Stop Bath.. How important?

[pentaxuser]

That would make you about 75 years old, right?

We have a programme about spies on British TV called Spooks. So how in the hell did you work that one out about my age You're not one of those spooks, are you?

"I want to thank you and your wife for having me to dinner last night and if you say "but pentaxuser, we didn't have to you dinner last night" I'll grab you by the lapels and say : "So where hell was I? "

There's lots I can't work out these days

I know how.
If you will be 100 at your death, and at that time will have spent 40 years on Photrio, you would have been 60 (100 - 40) when you joined Photrio/APUG.
You joined in 2005 (at 60).
It is 15 years since then.
You must be 60 + 15 = 75.
QED
PS Just think what your post count will be 40 years from now!

 

[pentaxuser]

God damn it Matt, is there nothing you British Columbians cannot work out! Maybe it is living on the 49th. I had thought of this but it puts me into the English Channel unfortunately. Still better to be in BC than DC the way thing s are going tonight

That was exactly my logic.

How important is stop bath? Very important is the answer and this may be understating it given this thread has lasted nearly fifteen and a half years

If stop bath was not important, Kodak, Fuji, Ansco, Agfa, Ilford, Rollei would not have invested in research and development on stop bath.

Maybe there will be value to future historians to discover that some folks spent decades discussing the same topic over and over. I can already see the interpretations "You see, it was the reflect of a profound religious feeling that expressed itself into a techno-obstinate syncretism" "But I disagree, my dear colleague, au contraire, this is the sign of a latent incompletion of the bourgeois ambition within post-late capitalism."

And THEIR own conversation will last for years and years to come. Mwahahaha!

Famous quotes from me:

• Come on, we all know that stop bath with indicator is just so damned expensive!
  
• I pee more money in beer than I spend for stop bath.

 

[SchwinnParamount]

And a famous quote from Ron Mowrey:

• I will continue to use stop bath

Yes I feel my whimsy has somehow got lost and not just in this response.

I always use a water stop. Haven't had any problem til now.

45 years of using stop or water shows no difference in my negatives. However I tend to wash negs and prints longer than strictly necessary.

 

[JBrunner]

Well, I'm glad it's finally settled. I've been waiting for the answer for sixteen years.

 

[radiant]

This week I learned that after stop bath you can fix the negative in normal lightning.

Did AA use a stop bath?

I'd love to see those negatives! This is actually something I've been dying to try for a long time.

But why would you wish to do that? Why take the risk when you can view after fixation?

 

[alanrockwood]

But why would you wish to do that? Why take the risk when you can view after fixation?

Well, basically it's because there is no risk. So if you want to look at the negatives after the stop bath (whether acid stop or water), that's fine. If you want to wait until after fixation, that's fine too.

On the other hand, if you took the film out of the stop bath and laid it out in full sun for a few days to convert the remaining silver halide into silver, that would be another story altogether.

Quite handy if you are developing in trays, deep tanks without lids, or BTZS tubes - all of which require you to do the first steps in absolute darkness.

So are you saying that after inspection you can then fix or put it back in the developer for more development?

No - the stop bath prevents that.
The advantage is that you can turn on the lights and actually start seeing what you are doing once the stop bath has done its job.

But what is the advantage? You can't put it back in the developer, so why not put the lights on when in the fix?

I turn on the light once the paper is in stop bath. I have been doing that for years.

 

[MattKing]

Well, for one, if you are tray developing, this makes it easy to pour out the stop bath and then use the same tray for fixer. Which is great for those with limited space.
There are a lot of people who find it difficult to handle film in total darkness without daylight tanks. This cuts down on the difficulty.

Nice. You can do it for film too - it seems (of course).

How effective would a water stop bath be after Pyrocat-DH development -- good enough for the lights, or wait until the film hits the fixer? (open trays, 11x14 film) Thx...

PS...I remember AA recommending somewhere to make sure the stop bath was used at its full normal working strength (for prints).
