Neopan1600 @6400 - developer/agitation advice

[mmabale]

Due to my dumb gear choice at a local evening bike race, I was forced to expose Neopan 1600 @ 6400 just to get a shutter speed of at least 1/125
I know that most people rate this film's true speed at 1000, so this is closer to a 3-stop push than 2, and I've accepted that I may not salvage much from these rolls.

On my shelf, I've got a bottle of Rodinal as well as HC-110 syrup ready to use. There's also a packet of D-76 sitting around that I could mix up. (Kodak stop and fixer, too.)

Anyone get decent results any from these combos? What times and agitation would you recommend? I'm not adverse to a lot of grain as long as it doesn't get too clumpy. I'm tempted to try Rodinal stand for 90 minutes.

Thanks for your help.

I can't really help you, but just to say that I've read the true speed of this film tends to be about 640, not 1000.

I think I'd want all the help I could get on these. 6400 is asking a bit much from TMZ if you ask me, and Neopan 1600 is slower. I'd try XTOL or DD-X (I think that's the one).

Sorry, I have no personal experience with the combos you asked for. Please take this times as a start point and I am sure someone here has some hands on experience and will correct me. Dev times according to this dev time calculator set to push 3 stops, 3 inversions at start of every min and 20°C (http://www.phototec.de/infomag_erechner.php)
Neopan 1600 + Rodinal 1+25 18min30sec
Neopan 1600 + Rodinal 1+50 29min36sec
Neopan 1600 + Kodak HC-110 1+15 11min06sec
Neopan 1600 + Kodak HC-110 1+31 25min54sec
Neopan 1600 + Kodak D-76 stock 27min45sec
Neopan 1600 + Kodak D-76 1+1 33min18sec
I think the dev times look quite strange being uber exact, but thats where I would start and ask for more help. Good luck!

Just an update.

So I decided to semi-stand in Rodinal to help squeeze more out of the shadows and help mitigate the expected lack of tonal range. Dilution 1:150 for 90 minutes, swirl at 45 minutes at approximately 65 degrees. Scanned with Epson 2450 flatbed.

I was pleasantly surprised that I was able to rescue more than a handful of frames. They're still incredibly grainy and contrasty, but that was expected and I think somewhat adds to the nature of a gritty cyclocross race.

Those look great to me.

i'm a fan.

Neopan 1600 behaves very well in Sprint Film Developer at box speed, it might give good results pushing as well- HP5+ pushes very well in it.

Though, those look fantastic considering what you shot it at.

 

[mmabale]

I've never heard of Sprint. Looking at some examples on flickr, I really like the results of this combo.

P.S. Thanks for the comments everyone.

Well done! Much better than I would have expected.

I'm glad I wasn't in that race: it looks pretty tough.

better than I expected too. if you are a darkroom user, some Max preflash will bring some of the hottest highlights down, or poss a mild fogging. It'll still leave you with juicy blacks, preserve the feeling, but rein in some of the really bright areas. Still, superb result all considered. Some great shots BTW!

I know about, but have never tried to pre flash paper. I'm interested in knowing what Max preflash is for film and how you use it. Is there a link? I may try Neopan 1600 at 6400 in the near future thanks to this thread.

These shots are great, especially for the conditions. It should be clear that I like grain, most of the time.

grainhound, I was referring to flashing the paper, not neg. I know of the technique for film but have never used it. Only really applicable to those working very slowly.
