I had this discussion in the M Club just now, and thought it might interest folks here.

K1000 SE, M120/2.8, Lomo 400, stand developed at room temp for 45 min, blix for 60m

Tell me your c-41 stand development secrets!

I don't remember where I found the info, but it resulted from a google search. I had stand-developed in caffenol for quite a while at like 70 min (CCL) so 45 minutes sounded about right to me. I wasn't sure about 60min in blix, but figured what the heck... it sounded proportional to normal dev/blix times so I went with it. To be honest, I think this is the best C41 roll of film I've ever developed. My agitation scheme was agitate for 20-30 seconds after capping the tank, and go watch TV until the timer went off. :-)

Here's another shot from the same roll. I scanned the negative as an image and reversed it in PS with only minor tweaks to the color in a few frames, but not this one.

I am pretty sure I exposed this roll at 800, but plum forgot about increasing the time in developer for push processing. As you can see, I'm not very scientific when I develop film. I found a conversion somewhere to multiply dev time 1.25x per stop. For the record, some of the shots did look a bit underdeveloped (underexposed?) like my dog portrait above, so maybe the extra time would have yielded better results. When I get thru this month of B/W, I'll go back to my C41 stock and try this again for sure.

Thanks for the interest!

The temperature aspects of c-41 development always sounded like a hassle, and pushing c-41 more than one stop sounded like a bad scene as well, via traditional methods off development. Stand c-41 pushing sounds quite interesting. I might get one of the smaller liquid c-41 kits (maybe cinestill's?) in the next few weeks and start monkeying around.

How much of the developer are you using for these stand jobs vs. normal? Seems like B&W stand development uses much less developer concentrate than usual.

In case anyone else blunders into this topic without knowing what Stand Development is:

Stand development - Wikipedia

( This was helpful for me to understand the topic. )

It appears you are trading time for temperature rather than stand development. Stand development trades time for concentration (temps are the same with concentrations being much lower) and banks against localized depletion to avoid blocked highlights while retaining shadow detail. It appears your technique works pretty well, though the highlights look to have suffered due to excess contrast.

The question of concentration and if adding time only aids in compensating for lowered temps is one I had as well. Unless the developer concentration levels are reduced, then agreed, the longer times are only useful in dealing with room temp being used instead of 39 or 40 degrees C. Maybe some tweaks could be tried to get details back / reduce peak contrast as noted by Steve.

Probably take a pile of film to really hone this.

[jcdoss]

Thanks guys. Next time, I'll knock 5 mins off the dev time and see what results. I much prefer the longer time than mucking around with temperature regulation (which I'm sure I suck at).

[pres589]

Have you tried pushing with this method? What developer are you using?

[jcdoss]

No sir, I've used this method exactly one time. :-)

Thanks for sharing - maybe I'll try that one day. I also just purchased the CineStill TCS1000 thingy - sounds a bit over the top with the letter-number designation! I haven't had the time to try it out yet.

Ooooo...When you do, it would be cool to have a detailed report!!!

In my Jobo C-41 Press Kit instruction sheet, it gives a temperature/time chart for rotary tube processing. Something you can make at home. I have plans to check out the 75°F option. But most likely after this holiday season and the start of the new year.

Code:

STEPS                75°F     80°F     85°F     90°F     95°F     104°F

Step 2: Developer    17:30    14:15    10:15    08:00    05:45    03:30
Step 3: Blix         08:00    08:00    08:00    08:00    07:00    06:30

Step 4: Wash         Fill and empty tank at least seven times in 3 min
Step 5: Stabilizer   30 sec to 1 min at room temp. Agitate for first 15 sec

I've just had a go at this C-41 stand-development malarkey and I was jolly impressed! Here's one pic.

:cool: Lets see those ''film'' shots - Page 1225 - PentaxForums.com

A little grainy, perhaps, but I'd need to run the shots alongside a conventional process for a true comparison. It was el-cheapo Kodak 200 ISO film, after all.

[Russell W. Barnes]

I stand-developed a roll of Kodak Pro-100 in Tetenal C-41 chemistry at the weekend. I shot the film on an Olympus Trip 35 on what was a very grey overcast weekend here in the N. of England. Whilst I feel the colour rendition is consistent and accurate, the pics are a bit grainy compared to those developed by either the 30C or 38C methods recommended by Tetenal. Perhaps graininess is a function of stand-development, like it is in B&W? Not sure I'll pursue C-41 stand method but certainly worth a play.

My chemicals were mixed in early September and I have developed 5 x 400 ISO films and 1 x 100 ISO films the 'conventional' way, with times altered for exhaustion after job 4.

[jcdoss]

In my experience (n=2) stand developing results in accentuated grain.

This is definitively not stand development, it is lower temp development...
