Fomapan 100 in replenished D23, anyone?

[Xícara]

Hello, I will shortly have a 35mm roll of Fomapan 100 (exposed at ISO 100) to develop and I will use replenished D23. Has anyone used this combination and if so, can you suggest a time/temp combination, please? I found an example on Flickr that was developed for 8 minutes at 20°C. However the Massive Dev Chart suggests 11 minutes at 20° for non-replenished D23 stock, so I would expect to need 10-30% extra time on this.
Thanks,

I haven't used d23 in years, but I have used Foma 100 a lot. I think it wise to always go a little light on the developing times recommended since foma 100 and 400 built contrast really fast. Also, the MDC times are not written in stone, so to speak, since the entries are submitted my folks just like you and not manufactures. I think I would try D23 1+1 times and go 10% light on those times also. Just a starting point until somebody else chimes in.

I should have also ask you this, is this a seasoned batch of D23 or a newly mixed batch? It will make a difference.

Hi, thanks. I'm using well seasoned D23 which I replenish with DK-25R after each use. I won't be able to do a 1+1 dilution since this will mess up the replenishment.

I generally start with +15% of the D-76 time for replenished D-23.

I wasn't talking about you going with D23 1+1, but to just use the times for D23 1+1 with your D23 replenished. I guess I didn't make myself very clear on that one. I use XT-3 replenished( same as Xtol replenished). and starting times with that are pretty much the same as Xtol 1+1 times. That's why I suggested maybe using D23 1+1 times to give it a try.

I see. Massive Dev Chart only has time for the stock solution unfortunately, but I'll do a search for this. Thanks

I guess you mean D76 1+1? That would be 10' at 20° for Foma 100, so + 15% = 11.5'. Thanks

No. I meant stock.

Time for Fomapan 100 in D76 stock is 6-7 minutes. Makes 8 minutes in D-23 replenished about right.

Ah, ok, thanks for that. That's nice it agrees with the details of the flickr post. So I'll try this. I just finished the roll. If all goes well, I'll post an image here.

All the best,

Turned out fine. Thanks for your suggestions @Alex Benjamin and @John Wiegerink . The density looked about right for most of the frames.

Looks like you're getting to where you wanted to go with D23-R and Foma 100. Foma 100 gets a little bit of poo-pooing here once in a while, but I find it a very good film for wet printing. I've been lucky I guess since I haven't had any of the problems some folks complain about.

Thanks. I realised that I'd digitised the negs at ISO 2500 on the DSLR, so the results are a bit better. I've not used Fomapan 100 much. In the past, I had some problems with flecks of emulsion shedding. This time I remembered to do a pre-soak and the negs are good. The curling does drive me mad though! I attach the same images again at ISO100:

And one more:

Yes, curling is a major problem with Foma films. I've book them in large books with a heavy weight on top thinking it would solve the curl problem. NOT! When I scan I have to use a glass carrier or I don't get even focus across the entire negative. The only emulsion flecking/flaking I have had is with Foma 200 in 120. The one thing I do like about Foma films is that in 120 size I can see the pre-dots and frame number clearly through the ruby windows of my older folding cameras.

I usually develop fomapan 100 for 8 minutes in replenished D-23; I haven't extensively tested the exact dev time yet, but 8 minutes seems to be about right for me.
