I was answering your post #101 and trying to illustrate the point I was trying to make about errors in posts here on some technical matters.

The best answer to this question was from the "respected" member who told me that stop bath didn't actually stop development ...
Stop bath does stop development.

Alright. Here is the experiment.
Film was coated with a layer of indicator dye that was quite dense, and changed hue from base to acid. It was then overcoated with a thick gelatin layer to simulate film. It was hardened normally.
This film was then "developed" in a developer and then "stopped" in a stop bath all the while the color density being recorded by transmission. The rate of change gave 2 pieces of data. One was the rate of change of pH and the second was the final pH. The first piece of data also gave an indication of the rate of diffusion of Hydrogen ion through the coating. This was done for a number of chemicals, not just acid - base transitions.
It showed that the pH drop to 4.0 was very rapid when using D-76 and several other developers.

... and as i stated
previously it would be a lot more "newbie friendly" if cranky and passive aggressive people who are tired of the same-dang-questions being asked
every week would just IGNORE those questions and move-on to more useful conundrums, like your post/experiment.
I'm sure that's not what Sean wants, though I suspect it would delight a tiny number of our crankiest membersmaybe it should be be reserved for experienced film users and no new registrations should be taken.
This too.Grumpiness seems to come and go.
Oh well, I won't digress anymore here.

Ire.At the risk of incurring ire - I'm not gonna read 5 pgs of posts - one is sufficient.
No matter what your hobby or passion - it lives & dies w/ noobies. How we handle that is a measure of worth.
A couple mentioned versions of FAQs - which is a good idea. 'Getting started in xxx is also. It doesn't require a terse response to direct an inquiry there. With several unsuccessfull searches, I asked a dumb question on filter factors & Wikipedia had it. They turned up nothing on prior questions, so I stopped looking. 'Felt dumb for asking & apprciative to the kind person that directed me there.
But one way or another - we'll do this thing well or dwindle to lost memory.
Telling them to do a google search won't help if they don't know what to type into the search engine. There are many here whose first language is decidedly not English; it's a struggle for them to articulate unfamiliar concepts in a new language. Cut them some slack.
As others have already expressed, I fail to understand why some APUGers get annoyed at questions that are posted (newbie or otherwise). Seemingly, it's easier to ignore a post that doesn't interest you than it is to post some barbed response along the lines of "this has been discussed x,xxx times already, just do a search." How does that serve APUG, which is presumably an interactive forum, not an online encyclopedia?
There are frequent posts by people asking about equipment failures (some broken spring, a malfunctioning advance lever, etc). I ignore these posts because I don't have anything to offer and am not particularly interested. But I'm not going to post something asking why they didn't search YouTube/Google or APUG archives before asking. That would seem petty and pointless.

And repeat questions, with bad answers don't help.
