developing times
« on: September 07, 2014, 09:58:33 PM »
Hi guys,

I have a question regarding developing times . I have an app on my iPhone that shows me all the developing times with the developer i'm using except with this formula .

I'm going to develop some 35mm later tonight in adox adonal, but I wanted to use it 1 to 100 with my Fuji Neopan 400 shot at 400 ISO. I went on Flickr and other photosites but couldn't find what I'm looking for. If I want to do stand developing what time should I do it for, I was thinking 1 hour?

Thanks.

1 hour is pretty standard for 1:100 stand. I usually give a little inversion or two at 30 min to reduce bromide drag.

I do the same as jharr, 1 hour stand works well with rodinal, here's a tmax100 that i shot at iso400 by mistake and i knew i could count on Rodinal, the Tmax was also 25 years out of date

This is T-Max 400 expired in '91 exposed at iso 200. I had to crop this because I didn't put enough developer in the tank and the lower 1/4 of the film didn't develop. :(

Perfect thanks!

 And for fixing, should I just leave it for 5 minutes 1to9?

I was taught that the logic of stand developing is that the developer is exhausted after an hour or so--so it really isn't very time-sensitive.  A friend who got me to try it said, "rap the tank three times to loosen the air bubbles, set it down on the table and go watch a movie".

The developer should be 'locally' exhausted (near and in the emulsion layer), but there is a lot more developer in the tank that isn't being used. The point is to get developer into the emulsion and let it work to exhaustion and not replenish it with new developer by agitating. I pour in the developer, agitate for ~30sec, give it a few raps on the counter and let it sit.

Aha!  That explains "semi-stand".

I use constant agitation for 3 minutes and chrck see if it needs more
