Push it; push it real good.

Has anyone tried this extreme push method with HP5+? HP5+ is my standard, and I have some in the camera right now that I am exposing @ 12,800 in hopes of getting similar results. In many/most developers it acts similar to Tri-x so I am hoping I can follow the directions for Tri-x and see what happens. Actually, looking @ standard Rodinal times, it seems to be 1-2 minutes less for HP5+, so maybe I will do it for a little less time.. I will let you know of my results.
 
This story is making me considering taking my Paterson tank out of the box and start processing again. Although my friendly lab does manual B&W processing, I doubt they'll do this kind of crazy stuff.

EI 12800 is exactly what I need for my current projects. Even 25000 is tempting. I've got some Neopan 1600 and Delta 3200 that I'll try torturing a bit. Any hints regarding those?
 
Marc, - i have heard from folks that it's possible to push delta3200 to extremes; try to look for such posts within photo.net "black and white film & processing" forum. There are some very experienced people, e.g. the moderator himself, lex jenkins...

Neopan is a bit different story - it is much higher contrast than delta3200, and therefore with long development times it loses midtones too easily, before anything from the shadows would come out.
 
I just finished a roll of TX @3200 today. It is destined to be souped in Rodinal tonight. Man it is going to be very weird to wait 5 minutes between agitations. I could do laundry, pay bills, all kinds of stuff while I wait.
 
OK, I just saw Neil's results in another thread. Very nice.

Can we summarize this with some kind of general guidelines for Rodinal?

Something in the vein of:

TriX at 12,800 = 1+50, 51 minutes

TriX at 3,200 = 1+50, 30 minutes

TriX at 1,600 = ???

Agitation: 5 inversions every 5 minutes, temp.= 20 deg. C / 68 deg. F (?)

Any suggestions for other films pushed in Rodinal?
I'm particularly interested in Tmax 400...

And perhaps we could put this in the "Darkroom" forum for future reference?

OK, well i got around to developing the roll. I used HP5+ @ 12800 in Rodinal 1+50, 51min and found the HP5+ to actually be quite a bit thin. Used the 5 agitations every 5 minutes method. Will have to try a longer time, or to use that 51min time for HP5+ @ 6400. Will report further when I get some scanning or further experimentation done.

Can we quys fill that Tri-x at 1600 part!?

Would the time be around 22-24minutes (in 20 Celcius)? How about agitation? Also times and agitation method for ISO800 would be nice to know...

Yes. No change in agitation. Easy enough for you to calculate the pushing formula.
 
Why not stop piddling around with absurdly high-contrast 'pushes' (= high contrast over-development) and switch to a faster film where you will get more shadow detail?

Cheers,

Roger
 
'Cause I don't give a shit about shadow detail, and like I what get from Tri-X far more than what I get from Delta 3200.

tri-x pushed to 12850

tri-x pushed to 12850

I pushed this a couple of months ago. The photos were taken in a very dark theater. I think I was shooting a 2.2 @ 1/60 In the front row I could not see my setting so I was going by feel With a 111a and a prewar uncoated prewar Summar.

1:50 rodinal 51mins but I agitated every 30 sec. which now I think might have be a little to much. 68f.

That's just about right for me.

Rodinal 1+50 22:00 60s initial, 10s every 3 minutes
