Hi,
I'm doing a developing catch-up day today and I've got a couple of rolls I don't quite know the ISO's from and a couple rolls where I lost the data on which ISO's I used. I've read that it doesn't matter with stand dev which ISO's you've shot at. I figured that since that's supposedly the case, I would be able to chuck those different rolls in a single tank and just let the chems go to work. Is that assumption correct? I'd greatly appreciate some input on this, as I plan to develop them today (if possible).
Thanks!

Hi,
Different ISO film puts a lot of guess work into developing film especially when you've pushed or pulled some of them.
The stand development technique works well enough if you don't have time to really do it right. As you know the developer just exhausts and the process stops.
I guess you need to have enough developer in the tank to compensate for pushed rolls, since time should not be a factor.
Most people agitate a some point to prevent streaking.
Could you please post the results? I'm sure many of us have experienced this problem before.
Good luck.

I was thinking of doing 3 rolls, the amount I have, in a 5 reel tank. I'd use 6ml per roll, so 30ml total (since there's 2 vacant spots in there). I've done single rolls in a two reel tank with 3ml per roll of Rodinal (so 6ml total) with great results. As far as developing goes, I'll probably be at 18.5-19 degrees Celcius. Agitate first minute, then let it sit for 45 minutes, one inversion and then another 45 minutes. Agitate the last minute and then proceed like I normally would.
I've got two rolls of Tri-X, one of which I don't know the ISO (could be 400-1600), one which was definitely shot in the 400-1600 range and one roll of Rollei Retro shot at god knows what speeds. I just know I messed it up. Somehow I the meter on my camera was set to 1250 (maybe I thought it was Rollei 400?). We'll see what comes out of there... I'll keep you guys posted.

Here's a link discussing the use of HC-110 for stand dev.

You shouldn't need different times if they were all exposed the same (i.e. normal or the same amount of push or pull). In labs that process a lot of film, different ISO films are run together. If variations among ISOs were so great with respect to processing, then each would require it's own machine.

Don't believe all you read.
On the other hand, you can be astonishingly sloppy in developing and still get printable negatives. It's just that they may be thin and flat or harsh and contrasty.
This is what saves an awful lot of people who think they know what they're doing. They don't, but the process is very flexible.

I have found this to be a good article on stand development.
Hope it helps you.

Update: I totally forgot about the tank. 3 hours later I found it, went 'oh sh*t' and quickyl drained it. Surprisingly enough... EVERYTHING TURNED OUT GREAT! I haven't got the expertise (yet) to say if the negatives are perfect, but when I went to let them dry, they looked pretty darn good. We'll see if there's bromide streaking and halo'ing around high-contrast area's. I'll upload some pictures when I have them scanned (probably tomorrow or the day after).

Roger Hicks said:
+1. Whoever says that it doesn't matter obviously doesn't care about exposure. Think about it: if it would be true, you wouldn't need a light meter.
Again, read with caution. Different ISO and different temperature will give different results.

My experience with stand development is that different films have a nominal sensitivity. For example:
- Neopan 400: ASA 400
- Neopan 1600: ASA 640
If you exposed at nominal sensitivity you can develop together (I have used 3ml Rodinal per 35mm/36 film roll). Then you push/pull by changing the amount of developer per roll.
Of course, many exposure errors can be fixed post scanning, stand development or not. And then blame the developer for the grain that you get. But why shoot film then, in the first place ?

I agree with reading with caution.
When I process using stand development I only do 1 film at a time.

Not all that surprising if you are using really dilute developer like say Rodinal 1:100. Virtually all of the available developing agent was probably used up after about an hour. The other side of that is that at some point virtually all of the latent image has been developed and any more development is just base fogging. Mortensen worked on the latter principal more I think with his system.
There are a lot of interesting things about stand and extended development, but evenness of development is not one of the virtues. Sometimes it is fine, other times it is not at all fine.
