will_pace_linsell Posted May 10, 2015 Share Posted May 10, 2015 Hello, I've accidentally shot a roll of Ilford FP4+ at ISO 400. I can't seem to find the recommended times/temperature for developing FP4+ at 400 in DD-X. Has anyone had any prior experience? Thanks, Will.

will_pace_linsell Posted May 10, 2015 Author Share Posted May 10, 2015 Thanks Len, I'm curious to see how the negs come out as I've heard FP4 isn't the best film to push. Link to comment Share on other sites More sharing options...
lex_jenkins Posted May 10, 2015 Share Posted May 10, 2015 <p>FP4+ pushes okay. It's a versatile film that responds well to different developers and techniques. I found it worked well with ID-11 and Microphen, but was a bit disappointing in Diafine when rated above the box speed of 125 in contrasty lighting.</p> <p>But results depend on lighting, metering and exposure biases, developer and technique, and desired results.</p> <p>For example:</p> <ul> <li>If the lighting was contrasty daylight, it's probably best to avoid push processing. Just develop normally. This will minimize the risk of excessive contrast and grain.</li> <li>If the lighting was tricky - say, stage lighting with a dark background and surroundings - the meter may have been fooled. Setting the ISO is arbitrary. What really matters is the actual exposure. In some cases push processing may help; in others, it may result in excessive contrast.</li> <li>If the lighting was flat - say, overcast or very even but dim indoor lighting - push processing may restore desirable contrast and make the midtones more satisfactory and easier to print or scan well.</li> </ul> Link to comment Share on other sites More sharing options...
glen_h Posted May 11, 2015 Share Posted May 11, 2015 <p>The massive development chart says 200 or 250 for Diafine. I forget which the box actually says, but either way it isn't a huge push. </p> -- glen Link to comment Share on other sites More sharing options...
lex_jenkins Posted May 11, 2015 Share Posted May 11, 2015 <p>In my experience FP4+ in Diafine at EI 250 for photos in contrasty lighting offered none of the advantages of Tri-X in Diafine. The negatives were extremely contrasty with little true shadow detail. Microphen was better for pushing FP4+. DDX and a few other speed enhancing developers would probably do as well.</p> <p>Diafine is a quirky developer that works very well with some films but is mediocre with others. I got excellent results with Diafine on Tri-X at 1200, Pan F+ at 50 (the only developer I tried that delivered good results at the box speed in contrasty daylight), and Delta 3200 at 1600-3200. Most other films I tried with Diafine were no better (HP5+) than with conventional developers and some were subjectively worse (TMX and TMY were odd looking, at best).</p> Link to comment Share on other sites More sharing options...
Mike Gammill Posted May 11, 2015 Share Posted May 11, 2015 <p>I once pushed the non-plus version of FP4 using Acufine (not Diafine) to an E.I. of 250 and it looked good, but Acufine is a single bath developer so not really a fair comparison. However, Microphen does offer times for an E.I. of 200. Maybe work from there. An extended water bath (2 to 4 minutes) after pouring out developer might tame the contrast. </p> Link to comment Share on other sites More sharing options...
hwa_goh Posted January 12, 2017 Share Posted January 12, 2017 <p>Hi,</p> <p>Just saw this and will add 2 time combos to help out future visitors...</p> <p>FP4+</p> <p>@ 320 ASA - D76 1:1 29min 22'C......good<br> @ 400 ASA - Ilfosol 3 1:14 12min 24'C ...... still a bit thin...better at maybe 16 min...<br> agitation 2 inv start of every minute with a water pre-wash</p> <p> </p> Link to comment Share on other sites More sharing options...
