Have I over-processed this film?

Processed my first 120 films during the week and the results are very disappointing. I think I may have overdeveloped them.


The films were FP4 Plus and they were processed with Infosol 3. I used an iPhone app Massive Dev for timing. It recommended 4 minutes at 24 degrees, whereas Ilford say 4:30 at 20 degrees.


I must admit to being a bit disorganised, so the stop and fixer were way above temperature when I poured them into the tank.


The negatives were somewhat purple in hue, with heavier purple and green areas near the edges.


I don't think I overexposed them, as I've had others processed by a lab and they were fine.


Maybe I should ditch the app and do it the old-fashioned way. Any opinions on the images?

Difficult to say from a scan, but I notice the rebate is grey and so is the text (albeit obviously lighter) in the scan. If this is deep black in reality with white text then all would seem basically OK. If the rebate is grey then you may have over developed but 4 mins @24C does not seem too excessive, though quite long compared to 4.5m @ 20C. 4 mins may be a bit short in general to allow for good intermittent agitation, but it's unlikely to be a major issue.


The temp of the stop and fixer is not too important, as long as sufficient fixing has occurred and they are not so hot as to cause damage (reticulation etc) which is unlikely. There will be a fog over the whole negative if the fixing was very insufficient. If this is the case, you can simply re-fix the negs as even partial fixing provides a lot of protection.


What I do is contact print the neg so the rebate is just about as black as the area around the negative which receives the full light from the enlarger (the so-called "minimum black time") and then look at what the highlights are doing.

If the negatives have a 'milky' green colour in patches they are underfixed.
Wet thoroughly, refix and wash. Real pain to dry if they're already cut into strips. Of course, if cut, it means you can refix just one and compare to confirm/ eliminate the cause.
Also, 4 minutes is very short- just the time it takes to fill and empty the tank become a significant fraction of total time.
Try the 1+14 dilution, which gives a more comfortable working time (with bonus greater economy and highlight control in contrasty conditions).

Thank you both so much for that very helpful advice. Longer development time seems like a good idea. It should give more time for everything.

I generally find that with Ilford films they need longer development than suggested in any developer,even D76/id11 I find an extra minute or two helps, I tend to find that HP5, the ilford film I tended to use BF,(Before Fomapan) was a very low contrast film at the suggested time in any developer I used, but give 2 or 3 minutes more, depending on the developer, and the negative is more to my liking

Thanks for that Richard. I'm really only experimenting at the moment. I'll certainly bear your suggestion in mind.

I agree with Richard. I'm developing my FP4+ for 2 min more than suggested and some times longer. If I think my metering is off. Make sure you fix fully other wise you will get a milky foggy look to your negs
