400TX and Diafine Developer

Amazing couple of days running dozens of different developer tests all with 400TX… love the look of the grain and depth of this film! In the end I came back to an old friend but with a new twist. Diafine is back in my life in a big way! Diluted 1:1 and used as a one shot developer it is spot on in my JOBO with very nice grain, great tonality, no processing issues and best of all a usable EI from about 100-1250 (the chart shows 200-1600… I think 1600 is a bit on the edge for my works but is totally usable in a pinch. So again, in a JOBO speed is 4, temp does not really matter but I ran at 75F, Dilute part A and B 1:1… I did 3.5 minutes in each followed by a 2 min wash with water then fix (box time), clear (box time) and hang to dry…. easy as pie!

Of course an advantage of Diafine that I have written about here before is that many different films can be souped at the same time which is a huge time saver. Diafine negs are a bit flat and do requiere an “S” curve in PS to make me happy but I am now quite happy indeed. I will post links to Diafine articles I have written and a great one from a friend Sandy King from View Camera.

My suggest EI…. 800.

as for articles here… there are a lot!!!! Just type in Diafine in the search box and enjoy!

Also please note these were just quick scans (first set) as I am leaving tomorrow for a week of shooting but the final scan (last image) is quite nice and shows the real potential for this amazing combo.
